HDF5 now uses automake 1.10.0, - autoconf 2.61, and libtool 1.5.22. MAM - 2007/7/25. - - Changed default fortran compiler to g95 when gcc is used. - AKC - 2007/2/17. - - 'make check-vfd' can now be run from the top level directory. Not all - tests that 'make check' invokes work with certain Virtual File Drivers, - so those tests have been skipped. - MAM 2006/7/17 - - Added the variable HDF5TestExpress to control how long tests run. - Setting it to a value between 0 and 3 controls how thoroughly the - library is tested, with 0 being an "exhaustive run" and 3 being a - very quick "smoke test." 1 (a "full run") is the default. - -JML 2006/6/21 - - If both shared and static libraries are installed, now both will be - tested during 'make install'. -MAM 2006/06/21 - - Added support to explicity enable stream_vfd or shared libraries - when using parallel via the '--enable-stream_vfd' and - '--enable-shared' options, respectively. If not explicity defined, - These settings default to enabled when parallel is not used, - and disabled when parallel is used. -MAM 2006/06/17 - - Remove the flexible parallel code and the --enable-fphdf5 - configure option, it was never up to production standards - anyway. -QAK 2006/4/20 - - Added a macro hdf5_mpi_special_collective_io_works to filter out - some mpi-io packages that don't support collective IO for no IO - contributions in some processes. -KY 2006/2/16 - - Added -shlib option to link against installed shared libraries to - h5c++ and h5fc. -JML 2005/11/1 - - Added --enable-build-all option to configure, which only developers - should need to use. -JML 2005/10/24 - - Configure uses the 'TR' variable to let the user override the path - to the 'tr' utility. -JML 2005/10/17 - - Configure can recognize -lmpich as a form of MPI library. -AKC- - 2005/9/28. - - MD5 checksumming has been added to snapshot releases. Release - tarballs will be accompanied by .md5 checksum files, which can - be verified using the md5sum utility. -JML 2005/9/6 - - Some configure flags are incompatible (e.g., the C++ APIs cannot - be built using the parallel version of HDF5). configure will now - output errors when some common incompatible features are used - together. -JML 2005/9/6 - - A new API function, H5Tis_hard(), was added to the library. It - checks if a conversion function is a compiler (hard) conversion. - SLU - 2005/9/6 - - t_mpi will run the test_mpio_derived_dtype by default unless it is - known not working (indicated by macro H5_MPI_COMPLEX_DERIVED_DATATYPE_WORKS - not defined.) -AKC- 2005/8/23. - - Test execution has changed in a number of ways: - When make is invoked in parallel (using -j), sequential tests - are now executed as parallel make targets. This should make them - finish more quickly on machines with multiple processors. - Since test output is garbled when they are executed by parallel make, - tests now dump their output to foo.log files and foo.logsh files - (for test scripts). These logs are printed to the screen only - when a test fails or when all tests in the current directory have - completed successfully. - When tests pass, they will create a foo.chkexe file. - This prevents the test from executing again until the test or - main library changes. - All files generated by tests (*.chkexe, *.log, and any *.h5 files - created) can be removed by invoking 'make check-clean'. - Sequential and parallel library tests can now be invoked separately. - 'make check-s' will execute only sequential tests, and 'make check-p' - will execute only parallel tests. 'make check' will still execute - all tests. - -JML 2005/08/03 - - On windows, all.zip is deprecated. users should - read INSTALL_Windows.txt to know the details. - Reasons to deprecate all.zip: - 1. Avoid confliction for windows programmers - 2. Decrease size of CVS tree by adding all.zip - 3. Avoid using winzip as the intermediate step - --KY 2005/04/22 - - When HDF5 is created as a shared library, it now uses libtool's - shared library versioning scheme. -JML 2005/04/18 - - HDF5 now uses automake 1.9.5 to generate Makefiles.in. - This has a number of effects on users: - The Fortran compiler should be set using the environment - variable $FC, not $F9X. F9X still works, but is depreciated. - The output of make may be different. This should be only a - cosmetic effect. - make depened (or make dep) is no longer recognized, since automake - handles dependency tracking. - Some new configure options exist. --enable-dependency-tracking - and --disable-dependency-tracking are used to control automake's - dependency tracking. Dependencies are on by default *on most - platforms and compilers*. If --enable-dependency-tracking is - used, they will be enabled on any platform. However, this can - slow down builds or even cause build errors in some cases. - Likewise, --disable-dependency-tracking can speed up builds and - avoid some build errors. - Some make targets have alternate names. make check-install and - make installcheck do the same thing, for instance. - pmake on IRIX can be invoked from the root directory, but the - -V flag must be used to invoke it in any subdirectory or it - will give an error about undefined variables. - JML 2005/01 - 2005/03 - - Hardware conversion between long double and integers is also added. - SLU 2005/02/10 - - Started to support software conversion between long double and - integers. Hardware conversion will come very soon. SLU - 2005/1/6 - - Intel v8.0 compiler would infinite loop when compiling some test - code with -O3 option. Changed enable-production default compiler - option to -O2. AKC - 2004/12/06 - - Long double is assumed to be a supported C data type. It is a - stanadard C89 type. AKC - 2004/10/22 - - The IA64 will use ecc as the C++ compiler by default. - - Added some initial support for making valgrind/Purify (or similar - memory checking products) happier by initializing buffers to zero - and disabling the internal free list code. To take advantage of - this, use the "--enable-using-memchecker" configure option when - building the library. QAK - 2004/07/23 - - Fixed the long compile time of H5detect.c when v7.x Intel Compiler - is used with optimization NOT off. AKC - 2004/05/20 - - Fixed configure setting of C++ for OSF1 platform. AKC - 2004/01/06 - - Prefix default is changed from /usr/local to `pwd`/hdf5. - AKC - 2003/07/09 - - Library: - -------- - - Removed size restrictions on attributes, when using the "latest" - version of the file format. - QAK - 2007/02/21 - - Relaxed restrictions on attribute operations to allow a file ID to - be used as the "location ID". If a file ID is used, the attribute - operation will occur on the root group of the file. - - QAK - 2007/02/09 - - Enabled the CORE driver to read an existing file depending on - the setting of the backing_store for H5Pset_fapl_core and file - open flags. - SLU - 2006/11/30 - - Added new H5Gget_info_by_idx() routine to query the information about - a group according to the order within an index. - - QAK - 2006/11/27 - - Added new H5Gget_info() routine to query the information about a - group by name. - - QAK - 2006/11/27 - - Added new H5Oget_info_by_idx() routine to query the information about - an object in a group according to the order within an index. - - QAK - 2006/11/26 - - Added new H5Oget_info() routine to query the information about an - object in a group by name. - - QAK - 2006/11/26 - - Added new H5Oopen_by_idx() routine to open an object in a group - according to the order within an index. - - QAK - 2006/11/20 - - Added new H5Literate() routine to iterate over links in a group - according to the order within an index. - - QAK - 2006/11/20 - - Added new H5Ldelete_by_idx() routine to delete a link according to - the order within an index. - - QAK - 2006/11/13 - - Added new H5Lget_val_by_idx() routine to query the value of a soft link - according to the order within an index. - - QAK - 2006/11/13 - - Added new H5Lget_name_by_idx() routine to query the name of a link - according to the order within an index. - - QAK - 2006/11/12 - - Added new H5Rget_name() routine to determine the name of the object - that a reference points to, as long as the object is still - reachable in the group hierarchy. - - QAK - 2006/11/10 - - Added new H5Lget_info_by_idx() routine to query the link information - according to the order within an index. - - QAK - 2006/11/10 - - Added feature to H5Iget_name to allow retrieving the name of any - object's ID, as long as the object is still reachable in the - group hierarchy. - - LA - 2006/11/01 - - Added External and User-defined links. - External links are links from one HDF5 file to another; they - require both the name of the file and a path within that file. - User-defined links allow users to supply callback functions - for link traversals, allowing links to exhibit essentially - any behavior. - External links are a kind of user-defined link, so their default - behavior can be overridden by the user. - -JML 2006/8/23 - - Added H5Oopen and H5Oclose for opening objects of unknown type - (as link callback functions do). - -JML 2006/8/23 - - Added H5Oopen_by_addr, H5Oincr_refcount, and H5Odecr_refcount for - opening objects by address. Be very careful with these! - -JML 2006/8/23 - - Added H5Fget_intent to get the "intent" of a file (whether it - was opened with read-write access or read-only. - -JML 2006/8/23 - - Added Link Access Property Lists. They currently contain two - properties, nlinks (H5Pget/set_nlinks) and elink_prefix - (H5Pget/set_elink_prefix). nlinks controls how many soft and - user-defined traversals are allowed before HDF5 assumes it has - found a cycle (previously this defaulted to 16). - The elink_prefix is a filesystem path that is prefixed to the - names of any external link files opened using this LAPL. - -JML 2006/8/23 - - Add H5L link APIs. Old APIs (H5Glink, H5Gmove, etc.) are still - supported but deprecated. - New APIs are: - H5Llink - create a link to an object given its ID - H5Lmove - just like H5Gmove2 - H5Lcopy - copy a link without copying the underlying object - H5Lcreate_hard - like H5Glink2 for hard links - H5Lcreate_soft - like H5Glink2 for soft links - H5Ldelete - just like H5Gunlink - H5Lget_val - just like H5Gget_linkval - H5Lget_info - gets link-specific info (like H5Gget_objinfo) - - In addition, H5Gcreate_anon, H5Tcommit_anon, and H5Dcreate_anon - no longer create links to objects; objects must be manually linked - using H5Llink or they will be deleted when the ID is closed. - - Link Creation Property Lists can be used to pass character - encoding (ASCII or UTF-8) for link names and to set the Intermediate - Group Creation Flag: - H5Pset_char_encoding, H5Pget_char_encoding - H5Pset_copy_object, H5Pget_copy_object - -JML 2006/7/5 - - Added managements of collective IO supports for chunking storage - inside parallel HDF5 - 1) Implemented One IO with collective mode for all chunks in the - application by building one MPI derived datatype accross all - chunks. - 2) Implemented the decision-making support to do collective IO inside - MPI-IO per chunk. - 3) Added the decision-making support to do one IO accross all chunks - or to do multiple IOs with each IO per chunk. - 4) Added the support to handle the case some processes won't do any IOs in - collectively. - 5) Some MPI-IO package(mpich 1.2.6 or lower, e.g.) cannot handle - collective IO correctly for the case when some processes have no - contributions to IOs, a special macro is added to change - collective IO mode to independent IO mode inside HDF5 library. - - Currently we find that MPICH at Linux and vender MPI-IO package at NCSA - Altix cannot handle this case. - - "hdf5_mpi_special_collective_io_works=${hdf5_mpi_special_collective_io_works='no'}" - has been added at the end of file <ia64-linux-gnui> and - <linux-gnulibc1>. - - If MPI-IO packages at your Linux and Altix support this case, - please comment out the last line and report to us at - help@hdfgroup.org. We can tune in our configuration to - support this. - - KY - 2006/02/16 - - Added character encoding to attribute creation property lists. - JML - 2006/01/02 - - Added H5Gcopy() routine to copy objects between while keeping - data in compressed form. QAK - 2005/11/06 - - Added H5Sextent_equal() routine. QAK - 2005/11/06 - - Added HSYS_ERROR which retrieves the system error message and pushes - it to the error stack. This gives more information of the failed - system call. AKC - 2005/08/04 - - Added H5F_OBJ_LOCAL flag to H5Fget_obj_count() & H5Fget_obj_ids(), to - allow querying for objects in file that were opened with a particular - file ID, instead of all objects opened in file with any file ID. - QAK - 2005/06/01 - - Added H5T_CSET_UTF8 character set to mark datatypes that use the - UTF-8 Unicode character encoding. Added tests to ensure that - library handles UTF-8 object names, attributes, etc. -JL 2005/05/13 - - HDF5 supports collective MPI-IO for irregular selection with HDF5 - dataset. Irregular selection is when users use H5Sselect_hyperslab - more than once for the same dataset. - Currently, not all MPI-IO packages support complicated MPI derived - datatype used in the implementation of irregular - selection INSIDE HDF5. - 1) DEC 5.x is not supporting complicated derived datatype. - 2) For AIX 5.1, - if your poe version number is 3.2.0.19 or lower, - please edit powerpc-ibm-aix5.x under hdf5/config, - Find the line with - << hdf5_mpi_complex_derived_datatype_works>> - and UNCOMMENT this line before the configure. - check poe version with the following command: - lpp -l all | grep ppe.poe - 3) For Linux cluster, - if mpich version is 1.2.5 or lower, collective irregular selection - IO is not supported, internally independent IO is used. - 4) For IRIX 6.5, - if C compiler version is 7.3 or lower, collective irregular selection - IO is not supported, internally independent IO is used. - 5) For platforms which internally used mpich, if the - mpich version is 1.2.5 or lower, please find the - corresponding config file and add - hdf5_mpi_complex_derived_datatype_works='no' at the - end of the configuration file. For example, at NCSA - SGI Altix, the internal mpich library is 1.2.5. So - hdf5_mpi_complex_derived_datatype_works='no' should be - added at the end of the config file ia64-linux-gnu. - KY - 2005/09/12 - We also found not all MPI-IO packages support collective IO with one - or more processes to have no contributions to IO. - For mpich version 1.2.6 or lower and all IRIX machine, - if the library checks that there are no IO contributions for some - processes, collective IO request is replaced with - independent inside HDF5. - KY - 2006/05/04 - - - HDF5 N-bit filter - HDF5 support N-bit filter from this version, - The N-Bit filter is used effectively for compressing data of N-Bit - datatype as well as compound and array datatype with N-Bit fields. - KY - 2005/04/15 - - HDF5 scaleoffset filter - HDF5 supports scaleoffset filter for users to do data - compression through HDF5 library. - Scale-Offset compression performs a scale and/or offset operation - on each data value and truncates the resulting value to a minimum - number of bits and then stores the data. - Scaleoffset filter supports floating-point and integer datatype. - Please check the HDF5 reference manual for this. - KY - 2005/06/06 - - Retired SRB vfd (--with-srb). Functions H5Pset_fapl_srb and - H5Pget_fapl_srb were removed. EIP - 2005/04/07 - - Retired GASS vfd (--with-gass). Functions H5Pset_fapl_gass and - H5Pget_fapl_gass are removed too. AKC - 2005/3/3 - - Pablo was removed from the source code EIP - 2005/01/21 - - Modified registration of SZIP to dynamically detect the presence - or absence of the encoder. Changed configure and Makefiles, - and tests to dynamically detect encoder. BEM - 2004/11/02 - - Added function H5Pget_data_transform, together with the previously - added H5Pset_data_transform, to support the data transform - feature. AKC - 2004/10/26 - - Compound datatype has been enhanced with a new feature of size - adjustment. The size can be increased and decreased(without - cutting the last member) as long as it doesn't go down to zero. - No API change is involved. SLU - 2004/10/1 - - Put back 6 old error API functions to be backward compatible with - version 1.6. They are H5Epush, H5Eprint, H5Ewalk, H5Eclear, - H5Eset_auto, H5Eget_auto. Their new equivalent functions are - called H5Epush_stack, H5Eprint_stack, H5Ewalk_stack, - H5Eclear_stack, H5Eset_auto_stack, H5Eget_auto_stack. SLU - - 2004/9/2 - - 4 new API functions, H5Tencode, H5Tdecode, H5Sencode, H5Sdecode were - added to the library. Given object ID, these functions encode and - decode HDF5 objects(data type and space) information into and from - binary buffer. SLU - 2004/07/21 - - Modified the way how HDF5 calculates 'pixels_per_scanline' parameter for - SZIP compression. Now there is no restriction on the size and shape of the - chunk except that the total number of elements in the chunk cannot be - bigger than 'pixels_per_block' parameter provided by the user. - EIP - 2004/07/21 - - Added support for SZIP without encoder. Added H5Zget_filter_info - and changed H5Pget_filter and H5Pget_filter_by_id to support this - change. JL/NF - 2004/06/30 - - SZIP always uses K13 compression. This flag no longer needs to - be set when calling H5Pset_szip. If the flag for CHIP - compression is set, it will be ignored (since the two are mutually - exclusive). JL/NF - 2004/6/30 - - A new API function H5Fget_name was added. It returns the name - of the file by object(file, group, data set, named data type, - attribute) ID. SLU - 2004/06/29 - - Added support for user defined identifier types. NF/JL - 2004/06/29 - - A new API function H5Fget_filesize was added. It returns the - actual file size of the opened file. SLU - 2004/06/24 - - New Feature of Data transformation is added. AKC - 2004/05/03. - - New exception handler for datatype conversion is put in to - replace the old overflow callback function. This exception - handler is set through H5Pset_type_conv_cb function. - SLU - 2004/4/27 - - Added option that if $HDF5_DISABLE_VERSION_CHECK is set to 2, - will suppress all library version mismatch warning messages. - AKC - 2004/4/14 - - A new type of dataspace, null dataspace(dataspace without any - element) was added. SLU - 2004/3/24 - - Data type conversion(software) from integer to float was added. - SLU - 2004/3/13 - - Data type conversion(software) from float to integer was added. - Conversion from integer to float will be added later. - SLU -2004/2/4 - - Added new H5Premove_filter routine to remove I/O pipeline filters - from dataset creation property lists. PVN - 2004/01/26 - - Added new 'compare' callback parameter to H5Pregister & H5Pinsert - routines. QAK - 2004/01/07 - - Data type conversion(hardware) between integers and floats was added. - SLU 2003/11/21 - - New function H5Iget_file_id() was added. It returns file ID given - an object(dataset, group, or attribute) ID. SLU 2003/10/29 - - Added new fields to the H5G_stat_t for more information about an - object's object header. QAK 2003/10/06 - - Added new H5Fget_freespace() routine to query the free space in a - given file. QAK 2003/10/06 - - Added backward compatability with v1.6 for new Error API. SLU - - 2003/09/24 - - Changed 'objno' field in H5G_stat_t structure from 'unsigned long[2]' - to 'haddr_t'. QAK - 2003/08/08 - - Changed 'fileno' field in H5G_stat_t structure from 'unsigned long[2]' - to 'unsigned long'. QAK - 2003/08/08 - - Changed 'hobj_ref_t' type from structure with array field to 'haddr_t'. - QAK - 2003/08/08 - - Object references (hobj_ref_t) can now be compared with the 'objno' - field in the H5G_stat_t struct for testing if two objects are the - same within a file. QAK - 2003/08/08 - - Switched over to new error API. SLU - 2003/07/25 - - Parallel Library: - ----------------- - - Added mpich2 as a testing "platform" informally. AKC - 2005/9/28. - - A dataset created in serial mode with H5D_ALLOC_TIME_INCR allocation - setting was not extendible, either explicitly by H5Dextend or - implicitly by writing to unallocated chunks.

SLU - 2003/10/03 - - Changed output of "OID"s from h5dump from "<number>-<number>" to - "<number". This affects both the "regular" and XML output. - QAK - 2003/08/08 - - Changed output of file IDs and "OID"s from h5ls from - "<number>:<number>:<number>:<number>" to "<number>:<number>" - QAK - 2003/08/08 - - High-Level APIs: - ------ - - Fortran interfaces for the Image, Table and Lite APIs. PVN - 2007/5/1 - - New HDF5 Dimension Scale API (H5DS) allows dimension scales to be - created in an HDF5 file and associated with specific datasets. PVN - 2007/5/1 - - There are two new functions in the Lite library, H5LTtext_to_dtype - and H5LTdtype_to_text. H5LTtext_to_dtype creates a HDF5 data type - given a text description; H5LTdtype_to_text converts a data type - to text description. Only DDL definition is supported as text - desciption now. SLU - 2006/05/17 - - Added Packet Table API for creating tables with less overhead than - H5TB API. Added C++ wrapper for Packet Tables. See documentation. - JML - 2004/03/28 - - Documentation - ------------- - - The documentation for this release is largely complete, but - trails the source code. A few of the newer functions are - not yet documented. FMB - 2007/04/18 - - The user documents for this release can be accessed directly at - this location: - http://www.hdfgroup.uiuc.edu/HDF5/doc_1.8pre/doc/ - The most recent document versions (updated daily) in the - 1.8 development branch can be accessed at this location: - http://www.hdfgroup.uiuc.edu/HDF5/doc_dev_snapshot/H5_dev/ - FMB - 2007/04/18 - - -Support for new platforms, languages and compilers. -======================================= - - Added support for Free-BSD on amd64 with GNU C and Fortran compilers - 4.2.1 - EIP - 2007/06/25 - - Added support for sequential and parallel libraries for Intel 64 Linux - cluster (abe.ncsa.uiuc.edu). Among three MPICH packages available on - this machine, only Open MPI works. The VMI has seg fault in hyperslab.c - and bittests.c tests. The MVAPICH2 complained about mpd not running - the parallel test. (see Known Problems section for more info) - EIP - 2007/06/25 - - Added support for HPUX11.23 for both 32 and 64-bit; HDF5 C++ - - Added support for 64-bit Windows with Visual Studio .NET and 2005. - SJW - 2007/06/25 - - Added suport for HPUX11.23 for both 32 and 64-bit; HDF5 C++ - shared library is not supported with +DD64 flag. - EIP - 2006/06/22 - - Added support for VAX floating numbers for Alpha Open VMS 7.3.2 - EIP - 2006/05/05 - - Fixed broken make.com files in tools directories - EIP - 2006/05/05 - - Added support for Alpha Open VMS 7.3.2 EIP - 2006/04/15 - - Added support for Cray X1. JML - 2005/10/03 - - PGI Fortran compiler is supported on Linux64 systems (x86_64) - EIP - 2004/08/19 - - Absoft compiler f95 v9.0 supported on Linux 2.4 - EIP - 2004/07/29 - - HDF5 Fortran APIs are supported on Mac OSX with IBM XL Fortran - compiler version 8.1. This is a default compiler. - - HDF5 Fortran APIs are supported on MAC OSX with Absoft F95 compiler - version 8.2; set F9X environment varibale to f95, for example - setenv F9X f95 - Use --disable-shared --enable-static configure flags when Absoft - compiler is used. - EIP - 2004/07/27 - - HDF5 Fortran APIs are supported on MAC OSX with IBM XL Fortran - Compiler version 8.1 Use "--disable-shared --enable-static" - configure flags along with the "--enable-fortran" flag to build - Fortran library. EIP - 2004/01/07 - -Bug Fixes since HDF5-1.6.0 release -================================== - - Library - ------- - - Changed library's behavior for reading files that might have - corrupted object header information from a previous (buggy) - version of the library. By default, the library now rebuilds the - correct object header information instead of issuing an error. - Previous "strict" file format interpretation can be enabled with - the "--enable-strict-format-checks" configure option. - QAK - 2008/01/13 - - Fixed several bugs with writing fill values for datasets that have - a variable-length datatype or component datatype. QAK - 2007/06/19 - - STDIO driver didn't support files bigger than 2GB because the OFFSET - parameter of fseek is of type LONG INT, not big enough for big files. - Use fseeko instead for big files if it's available on the system. - SLU - 2007/4/5 - - Fixed a bug in H5Sselect_valid() that caused an incorrect value to - be returned (0) instead of FAIL on error conditions such as the - selection or extent not being defined. CMC - 2007/01/17 - - Fixed the MULTI driver problem (Bug #731) that corruptted the data. - SLU - 2007/1/12 - - Fixed file corruption bug which could write an incorrect number of - messages to an object's header under certain circumstances. - Generally, the sequence of actions to generate this bug looks - like this: - - Create an object - - Close the file - - Re-open the file - - Add 2 (or more) attributes to the object - - Close the file - - Re-open the file - - Delete one of the attributes on the object - - Add a smaller attribute to the object - - Delete the smaller atttribute on the object - - Add a larger attribute on the object - - After this, the number of header messages stored for the object - will be off by one. Other sequences of modifying attributes on an - object could also trigger this bug. If you are opening an - object and the bottom few messages of the HDF5 error stack - resembles this, the object has been affected by this bug: - - #007: ../../hdf5_v1.6/src/H5C.c line 3887 in H5C_load_entry(): unable to load entry - major(08): Meta data cache layer - minor(40): Unable to load metadata into cache - #008: ../../hdf5_v1.6/src/H5Ocache.c line 332 in H5O_load(): corrupt object header - too few messages - major(12): Object header layer - minor(40): Unable to load metadata into cache - - Specifically, "corrupt object header" is the best string to search - for in the HDF5 error stack output. - - If your files have been affected by this bug, or you are concerned - that your files might have been, please contact the HDF Helpdesk - at help@hdfgroup.org for a tool to detect and repair files - affected by this problem. QAK - 2006/6/16 - - Fixed various problems with retrieving names of objects, especially - with mounted files. QAK - 2005/12/25 - - Fixed core dump when closing root groups opened through two different - file handles that operate on the same actual file. QAK - 2005/10/02 - - Corrected errors when performing various operations on a group opened - by dereferencing an object reference. QAK - 2005/07/30 - - Fixed a bug with named datatypes where a copy of a named datatype - used to create a dataset would accidentally use the original - named datatype for the dataset's datatype. QAK - 2005/07/23 - - Made H5Fget_name() be consistent and always return name of actual - file the ID is in. (Instead of the name of the top file in a - file mounting hierarchy). QAK - 2005/07/19 - - Reworked internal file mounting semantics to hopefully eliminate - mounting problems. We now require that files that are mounting - together all have the same "file close degree". QAK - 2005/07/19 - - More bug fixes on holding open files that are mounted and have - IDs open. QAK - 2005/07/14 - - Don't unmount child files until the parent file actually closes. - (Previously, if an object is holding open a file, the child files - would get unmounted too early). QAK - 2005/07/05 - - Fixed bug where unmounted files could cause the library to go into - an infinite loop when shutting down. QAK - 2005/06/30 - - The library didn't save the information of family driver in file. - The original file member size was lost after file was closed (see - bug #213). This has been fixed by saving driver name and member - file size in the superblock. SLU - 2005/6/24 - - Fixed bug with hyperslab selections that use selection offsets and - operate on chunked datasets going into infinite loop or dumping - core. QAK - 2005/06/17 - - Corrected memory leak and possible corruption when opening a group. - QAK - 2005/06/17 - - Added check for opaque datatype tags being too long (check against - H5T_OPAQUE_TAG_MAX, currently set to 256). QAK - 2005/06/14 - - Fixed various errors in maintaining names for open objects in the - face of unusual mount & unmount operations. QAK - 2005/06/08 - - "SEMI" and "STRONG" file close degree settings now apply only to the - particular file ID being closed, instead of operating on all open - file IDs for a given file. QAK - 2005/06/01 - - For family driver, the library didn't save member size in file. - When file is reopened, the size of 1st member file determine the - member size. Now member size is saved in file and is used to - define member file size. Wrong file access property of member size - will result in a failure. Using any other driver except family - will cause library to return error. So is multi driver. SLU - - 2005/05/24 - - Fixed error in opening object in group that was opened in mounted - file which has been unmounted. QAK - 2005/03/17 - - Fixed a racing condition in MPIPOSIX virtual file drive close - function. Now all processes must completed the close before any - of them is returned. This prevents some "faster" processes start - accessing the file for another purpose (e.g., open with truncate) - while other "slower" processes have not closed the same file with - the previous purpose. AKC - 2005/03/01 - - H5Tget_member_value calls for enum datatype didn't return correct - value if H5Tenum_valueof was called first. It's fixed. SLU - - 2005/02/08 - - For variable-length string, H5Tget_class returned H5T_STRING as its - class. But H5Tdetect_class and H5Tget_member_class considered it - as H5T_VLEN. This is fixed to let all these 3 functions treat it - as H5T_STRING. SLU - 2005/02/08 - - The byte order of 1-byte integer types was fixed as little endian - even on a big-endian machine. This has been corrected. SLU - - 2005/02/07 - - Fix segmentation fault when calling H5Fflush with an attribute that - hasn't had a value written to it open. QAK - 2004/10/18 - - Back up supporting bitfield and time types in H5Tget_native_type. - Leave it to future support. The function simply returns error - message of "not support" for bitfield and time types. - SLU - 2004/10/5 - - Fixed address check in Core VFL driver to avoid spurious address/size - overflows for odd valued addresses and/or sizes. QAK - 2004/09/27 - - Fixed parallel bug in which some processes attempted collective - I/O while others did independent I/O. Bug appeared when some - processes used point selections, and others didn't. JRM - 2004/9/15 - - Corrected error where dataset region references were written in an - incorrect way on Cray machines. PVN & QAK - 2004/09/13 - - The H5Tget_native_type now determines the native type for integers - based on the precision. This is to avoid cases of wrongly converting - an int to a short in machines that have a short of 8 bytes but with - 32bit precision (e.g Cray SV1). PVN - 2004/09/07 - - Changed H5Dread() to not overwrite data in an application's buffer - with garbage when accessing a chunked dataset with an undefined - fill value and an unwritten chunk is uncountered. QAK - 2004/08/25 - - Fixed error which could cause a core dump when a type conversion - routine was registered after a compound datatype had been - converted and then an equivalment compound datatype was converted - again. QAK - 2004/08/07 - - Fixed memory overwrite when encoding "multi" file driver information - for file's superblock. QAK - 2004/08/05 - - Fixed obscure bug where a filter which failed during chunk allocation - could allow library to write uncompressed data to disk but think - the data was compressed. QAK - 2004/07/29 - - Fixed bug where I/O to an extendible chunked dataset with zero-sized - dimensions would cause library to fail an assertion. - QAK - 2004/07/27 - - Fixed bug where chunked datasets which have filters defined, - allocation time set to "late" and whose chunks don't align with - the dataspace bounds could have incorrect data stored when - overwriting the entire dataset on the first write. QAK - 2004/07/27 - - Added check to ensure that dataspaces have extents set. JML-2004/07/26 - - Fixed bug on some Solaris systems where HDF5 would try to use - gettimeofday() when that function didn't work properly. - JML - 2004/07/23 - - Fixed bug in H5Sset_extent_simple where setting maximum size to - non-zero, then to zero would cause an error. JML - 2004/07/20 - - Allow NULL pointer for buffer parameter to H5Dread & H5Dwrite - when not writing data ("none" selection or hyperslab or point - selection with no elements defined). QAK - 2004/07/20 - - Calling H5Gcreate() on "/" or "." throws an error instead of - failing quietly. JML - 2004/07/19 - - Fixed bug where setting file address size to be very small could - trigger an assert if the file grew to more than 64 KB. Now throws - an error and data can be recovered. JL/NF - 2004/07/14 - - Fixed bug where "resurrecting" a dataset was failing. - QAK - 2004/07/14 - - Fixed bug where incorrect data could be read from a chunked dataset - after it was extended. QAK - 2004/07/12 - - Fixed failure to read data back from file of compound type with - variable-length string as field. SLU - 2004/06/10 - - Fixed potential file corruption bug when a block of metadata could - overlap the end of the internal metadata accumulator buffer and - the buffer would be extended correctly, but would incorrectly - change it's starting address. QAK - 2004/06/09 - - Opaque datatype with no tag failed for some operations. Fixed. - SLU - 2004/6/3 - - Fixed potential file corruption bug where dimensions that were - too large (a value greater than could be represented in 32-bits) - could cause the incorrect amount of space to be allocated in a - file for the raw data for the dataset. QAK - 2004/06/01 - - Fixed dtypes "sw long double -> double" failure in QSC class - machines. AKC - 2004/4/16 - - Fixed problem with fletcher32 filter when converting data of different - endianess. PVN - 2004/03/10 - - Fixed problem with H5Tget_native_type() not handling opaque fields - correctly. QAK - 2004/01/31 - - Fixed several errors in B-tree deletion code which could cause a - B-tree (used with groups and chunked datasets) to become corrupt - with the right sequence of deleted objects. QAK - 2004/01/19 - - Fixed small internal memory leaks of fill-value information. - QAK - 2004/01/13 - - Fixed bug that caused variable-length datatypes (strings or sequences) - used for datasets in files with objects that were unlinked to - fail to be read/written to a file. QAK - 2004/01/13 - - Detect situation where szip 'pixels per block' is larger than the - fastest changing dimension of a dataset's chunk size and disallow - this (due to limits in szip library). QAK - 2003/12/31 - - Fixed bug with flattened hyperslab selections that would generate - incorrect hyperslab information with certain high-dimensionality - combinations of start/stride/count/block information. - QAK - 2003/12/31 - - Fixed bug with variable-length datatypes used in compound datatypes. - SLU - 2003/12/29 - - Fixed bug in parallel I/O routines that would cause reads from - "short datasets" (datasets which were only partially written out) - to return invalid data. QAK & AKC - 2003/12/19 - - Fixed bug where scalar dataspaces for attributes were reporting as - simple dataspaces. QAK - 2003/12/13 - - Fixed problem with selection offsets of hyperslab selections in - chunked datasets causing the library to go into an infinite loop. - QAK - 2003/12/13 - - Fixed H5Giterate to avoid re-using index parameter after iteration - callback has been called (allows iteration callback to modify the - index parameter itself). QAK - 2003/12/06 - - Fixed various floating-point conversion problems, including a - change which could corrupt data when converting from double->float. - QAK - 2003/11/24 - - Changed "single process" metadata writing in library to collective - I/O by all processes, in order to guarantee correct data being - written with MPI-I/O. QAK - 2003/11/20 - - Fixed problems with fill values and variable-length types and also - I/O on VL values that were set to NULL. QAK - 2003/11/08 - - Fixed problems with MPI datatypes that caused ASCI Q machine to - hang. QAK - 2003/10/28 - - Removed HDF5_MPI_PREFER_DERIVED_TYPES environment variable support, - since it had no benefit. QAK - 2003/10/28 - - Single hyperslab selections (which were set with only one call to - H5Sselect_hyperslab) that had dimensions that could be "flattened" - but were interspersed with dimensions that could not be flattened - were not correctly handled, causing core dumps. QAK - 2003/10/25 - - Fixed incorrect datatype of the third parameter to the Fortran90 - h5pset(get)_cache_f subroutine (INTEGER to INTEGER(SIZE_T)) - EIP - 2003/10/13 - - Fixed problems with accessing variable-length data datatypes on - Crays. QAK - 2003/10/10 - - Fixed potential file corruption bug when too many object header - messages (probably attributes, from a user perspective) were - inserted into an object header and certain other conditions were - met. QAK - 2003/10/08 - - Changed implementation of internal ID searching algorithm to avoid - O(n) behavior for many common cases. QAK - 2003/10/06 - - Allow partial parallel writing to compact datasets.

We haven't found these problems on other - MPI-IO compilers. If you encounter these problems, you may use Independent IO - instead. - - Change the following line in your code: - H5Pset_dxpl_mpio(xfer_plist, H5FD_MPIO_COLLECTIVE); - - to - H5Pset_dxpl_mpio(xfer_plist, H5FD_MPIO_INDEPENDENT); - - KY - 2007/08/24 - -* For SNL, spirit/liberty/thunderbird: The serial tests pass but parallel - tests failed with MPI-IO file locking message. AKC - 2007/6/25. -* On Intel 64 Linux cluster (RH 4, Linux 2.6.9) with Intel 10.0 compilers use - -mp -O1 compilation flags to build the libraries. Higher level of optimization - causes failures in several HDF5 library tests. -* For HPUX 11.23 many tools tests failed for 64-bit version when linked to the - shared libraries (tested for 1.8.0-beta2) -* For SNL, Red Storm: only paralle HDF5 is supported. The serial tests pass - and the parallel tests also pass with lots of non-fatal error messages. -* For LLNL, uP: both serial and parallel pass. Zeus: serial passes but - parallel fails with a known proglem in MPI. ubgl: serial passes but - parallel fails. -* on SUN 5.10 C++ test fails in the "Testing Shared Datatypes with Attributes" test -* configuring with --enable-debug=all produces compiler errors on most - platforms. Users who want to run HDF5 in debug mode should use - --enable-debug rather than --enable-debug=all to enable debugging - information on most modules. -* On Mac OS 10.4, test/dt_arith.c has some errors in conversion from long - double to (unsigned) long long and from (unsigned)long long to long double. -* On Altix SGI with Intel 9.0 testmeta.c would not compile with -O3 - optimization flag. -* On VAX, Scaleoffset filter isn't supported. The filter cannot be applied to - HDF5 data generated on VAX. Scaleoffset filter only supports IEEE standard - for floating-point data. -* On Cray X1, a lone colon on the command line of h5dump --xml (as in - the testh5dumpxml.sh script) is misinterpereted by the operating system - and causes an error. -* On mpich 1.2.5 and 1.2.6, we found that if more than two processes - contribute no IO and the application asks to do IO with collective, we found - that when using 4 processors, a simple collective write will be hung - sometimes. This can be verified with t_mpi test under testpar. -* On IRIX6.5, when C compiler version >7.4, the complicate MPI derived data type - code will work. However, the user should be aware to enlarge MPI_TYPE_MAX environment - variable to some certian value in order to use collective irregular selection code. - For example, the current parallel HDF5 test needs to enlarge MPI_TYPE_MAX to - 200,000 to make the test pass. -* The dataset created or rewritten with the v1.6.3 library or after can't - be read with the v1.6.2 library or before when Fletcher32 EDC(filter) is - enabled. There was a bug in the calculating code of the Fletcher32 - checksum in the library before v1.6.3. The checksum value wasn't consistent - between big-endian and little-endian systems. This bug was fixed in - Release 1.6.3. However, after fixing the bug, the checksum value is no - longer the same as before on little-endian system. The library release - after 1.6.4 can still read the dataset created or rewritten with the library - of v1.6.2 or before. SLU - 2005/6/30 -* For the version 6(6.02 and 6.04) of Portland Group compiler on AMD Opteron - processor, there's a bug in the compiler for optimization(-O2). The library - failed in several tests but all related to multi driver. The problem has - been reported to the vendor. -* On IBM AIX systems, parallel HDF5 mode will fail some tests with error - messages like "INFO: 0031-XXX ...". This is from the command poe. - Set the environment variable MP_INFOLEVEL to 0 to minimize the messages - and run the tests again. - The tests may fail with messages like "The socket name is already - in use". HDF5 does not use sockets (except for stream-VFD). This is - due to problems of the poe command trying to set up the debug socket. - Check if there are many old /tmp/s.pedb.* staying around. These are - sockets used by the poe command and left behind due to failed commands. - Ask your system administrator to clean them out. Lastly, request IBM - to provide a mean to run poe without the debug socket. - -* The C++ library's tests fails when compiling with PGI C++ compiler. The - workaround until the problem is correctly handled is to use the - flag "--instantiate=local" prior to the configure and build steps, as: - setenv CXX "pgCC --instantiate=local" for pgCC 5.02 and higher - - -* The stream-vfd test uses ip port 10007 for testing. If another - application is already using that port address, the test will hang - indefinitely and has to be terminated by the kill command. To try the - test again, change the port address in test/stream_test.c to one not - being used in the host. - -* The --enable-static-exec configure flag fails to compile for Solaris - platforms. This is due to the fact that not all of the system - libraries on Solaris are available in a static format. - - The --enable-static-exec configure flag also fails to correctly compile - on IBM SP2 platform for the serial mode. The parallel mode works fine - with this option. - - It is suggested that you don't use this option on these platforms - during configuration. - -* With the gcc 2.95.2 compiler, HDF 5 uses the `-ansi' flag during - compilation. The ANSI version of the compiler complains about not being - able to handle the `long long' datatype with the warning: - - warning: ANSI C does not support `long long' - - This warning is innocuous and can be safely ignored. - - -* The Stream VFD was not tested yet under Windows. It is not supported - in the TFLOPS machine. - - -* The ./dsets tests failed in the TFLOPS machine if the test program, - dsets.c, is compiled with the -O option. The hdf5 library still works - correctly with the -O option. The test program works fine if it is - compiled with -O1 or -O0. Only -O (same as -O2) causes the test - program to fail. - -* Certain platforms give false negatives when testing h5ls: - - Cray J90 and Cray T90IEEE give errors during testing when displaying - some floating-point values. These are benign differences due to - the different precision in the values displayed and h5ls appears to - be dumping floating-point numbers correctly. - -* Before building HDF5 F90 Library from source on Crays - replace H5Aff.f90, H5Dff.f90 and H5Pff.f90 files in the fortran/src - subdirectory in the top level directory with the Cray-specific files - from this site: - ftp://www.hdfgroup.uiuc.edu/pub/outgoing/hdf5/hdf5-1.8.0-pre/PATCH/ - -* Not all platforms behave correctly with szip's shared libraries. Szip is - disabled in these cases, and a message is relayed at configure time. Static - libraries should be working on all systems that support szip, and should be - used when shared libraries are unavailable. There is also a configure error - on Altix machines that incorrectly reports when a version of szip without - an encoder is being used. - -* On some platforms that use Intel and Absoft compilers to build HDF5 fortran library, - compilation may fail for fortranlib_test.f90, fflush1.f90 and fflush2.f90 - complaining about exit subroutine. Comment out the line - IF (total_error .ne. 0) CALL exit (total_error) - -* On IA32 and IA64 systems, if you use a compiler other than GCC (such as - Intel's ecc or icc compilers), you will need to modify the generated - "libtool" program after configuration is finished. On or around line 104 of - the libtool file, there are lines which look like: - - # How to pass a linker flag through the compiler. - wl="" - - change these lines to this: - - # How to pass a linker flag through the compiler. - wl="-Wl," - - UPDATE: This is now done automatically by the configure script. However, if - you still experience a problem, you may want to check this line in the - libtool file and make sure that it has the correct value. - -* Information about building with PGI and Intel compilers is available in - INSTALL file sections 5.7 and 5.8 - -* On at least one system, (SDSC DataStar), the scheduler (in this case - LoadLeveler) sends job status updates to standard error when you run - any executable that was compiled with the parallel compilers. - - This causes problems when running "make check" on parallel builds, as - many of the tool tests function by saving the output from test runs, - and comparing it to an exemplar. - - The best solution is to reconfigure the target system so it no longer - inserts the extra text. However, this may not be practical. - - In such cases, one solution is to "setenv HDF5_Make_Ignore yes" prior to - the configure and build. This will cause "make check" to continue after - detecting errors in the tool tests. However, in the case of SDSC DataStar, - it also leaves you with some 150 "failed" tests to examine by hand. - - A second solution is to write a script to run serial tests and filter - out the text added by the scheduler. A sample script used on SDSC - DataStar is given below, but you will probably have to customize it - for your installation. - - Observe that the basic idea is to insert the script as the first item - on the command line which executes the the test. The script then - executes the test and filters out the offending text before passing - it on. - - #!/bin/csh - - set STDOUT_FILE=~/bin/serial_filter.stdout - set STDERR_FILE=~/bin/serial_filter.stderr - - rm -f $STDOUT_FILE $STDERR_FILE - - ($* > $STDOUT_FILE) >& $STDERR_FILE - - set RETURN_VALUE=$status - - cat $STDOUT_FILE - - tail +3 $STDERR_FILE - - exit $RETURN_VALUE - - You get the HDF make files and test scipts to execute your filter script - by setting the environment variable "RUNSERIAL" to the full path of the - script prior to running configure for parallel builds. Remember to - "unsetenv RUNSERIAL" before running configure for a serial build. - - Note that the RUNSERIAL environment variable exists so that we can - can prefix serial runs as necessary on the target system. On DataStar, - no prefix is necessary. However on an MPICH system, the prefix might - have to be set to something like "/usr/local/mpi/bin/mpirun -np 1" to - get the serial tests to run at all. - - In such cases, you will have to include the regular prefix in your - filter script. - -* H5Ocopy() does not copy reg_ref attributes correctly when shared-message - is turn on. The value of the reference in the destination attriubte is - wrong. This H5Ocopy problem will affect h5copy tool - -%%%%1.6.7%%%% Release Information for hdf5-1.6.7 (31/January/08) - -HDF5 version 1.6.7 released on Thu Jan 31 21:09:10 CST 2008 -================================================================================ - -INTRODUCTION -============ -This document describes the differences between HDF5-1.6.6 and HDF5-1.6.7 -It contains information on the platforms tested and known problems in -HDF5-1.6.7.

Unless otherwise noted, -compilers used are the system compilers. - -Footnotes: -(1) Fortran compiled with g95. - - -Known Problems -============== -* We discovered two problems when running collective IO parallel HDF5 tests - with chunking storage with the ChaMPIon MPI compiler on tungsten, a Linux - cluster at NCSA. - Under some complex selection cases, - 1) MPI_Get_element returns the wrong value. - 2) MPI_Type_struct also generates the wrong derived datatype and corrupt - data may be generated. - This only happens when turning on collective IO with chunking storage - with some complex selections. We haven't found these problems on other - MPI-IO compilers. If you encounter these problems, you may use Independent - IO instead. - - To avoid this problem, change the following line in your code: - H5Pset_dxpl_mpio(xfer_plist, H5FD_MPIO_COLLECTIVE); - - to - H5Pset_dxpl_mpio(xfer_plist, H5FD_MPIO_INDEPENDENT); - - KY - 2007/08/24 - -* QSC (an HP alpha-based OSF1 cluster) does not create h5pfc correctly. It - does not include the -lmpi properly. This will be fixed in the next - release. AKC - 2007/08/07. - -* On IRIX64 6.5 (UCAR SGI mop1), when testing HDF5 tools with an HDF5 shared - library, especially for h5repacktst and h52gifgentst, the following (or a - similar) error message may appear: - "523648:lt-h5repacktst: rld: Fatal Error: Cannot Successfully map soname - 'libh5test.so.1' under any of the filenames .......(bunch of directories) - " - And the testing will fail. - - We believe this is a libtool problem. One way to get rid of this is to - add the paths of libh5test.so.1 and libh5.so.1 to the shared library path. - - For 32-bit: - You may do this, under csh: - setenv LD_LIBRARYN32_PATH .......(existing paths):[full path of HDF5 - directory/test/.libs]:[full path of HDF5 directory/src/.libs] - - For 64-bit: - setenv LD_LIBRARY64_PATH ......(existing paths):[full path of HDF5 - directory/test/.libs]:[full path of HDF5 directory/src/.libs] - - NOTE: This problem ONLY affects the testing of the HDF5 library when you - build from source. It won't affect any applications that would like to link - with the HDF5 shared library since the shared library path needs to be set - anyway. KY - 2007/8/2 - -* QSC (an HP alpha-based OSF1 cluster) failed the testpar/testphdf5 sub-test - "calloc". All other tests passed. This indicates that a dataset using - chunked storage created by serial HDF5 may not work properly with parallel - HDF5. The calloc test can be skipped by running "prun ... testphdf5 -x - calloc". AKC - 2007/7/12. - -* The Intel C Compiler for the Linux x86_64 platform (EM64T-based, v8.1) has - an optimization error in the datatypes conversion code. Before running - configure, edit the file config/intel-flags by changing the setting of - PROD_CFLAGS from -O3 to -O0. Then run configure. AKC - 2005/11/10. - -* When testing parallel HDF5 with the C compiler version MIPSpro 7.4.3 on IRIX - 6.5, set the environment variable MPI_TYPE_MAX to be a bigger number, for - example 120000, in order to pass the complicated collective IO tests inside - the parallel HDF5 library. This is not a problem inside the parallel HDF5 - library. You can always set a bigger number on your system. KY - 2005/10/6 - -* A contiguous or chunked dataset created by a sequential version of HDF5 - might not be able to be modified with a parallel version of the library. - Use the H5Pset_alloc_time function with H5D_ALLOC_TIME_EARLY to set up the - dataset creation property list to avoid the problem. EIP - 2005/09/09 - -* A dataset created or rewritten with the v1.6.3 library or after can't - be read with the v1.6.2 library or before when Fletcher32 EDC (a filter) is - enabled. There was a bug in the calculating code of the Fletcher32 - checksum in the library before v1.6.3. The checksum value wasn't consistent - between big-endian and little-endian systems. This bug was fixed in - Release 1.6.3. However, after fixing the bug, the checksum value is no - longer the same as before on little-endian system. HDF5 library releases - after 1.6.4 can still read datasets created or rewritten with an HDF5 - library of v1.6.2 or before. SLU - 2005/7/8 - -* For version 6 (6.02 and 6.04) of the Portland Group compiler on AMD Opteron - processor, there's a bug in the compiler for optimization(-O2). The library - failed in several tests, all related to the multi driver. The problem has - been reported to the vendor. - -* test/big fails sometimes with the message "Possible overlap with another - region." The test selects regions randomly, and this error occurs when - two regions overlap each other; it is a bug in the test and not in - HDF5. Since the error is triggered by a random situation, it will - usually disappear if the test is re-run. - -* Newer SGI MIPSpro compilers (version 7.4.x) support C99 features but - have a "guard" statement in stdint.h that will #error and skip the rest - of the header file if the C99 option is not used explicitly. Hardsetting - $CC to c99 will resolve the problem. AKC - 2004/12/13 - -* On IBM AIX systems, parallel HDF5 mode will fail some tests with error - messages like "INFO: 0031-XXX ...". This is from the command poe. - Set the environment variable MP_INFOLEVEL to 0 to minimize the messages - and run the tests again. - - The tests may also fail with messages like "The socket name is already - in use". HDF5 does not use sockets. This is due to problems of the - poe command trying to set up the debug socket. Check whether there are - many old /tmp/s.pedb.* files staying around. These are sockets used by - the poe command and left behind due to failed commands. Ask your system - administrator to clean them out. Lastly, request IBM to provide a means - to run poe without the debug socket. - -* The h5dump tests may fail to match the expected output on some platforms - (e.g. parallel jobs, Windows) where the error messages directed to - "stderr" do not appear in the "right order" with output from stdout. - This is not an error. - -* The --enable-static-exec configure flag fails to compile for Solaris - platforms. This is due to the fact that not all of the system - libraries on Solaris are available in a static format. - - The --enable-static-exec configure flag also fails to correctly compile - on the IBM SP2 platform for the serial mode. The parallel mode works fine - with this option. - - The --enable-static-exec configure flag also fails to correctly compile - on the HPUX 11.00. - - It is suggested that you don't use this option on these platforms - during configuration. - -* Use the --disable-shared configure flag if building with an Absoft Fortran - compiler. - -* Information about building with PGI and Intel compilers is available in - INSTALL file sections 5.7 and 5.8. - -* In LANL QSC, the new cc compiler has problems converting small values of - long long (absolute values less than 1**-308) to double. This triggers - the test/dtypes to report failure in the following test: - Testing random sw long double -> double conversions - If -ieee is used, the converted doubles spread over the range 0.0 to - 10**-308. If -ieee is not used, the converted double values are mostly - 0.0, but occasionally appear as 10**-308. This has been reported to the - system staff. - - All other tests have passed. - -* On at least one system, SDSC DataStar, the scheduler (in this case - LoadLeveler) sends job status updates to standard error when you run - any executable that was compiled with the parallel compilers. - - This causes problems when running "make check" on parallel builds, as - many of the tool tests function by saving the output from test runs, - and comparing it to an exemplar. - - The best solution is to reconfigure the target system so it no longer - inserts the extra text. However, this may not be practical. - - In such cases, one solution is to "setenv HDF5_Make_Ignore yes" prior to - the configure and build. This will cause "make check" to continue after - detecting errors in the tool tests. However, in the case of SDSC DataStar, - it also leaves you with some 150 "failed" tests to examine by hand. - - A second solution is to write a script to run serial tests and filter - out the text added by the scheduler. A sample script used on SDSC - DataStar is given below, but you will probably have to customize it - for your installation. - - Observe that the basic idea is to insert the script as the first item - on the command line which executes the test. The script then - executes the test and filters out the offending text before passing - it on. - - #!/bin/csh - - set STDOUT_FILE=~/bin/serial_filter.stdout - set STDERR_FILE=~/bin/serial_filter.stderr - - rm -f $STDOUT_FILE $STDERR_FILE - - ($* > $STDOUT_FILE) >& $STDERR_FILE - - set RETURN_VALUE=$status - - cat $STDOUT_FILE - - tail +3 $STDERR_FILE - - exit $RETURN_VALUE - - You get the HDF5 make files and test scripts to execute your filter script - by setting the environment variable "RUNSERIAL" to the full path of the - script prior to running configure for parallel builds. Remember to - "unsetenv RUNSERIAL" before running configure for a serial build. - - Note that the RUNSERIAL environment variable exists so that we can - prefix serial runs as necessary on the target system. On DataStar, - no prefix is necessary. However, on an MPICH system, the prefix might - have to be set to something like "/usr/local/mpi/bin/mpirun -np 1" to - get the serial tests to run at all. - - In such cases, you will have to include the regular prefix in your - filter script.

QAK - -2007/06/19 - - STDIO driver didn't support files bigger than 2GB because the OFFSET - parameter of fseek is of type LONG INT, not big enough for big - files. Use fseeko instead for big files if it's available on the - system. SLU - 2007/4/5 - - Relaxed restrictions on attribute operations to allow a file ID to - be used as the "location ID". If a file ID is used, the attribute - operation will occur on the root group of the file. - QAK - 2007/02/09 - - Fixed a bug in H5Sselect_valid() that caused an incorrect value to - be returned (0) instead of FAIL on error conditions such as the - selection or extent not being defined. CMC - 2007/01/05 - - Fixed potential file corruption bug which could overwrite a portion - of an object's header when an attribute was renamed. If the new - name for the attribute was longer than the old name, it was -possible - that the attribute would grow enough to overwrite another message - in the object's header. QAK - 2007/01/02 - - Fixed file corruption bug which could write an incorrect number of - messages to an object's header under certain circumstances. - Generally, the sequence of actions to generate this bug looks - like this: - - Create an object. - - Close the file. - - Re-open the file. - - Add 2 (or more) attributes to the object. - - Close the file. - - Re-open the file. - - Delete one of the attributes on the object. - - Add a smaller attribute to the object. - - Delete the smaller atttribute on the object. - - Add a larger attribute on the object. - - After this, the number of header messages stored for the object - will be off by one. Other sequences of modifying attributes on an - object could also trigger this bug. If you are opening an - object and the bottom few messages of the HDF5 error stack - resembles the following, the object has been affected by this bug: - - #007: ../../hdf5_v1.6/src/H5C.c line 3887 in H5C_load_entry(): -unable to load entry - major(08): Meta data cache layer - minor(40): Unable to load metadata into cache - #008: ../../hdf5_v1.6/src/H5Ocache.c line 332 in H5O_load(): -corrupt object header - too few messages - major(12): Object header layer - minor(40): Unable to load metadata into cache - - Specifically, "corrupt object header" is the best string to search - for in the HDF5 error stack output. - - If your files have been affected by this bug, or you are concerned - that your files might have been, please contact the HDF Helpdesk - at help@hdfgroup.org for a tool to detect and repair files - affected by this problem. QAK - 2006/6/16 - - - Fixed various problems with retrieving names of objects, especially - with mounted files. QAK - 2005/12/25 - - Configuration - ------------- - - Changed to default to --disable-shared if parallel is enabled. - AKC - 2007/5/12 - - Corrected a coding error in configure when it tries to locate the - needed MPI and MPI-IO library for the fortran interface. - AKC - 007/5/9. - - Changed default fortran compiler to g95 when gcc is used. - AKC - 007/2/17. - - Configure can now use any tr command. No more need for - defining the variable TR, nor is it supported. AKC - 2006/05/20 - - Performance - ------------- - - None - - Tools - ----- - - Fixed a bug in h5dump regarding the display of named datatypes - attributes. PVN - 2007/03/13 - - Fixed a bug in h5dump regarding the display of group comments. - PVN - 2007/03/13 - - Fixed a bug in h5dump regarding the display of hardlinks pointing - to the root group. PVN - 2007/03/13 - - Fixed a bug in the h5diff percentage option -p. PVN - 2007/03/05 - - Fixed a bug in h5dump that caused array indices greater than 2^32-1 - not to be printed correctly.

It - does not include the -lmpi properly. This will be fixed in the next - release. AKC - 2007/08/07. - -* On IRIX64 6.5 (UCAR SGI mop1), when testing HDF5 tools with an HDF5 shared - library, especially for h5repacktst and h52gifgentst, the following (or - similar) error message may appear: - "523648:lt-h5repacktst: rld: Fatal Error: Cannot Successfully map soname - 'libh5test.so.1' under any of the filenames .......(bunch of directories) - " - And the testing will fail. - We believe this is a libtool problem. One way to get rid of this is to - add the paths of libh5test.so.1 and libh5.so.1 to the shared library path. - - For 32-bit: - You may do this, under csh: - setenv LD_LIBRARYN32_PATH .......(existing pathes):[full path of HDF5 - directory/test/.libs]:[full path of HDF5 directory/src/.libs] - - For 64-bit: - setenv LD_LIBRARY64_PATH ......(existing pathes):[full path of HDF5 - directory/test/.libs]:[full path of HDF5 directory/src/.libs] - - NOTE: This problem ONLY affects the testing of the HDF5 library when you - build from source. It won't affect any applications that would like to link - with the HDF5 shared library since the shared library path needs to be set - anyway. KY - 2007/8/2 - -* QSC (an HP alpha-based OSF1 cluster) failed the testpar/testphdf5 sub-test - "calloc". All other tests passed. This indicates that a dataset using - chunked storage created by serial HDF5 may not work properly with parallel - HDF5. The calloc test can be skipped by running "prun ... testphdf5 -x - calloc". AKC - 2007/7/12. - -* The Intel C Compiler for the Linux x86_64 platform (EM64T-based, v8.1) has - an optimization error in the datax types conversion code. Before running - configure, edit the file config/intel-flags by changing the setting of - PROD_CFLAGS from -O3 to -O0. Then run configure. AKC - 2005/11/10. - -* When testing parallel HDF5 with the C compiler version MIPSpro 7.4.3 on IRIX - 6.5, set the environment variable MPI_TYPE_MAX to be a bigger number, for - example 120000, in order to pass the complicated collective IO tests inside - the parallel HDF5 library. This is not a problem inside the parallel HDF5 - library. You can always set a bigger number on your system. KY - 2005/10/6 - -* A contiguous or chunked dataset created by a sequential version of HDF5 - might not be able to be modified with a parallel version of the library. - Use the H5Pset_alloc_time function with H5D_ALLOC_TIME_EARLY to set up the - dataset creation property list to avoid the problem. EIP - 2005/09/09 - -* The dataset created or rewritten with the v1.6.3 library or after can't - be read with the v1.6.2 library or before when Fletcher32 EDC (a filter) is - enabled. There was a bug in the calculating code of the Fletcher32 - checksum in the library before v1.6.3. The checksum value wasn't consistent - between big-endian and little-endian systems. This bug was fixed in - Release 1.6.3. However, after fixing the bug, the checksum value is no - longer the same as before on little-endian system. The library release - after 1.6.4 can still read the dataset created or rewritten with the library - of v1.6.2 or before. SLU - 2005/7/8 - -* For version 6 (6.02 and 6.04) of the Portland Group compiler on AMD Opteron - processor, there's a bug in the compiler for optimization(-O2). The library - failed in several tests, all related to the multi driver. The problem has - been reported to the vendor. - -* test/big fails sometimes with the message "Possible overlap with another - region." The test selects regions randomly, and this error occurs when - two regions overlap each other; it is a bug in the test and not in - HDF5. Since the error is triggered by a random situation, it will - usually disappear if the test is re-run. - -* Newer SGI MIPSpro compilers (version 7.4.x) support C99 features but - have a "guard" statement in stdint.h that will #error and skip the rest - of the header file if the C99 option is not used explicitly. Hardsetting - $CC to c99 will resolve the problem. AKC - 2004/12/13 - -* On IBM AIX systems, parallel HDF5 mode will fail some tests with error - messages like "INFO: 0031-XXX ...". This is from the command poe. - Set the environment variable MP_INFOLEVEL to 0 to minimize the messages - and run the tests again. - - The tests may also fail with messages like "The socket name is already - in use". HDF5 does not use sockets (except for stream-VFD). This is - due to problems of the poe command trying to set up the debug socket. - Check whether there are many old /tmp/s.pedb.* files staying around. These - are sockets used by the poe command and left behind due to failed commands. - Ask your system administrator to clean them out. Lastly, request IBM - to provide a means to run poe without the debug socket. - -* The h5dump tests may fail to match the expected output on some platforms - (e.g. parallel jobs, Windows) where the error messages directed to - "stderr" do not appear in the "right order" with output from stdout. - This is not an error. - -* The stream-vfd test uses ip port 10007 for testing. If another - application is already using that port address, the test will hang - indefinitely and has to be terminated by the kill command. To try the - test again, change the port address in test/stream_test.c to one not - being used in the host. - -* The --enable-static-exec configure flag fails to compile for Solaris - platforms. This is due to the fact that not all of the system - libraries on Solaris are available in a static format. - - The --enable-static-exec configure flag also fails to correctly compile - on the IBM SP2 platform for the serial mode. The parallel mode works fine - with this option. - - The --enable-static-exec configure flag also fails to correctly compile - on the HPUX 11.00. - - It is suggested that you don't use this option on these platforms - during configuration. - -* The Stream VFD is not supported under Windows. - -* Use the --disable-shared configure flag if building with Absoft Fortran - compiler. - -* Information about building with PGI and Intel compilers is available in - INSTALL file sections 5.7 and 5.8. - -* In LANL QSC, the new cc compiler has problems converting small values of - long long (absolute values less than 1**-308) to double. This triggers - the test/dtypes to report failure in the following test: - Testing random sw long double -> double conversions - If -ieee is used, the converted doubles spread over the range 0.0 to - 10**-308. If -ieee is not used, the converted double values are mostly - 0.0, but occasionally appear as 10**-308. This has been reported to the - system staff. - - All other tests have passed. - -* On at least one system, SDSC DataStar, the scheduler (in this case - LoadLeveler) sends job status updates to standard error when you run - any executable that was compiled with the parallel compilers. - - This causes problems when running "make check" on parallel builds, as - many of the tool tests function by saving the output from test runs, - and comparing it to an exemplar. - - The best solution is to reconfigure the target system so it no longer - inserts the extra text. However, this may not be practical. - - In such cases, one solution is to "setenv HDF5_Make_Ignore yes" prior to - the configure and build. This will cause "make check" to continue after - detecting errors in the tool tests. However, in the case of SDSC DataStar, - it also leaves you with some 150 "failed" tests to examine by hand. - - A second solution is to write a script to run serial tests and filter - out the text added by the scheduler. A sample script used on SDSC - DataStar is given below, but you will probably have to customize it - for your installation. - - Observe that the basic idea is to insert the script as the first item - on the command line which executes the test. The script then - executes the test and filters out the offending text before passing - it on. - - #!/bin/csh - - set STDOUT_FILE=~/bin/serial_filter.stdout - set STDERR_FILE=~/bin/serial_filter.stderr - - rm -f $STDOUT_FILE $STDERR_FILE - - ($* > $STDOUT_FILE) >& $STDERR_FILE - - set RETURN_VALUE=$status - - cat $STDOUT_FILE - - tail +3 $STDERR_FILE - - exit $RETURN_VALUE - - You get the HDF5 make files and test scripts to execute your filter script - by setting the environment variable "RUNSERIAL" to the full path of the - script prior to running configure for parallel builds. Remember to - "unsetenv RUNSERIAL" before running configure for a serial build. - - Note that the RUNSERIAL environment variable exists so that we can - prefix serial runs as necessary on the target system. On DataStar, - no prefix is necessary. However, on an MPICH system, the prefix might - have to be set to something like "/usr/local/mpi/bin/mpirun -np 1" to - get the serial tests to run at all. - - In such cases, you will have to include the regular prefix in your - filter script.

AKC - 2005/11/10 - - Configure now recognizes the TR variable as the location of the - tr utility. JML 2005/10/20 - - Source code distribution: - ------------------------- - - Added g95 as a testing "platform" informally. AKC - 2005/10/04. - - Added MD5 checksumming to snapshot releases. Releases will now - produce an .md5 file as well as a .tar archive. md5sum can be - used to verify the arvhice with the .md5 checksum. -JL 2005/09/06 - - Library: - -------- - - Added HSYS_ERROR which retrieves the system error message and pushes - it to the error stack. This provides more information regarding the - failed system call. AKC - 2005/08/04 - - Added H5F_OBJ_LOCAL flag to H5Fget_obj_count() & H5Fget_obj_ids(), to - allow querying for objects in a file that was opened with a particular - file ID, instead of all objects opened in the file with any file ID. - QAK - 2005/06/01 - - Parallel Library: - ----------------- - - Added mpich2 as a testing "platform" informally. AKC - 2005/10/04. - - HDF5 supports collective MPI-IO for irregular selection with HDF5 - dataset. Irregular selection is when users use API H5Sselect_hyperslab - more than once for the same dataset. - Currently, not all MPI-IO packages support the complicated - MPI derived datatypes used in the implementation of irregular - selections INSIDE HDF5. - 1) DEC 5.x wdoes not support complicated derived datatypes. - 2) For AIX 5.1: - If your poe version number is 3.2.0.20 or lower, - please edit powerpc-ibm-aix5.x in the directory hdf5/config/. - Find the line with - << hdf5_mpi_complex_derived_datatype_works >> - and UNCOMMENT this line before the configure. - check poe version with the following command: - lpp -l all | grep ppe.poe - 3) For Linux cluster,: - If mpich version is 1.2.5 or lower, collective irregular selection - IO is not supported; internally independent IO is used. - 4) For IRIX 6.5: - if C compiler version is 7.3 or lower, collective irregular - selection IO is not supported; internally independent IO is used. - 5) For platforms which internally used mpich: - If the mpich version is 1.2.5 or lower, please find the - corresponding config (in hdf5/config) file and add - hdf5_mpi_complex_derived_datatype_works='no' - at the end of the configuration file. For example, on the - NCSA SGI Altix, the internal mpich library is 1.2.5. So - hdf5_mpi_complex_derived_datatype_works='no' - should be added at the end of the config file ia64-linux-gnu. - KY - 2005/09/12 - - Tools: - ------ - - Removed obsolete pdb2hdf tool. JML - 2005/10/28 - - Sped up h5dump on files with large numbers of objects. - QAK - 2005/08/25 - - F90 API: - -------- - - Added missing h5tget_member_class_f function - EIP 2005/04/06 - C++ API: - -------- - - Added missing member functions: - H5::CompType::getMemberArrayType - H5::CompType::getMemberVarLenType - H5::AbstractDs::getArrayType - H5::AbstractDs::getVarLenType - H5::CommonFG::openArrayType - H5::CommonFG::openVarLenType - H5::PropList::copyProp -- this will replace the current - H5::PropList::copyProp in later releases due - to incorrect prototype. - BMR - 2005/07/27 - - -Support for New Platforms, Languages and Compilers -================================================== - - Added support for RedStorm platform (serial only.) AKC 2005/11/10 - - Added support for BG/L platform (serial only.) LA 2005/11/10 - - Added support for HPUX 11.23 (IA64); only C and C++ are supported - with the +DD64 flag - EIP 2005/10/05 - - - Configuration - ------------- - - Added support for Cray X1. JML 2005/10/03 - - -Bug Fixes since HDF5-1.6.4 Release -================================== - - Library - ------- - - Fixed collective IO in chunking-storage. HDF5 may have called the - wrong routine when the shape of the dataspace in the file and in - the bufferred chunk were different. This bug was fixed to make sure - the correct routine is called. KY - 2005/10/19 - - Fixed core dump when closing root groups opened through two different - file handles that operate on the same actual file. QAK - 2005/10/02 - - The ./dsets tests used to fail in the TFLOPS machine if the - test program, dsets.c, was compiled with the -O option. - The HDF5 library still worked correctly with the -O option. Only - the ./dsets failed. It is fixed. AKC - 2005/09/14 - - Corrected errors when performing various operations on a group opened - by dereferencing an object reference. QAK - 2005/07/30 - - Fixed a bug with named datatypes where a copy of a named datatype - used to create a dataset would accidentally use the original - named datatype for the dataset's datatype. QAK - 2005/07/23 - - Made H5Fget_name() to be consistent and always return name of actual - file the ID is in. (Instead of the name of the top file in a - file mounting hierarchy). QAK - 2005/07/19 - - Reworked internal file mounting semantics to hopefully eliminate - mounting problems. We now require that files that are mounting - together all have the same "file close degree". QAK - 2005/07/19 - - More bug fixes on holding open files that are mounted and have - IDs open. QAK - 2005/07/14 - - Dataset sieve buffer cache was inadvertantly disabled; it has been - re-enabled. QAK - 2005/07/08 - - Don't unmount child files until the parent file actually closes. - (Previously, if an object was holding open a file, the child files - would get unmounted too early). QAK - 2005/07/05 - - Fixed bug where unmounted files could cause the library to go into - an infinite loop when shutting down. QAK - 2005/06/30 - - Fixed bug with hyperslab selections that use selection offsets and - operate on chunked datasets going into infinite loop or dumping - core. QAK - 2005/06/17 - - Corrected memory leak and possible corruption when opening a group. - QAK - 2005/06/17 - - Added check for opaque datatype tags being too long (check against - H5T_OPAQUE_TAG_MAX, currently set to 256). QAK - 2005/06/14 - - Fixed various errors in maintaining names for open objects in the - face of unusual mount & unmount operations. QAK - 2005/06/08 - - "SEMI" and "STRONG" file close degree settings now apply only to the - particular file ID being closed, instead of operating on all open - file IDs for a given file. QAK - 2005/06/01 - - Fixed error in opening object in a group that was opened in a mounted - file which has been unmounted. QAK - 2005/03/17 - - Configuration - ------------- - - Configure can recognize -lmpich as a form of MPI library. -AKC- - 2005/9/28. - - Changed default C++ compiler for the IA64 platform from icc to - icpc which is the preferred compiler for Intel Compiler version - 8. AKC - 2005/09/02 - - Performance - ------------- - - Optimized I/O for enumerated datatypes that are a superset of a - source enumerated datatype.

Before running - configure, edit the file config/intel-flags by changing the setting of - PROD_CFLAGS from -O3 to -O0, then run configure. AKC - 2005/11/10. - -* Fortran testing and compiling failures on windows XP - 1. Compaq visual fortran 6.6c with VS 6.0 - The Fortran tests failed for both release, release dll, debug and debug - dll. The failure is a random one. We won't provide fortran libraries. The - same test passed with the 1.7.51 snapshot. You may find the 1.7.51 - snapshot under ftp://hdf.ncsa.uiuc.edu/pub/outgoing/hdf5/snapshots/. - 2. Intel fortran 8.1 under .Net environment - The fortran library cannot even be compiled. Some users have pointed this - to intel forum. - -* When testing parallel HDF5 with the C compiler version MIPSpro 7.4.3 at IRIX - 6.5, set enviroment variable MPI_TYPE_MAX to be a bigger number, for example - 120000, in order to pass the complicated collective IO tests inside parallel - HDF5 library. This is not a problem inside parallel HDF5 library. You can - always set a bigger number in your system. - KY - 2005/10/6 - -* A contiguous or chunked dataset created by a sequential version may - not be modified with a parallel version of the library. - Use the H5Pset_alloc_time function with H5D_ALLOC_TIME_EARLY to set up the - dataset creation property list to avoid the problem. - EIP - 2005/09/09 - -* The dataset created or rewritten with the v1.6.3 library or after can't - be read with the v1.6.2 library or before when Fletcher32 EDC(filter) is - enabled. There was a bug in the calculating code of the Fletcher32 - checksum in the library before v1.6.3. The checksum value wasn't consistent - between big-endian and little-endian systems. This bug was fixed in - Release 1.6.3. However, after fixing the bug, the checksum value is no - longer the same as before on little-endian system. The library release - after 1.6.4 can still read the dataset created or rewritten with the library - of v1.6.2 or before. SLU - 2005/7/8 - -* For version 6 (6.02 and 6.04) of the Portland Group compiler on AMD Opteron - processor, there's a bug in the compiler for optimization(-O2). The library - failed in several tests but all related to multi driver. The problem has - been reported to the vendor. - -* test/big fails sometimes with the message "Possible overlap with another - region." The test selects regions randomly, and this error occurs when - two regions overlap each other; it is a bug in the test and not in - HDF5. Since the error is triggered by a random situation, it will - usually disappear if the test is re-run. - -* Newer SGI MIPSpro compilers (version 7.4.x) support C99 features but it - has a "guard" statement in stdint.h that will #error and skip the rest - of the header file if C99 option is not used explicitly. Hardset - $CC to c99 will resolve the problem. AKC - 2004/12/13 - -* On IBM AIX systems, parallel HDF5 mode will fail some tests with error - messages like "INFO: 0031-XXX ...". This is from the command poe. - Set the environment variable MP_INFOLEVEL to 0 to minimize the messages - and run the tests again. - The tests may fail with messages like "The socket name is already - in use". HDF5 does not use sockets (except for stream-VFD). This is - due to problems of the poe command trying to set up the debug socket. - Check if there are many old /tmp/s.pedb.* staying around. These are - sockets used by the poe command and left behind due to failed commands. - Ask your system administrator to clean them out. Lastly, request IBM - to provide a means to run poe without the debug socket. - -* Two h5dump xml tests(h5dump --xml thlink.h5 and h5dump --xml tmany.h5) - failed on windows xp with .NET for debug and debug dll. Release and - Release dll work fine. - -* The h5dump tests may fail to match the expected output on some platforms - (e.g. parallel jobs, Windows) where the error messages directed to - "stderr" do not appear in the "right order" with output from stdout. - This is not an error. - -* The stream-vfd test uses ip port 10007 for testing. If another - application is already using that port address, the test will hang - indefinitely and has to be terminated by the kill command. To try the - test again, change the port address in test/stream_test.c to one not - being used in the host. - -* The --enable-static-exec configure flag fails to compile for Solaris - platforms. This is due to the fact that not all of the system - libraries on Solaris are available in a static format. - - The --enable-static-exec configure flag also fails to correctly compile - on IBM SP2 platform for the serial mode. The parallel mode works fine - with this option. - - The --enable-static-exec configure flag also fails to correctly compile - on the HPUX 11.00. - - It is suggested that you don't use this option on these platforms - during configuration. - -* The Stream VFD was not tested yet under Windows. - - -* Before building HDF5 F90 Library from source on Crays - replace H5Aff.f90, H5Dff.f90 and H5Pff.f90 files in the fortran/src - subdirectory in the top level directory with the Cray-specific files - from the site: - ftp://ftp.ncsa.uiuc.edu/HDF/HDF5/current/src/patches/ - -* Use --disable-shared configure flag if building with Absoft Fortran - compiler. - -* Information about building with PGI and Intel compilers is available in - INSTALL file sections 5.7 and 5.8. - -* In LANL QSC, the new cc compiler has problems converting small values of - long long (absolute values less than 1**-308) to double. This triggers - the test/dtypes to report failure in the - Testing random sw long double -> double conversions - If -ieee is used, the converted doubles spread over the range 0.0 to 1**-308. - If -ieee is not used, the converted double values are mostly 0.0 but - occasionally as 1**-308. This has been reported to the system staff. - All other tests have passed. - -* Fortran release DLL randomly failed with Compaq Visual Fortran 6.6c on - Windows. - -* Fortran DLL built with Intel 8.1 in .NET environment crushed the compiler, - Building Fortran static library with Intel 8.1 in .NET environment - requires manually setting the project file. - Please contact to hdfhelp@ncsa.uiuc.edu if you need to build - Fortran static library with Intel 8.1 with .NET environment. - -* On at least one system, SDSC DataStar, the scheduler (in this case - LoadLeveler) sends job status updates to standard error when you run - any executable that was compiled with the parallel compilers. - - This causes problems when running "make check" on parallel builds, as - many of the tool tests function by saving the output from test runs, - and comparing it to an exemplar. - - The best solution is to reconfigure the target system so it no longer - inserts the extra text. However, this may not be practical. - - In such cases, one solution is to "setenv HDF5_Make_Ignore yes" prior to - the configure and build. This will cause "make check" to continue after - detecting errors in the tool tests. However, in the case of SDSC DataStar, - it also leaves you with some 150 "failed" tests to examine by hand. - - A second solution is to write a script to run serial tests and filter - out the text added by the scheduler. A sample script used on SDSC - DataStar is given below, but you will probably have to customize it - for your installation. - - Observe that the basic idea is to insert the script as the first item - on the command line which executes the test. The script then - executes the test and filters out the offending text before passing - it on. - - #!/bin/csh - - set STDOUT_FILE=~/bin/serial_filter.stdout - set STDERR_FILE=~/bin/serial_filter.stderr - - rm -f $STDOUT_FILE $STDERR_FILE - - ($* > $STDOUT_FILE) >& $STDERR_FILE - - set RETURN_VALUE=$status - - cat $STDOUT_FILE - - tail +3 $STDERR_FILE - - exit $RETURN_VALUE - - You get the HDF make files and test scripts to execute your filter script - by setting the environment variable "RUNSERIAL" to the full path of the - script prior to running configure for parallel builds. Remember to - "unsetenv RUNSERIAL" before running configure for a serial build. - - Note that the RUNSERIAL environment variable exists so that we can - prefix serial runs as necessary on the target system. On DataStar, - no prefix is necessary. However, on an MPICH system, the prefix might - have to be set to something like "/usr/local/mpi/bin/mpirun -np 1" to - get the serial tests to run at all. - - In such cases, you will have to include the regular prefix in your - filter script. - -%%%%1.6.4%%%% Release Information for hdf5-1.6.4 (15/March/05) - - -HDF5 version 1.6.4 released on Tue Mar 15 20:38:48 CST 2005 -================================================================================ - -INTRODUCTION -============ -This document describes the differences between HDF5-1.6.3 and -HDF5-1.6.4, and contains information on the platforms tested and -known problems in HDF5-1.6.4.

The size can be increased and decreased (without - cutting the last member). No API change is involved. SLU - - 2004/10/1 - - Removed PABLO support. 2005/01/20 EIP - - Parallel Library: - ----------------- - - Allow compressed, chunked datasets to be read in parallel. - QAK - 2004/10/04 - - Tools: - ------ - - New tool, h5jam. See HDF5 Reference Manual. 2004/10/08 - - F90 API: - -------- - No new features in this release. - - C++ API: - -------- - - Started using C library's reference counting in place of the class - RefCounter, which existed before the C mechanism was available. - As a result, RefCounter has been removed. 2005/03/12 BMR - - -Support for new platforms, languages and compilers. -======================================= - - Configuration - ------------- - - Upgraded from GNU autoconf 2.53 to autoconf 2.59. JML - 2005/01/31 - - -Bug Fixes since HDF5-1.6.3 release -================================== - - Library - ------- - - Fixed a racing condition in MPIPOSIX virtual file drive close - function. Now all processes must completed the close before any - of them is returned. This prevents some "faster" processes start - accessing the file for another purpose (e.g., open with truncate) - while other "slower" processes have not closed the same file with - the previous purpose. AKC - 2005/03/01 - - H5Tget_member_value calls for enum datatype didn't return correct - value if H5Tenum_valueof was called first. It's fixed. SLU - - 2005/02/08 - - For variable-length string, H5Tget_class returned H5T_STRING as its - class. But H5Tdetect_class and H5Tget_member_class considered it - as H5T_VLEN. This is fixed to let all these 3 functions treat it - as H5T_STRING. SLU - 2005/02/08 - - The byte order of all 1-byte integer types was fixed as - little-endian even on a big-endian machine. It's corrected. - SLU - 2005/02/07 - - Fixed segmentation fault when calling H5Fflush with an attribute that - hasn't had a value written to it open. QAK - 2004/10/18 - - Backed out support for bitfield and time types in H5Tget_native_type. - Leave it to future support. The function simply returns error - message of "not support" for bitfield and time types. SLU - 2004/10/5 - - Fixed address check in Core VFL driver to avoid spurious address/size - overflows for odd valued addresses and/or sizes. QAK - 2004/09/27 - - Fixed problem where chunked datasets were not able to be deleted - from a file under certain circumstances. QAK - 2004/09/27/ - - Configuration - ------------- - - IRIX64 MIPSpro compiler of 7.4.x supports C99 features. Default - to use the 'c99' compiler if available. AKC - 2004/12/13 - - Intel v8.0 compiler would infinite loop when compiling some test - code with -O3 option. Changed enable-production default compiler - option to -O2. AKC - 2004/12/06 - - Long double is assumed to be a supported C data type. It is a - standard C89 type. AKC - 2004/10/22 - - Performance - ------------- - Many changes were made to the library to improve performance, - especially for the variable-length datatypes and metadata cache. - - Tools - ----- - - h5fc and h5c++ work correctly when -c compiler flag - is used. EIP - 2005/03/14 - - Fixed h5dump to print attributes data in ASCII if -r option is used. - AKC - 2004/11/18 - - Fixed space utilization reported in h5ls to correct error - in formula used. QAK - 2004/10/22 - - Documentation - ------------- - - F90 API - ------- - - On windows, previously Fortran DLL built and tested failed. - Now Fortran DLL has been built and tested successfully - with Dec Fortran 6.6c or Dec Fortran 6.0. - - C++ API - ------- - - -Documentation -============= - - HDF5 Library documentation - -------------------------- - No substantive changes to the structure or types of content in the - HDF5 Library documentation. - - Windows installation documentation - ---------------------------------- - 1.

The test selects regions randomly, and this error occurs when - two regions overlap each other; it is an bug in the test and not in - HDF5. Since the error is triggered by a random situation, it will - usually disappear if the test is re-run. - -* Cray SV1 fails to correctly convert between floating-point and "long double" - for software conversion. Problem is being investigated. SLU - 2005/03/04 - -* Newer SGI MIPSpro compilers (version 7.4.x) support C99 features but it - has a "guard" statement in stdint.h that will #error and skip the rest - of the header file if C99 option is not used explicitly. Hardset - $CC to c99 will resolve the problem. AKC - 2004/12/13 - -* On IBM AIX systems, parallel HDF5 mode will fail some tests with error - messages like "INFO: 0031-XXX ...". This is from the command poe. - Set the environment variable MP_INFOLEVEL to 0 to minimize the messages - and run the tests again. - The tests may fail with messages like "The socket name is already - in use". HDF5 does not use sockets (except for stream-VFD). This is - due to problems of the poe command trying to set up the debug socket. - Check if there are many old /tmp/s.pedb.* staying around. These are - sockets used by the poe command and left behind due to failed commands. - Ask your system administrator to clean them out. Lastly, request IBM - to provide a mean to run poe without the debug socket. - -* Fortran subroutine h5pget_driver_f doesn't return a correct driver - information. - -* There are two h5dump xml tests(h5dump --xml thlink.h5 and - h5dump --xml tmany.h5) failed on windows xp with .NET for debug and - debug dll. Release and Release dll work fine. - -* The h5dump tests may fail to match the expected output on some platforms - (e.g. parallel jobs, Windows) where the error messages directed to - "stderr" do not appear in the "right order" with output from stdout. - This is not an error. - -* The stream-vfd test uses ip port 10007 for testing. If another - application is already using that port address, the test will hang - indefinitely and has to be terminated by the kill command. To try the - test again, change the port address in test/stream_test.c to one not - being used in the host. - -* The --enable-static-exec configure flag fails to compile for Solaris - platforms. This is due to the fact that not all of the system - libraries on Solaris are available in a static format. - - The --enable-static-exec configure flag also fails to correctly compile - on IBM SP2 platform for the serial mode. The parallel mode works fine - with this option. - - It is suggested that you don't use this option on these platforms - during configuration. - -* The Stream VFD was not tested yet under Windows. It is not supported - in the TFLOPS machine. - -* The ./dsets tests failed in the TFLOPS machine if the test program, - dsets.c, is compiled with the -O option. The hdf5 library still works - correctly with the -O option. The test program works fine if it is - compiled with -O1 or -O0. Only -O (same as -O2) causes the test - program to fail. - -* Certain platforms give false negatives when testing h5ls: - - Cray T90IEEE give errors during testing when displaying - some floating-point values. These are benign differences due to - the different precision in the values displayed. - h5ls appears to be dumping floating-point numbers correctly. - -* Before building HDF5 F90 Library from source on Crays - replace H5Aff.f90, H5Dff.f90 and H5Pff.f90 files in the fortran/src - subdirectory in the top level directory with the Cray-specific files - from the site: - ftp://ftp.ncsa.uiuc.edu/HDF/HDF5/current/src/patches/ - -* On some platforms that use Intel and Absoft compilers to build HDF5 fortran - library, compilation may fail for fortranlib_test.f90, fflush1.f90 and - fflush2.f90 complaining about exit subroutine. Comment out the line - IF (total_error .ne. 0) CALL exit (total_error) - -* Use --disable-shared configure flag if building with Absoft Fortran - compiler - -* Information about building with PGI and Intel compilers is available in - INSTALL file sections 5.7 and 5.8 - -* In LANL QSC, the new cc compiler has problems converting small values of - long long (absolute values less than 1**-308) to double. This triggers - the test/dtypes to report failure in the - Testing random sw long double -> double conversions - If -ieee is used, the converted doubles spread over the range 0.0 to 1**-308. - If -ieee is not used, the converted double values are mostly 0.0 but - occasionally as 1**-308. This has been reported to the system staff. - All other tests have passed. - -* The C++ library's tests fails when compiling with PGI C++ compiler. The - workaround until the problem is correctly handled is to use the - flag "--instantiate=local" prior to the configure and build steps, as: - setenv CXX "pgCC --instantiate=local" for pgCC 5.02 and higher - setenv CXX "pgCC -tlocal" for others - -* Fortran release DLL randomly failed with compaq visual fortran 6.6c on - windows. - -* Fortran DLL built with Intel 8.1 in .NET environment crushed the compiler, - To build Fortran Static library with Intel 8.1 in .NET environment - needs manually setting the project file, - please contact to hdfhelp@ncsa.uiuc.edu if you need to build - fortran static library with Intel 8.1 with .NET environment. - -* On at least one system, (SDSC DataStar), the scheduler (in this case - LoadLeveler) sends job status updates to standard error when you run - any executable that was compiled with the parallel compilers. - - This causes problems when running "make check" on parallel builds, as - many of the tool tests function by saving the output from test runs, - and comparing it to an exemplar. - - The best solution is to reconfigure the target system so it no longer - inserts the extra text. However, this may not be practical. - - In such cases, one solution is to "setenv HDF5_Make_Ignore yes" prior to - the configure and build. This will cause "make check" to continue after - detecting errors in the tool tests. However, in the case of SDSC DataStar, - it also leaves you with some 150 "failed" tests to examine by hand. - - A second solution is to write a script to run serial tests and filter - out the text added by the scheduler. A sample script used on SDSC - DataStar is given below, but you will probably have to customize it - for your installation. - - Observe that the basic idea is to insert the script as the first item - on the command line which executes the test. The script then - executes the test and filters out the offending text before passing - it on. - - #!/bin/csh - - set STDOUT_FILE=~/bin/serial_filter.stdout - set STDERR_FILE=~/bin/serial_filter.stderr - - rm -f $STDOUT_FILE $STDERR_FILE - - ($* > $STDOUT_FILE) >& $STDERR_FILE - - set RETURN_VALUE=$status - - cat $STDOUT_FILE - - tail +3 $STDERR_FILE - - exit $RETURN_VALUE - - You get the HDF make files and test scripts to execute your filter script - by setting the environment variable "RUNSERIAL" to the full path of the - script prior to running configure for parallel builds. Remember to - "unsetenv RUNSERIAL" before running configure for a serial build. - - Note that the RUNSERIAL environment variable exists so that we can - can prefix serial runs as necessary on the target system. On DataStar, - no prefix is necessary. However on an MPICH system, the prefix might - have to be set to something like "/usr/local/mpi/bin/mpirun -np 1" to - get the serial tests to run at all. - - In such cases, you will have to include the regular prefix in your - filter script. - - -%%%%1.6.3%%%% Release Information for hdf5-1.6.3 (22/September/04) - -HDF5 version 1.6.3 released on Wed Sep 22 11:30:11 CDT 2004 -================================================================================ - - -INTRODUCTION - -This document describes the differences between HDF5-1.6.2 and -HDF5-1.6.3, and contains information on the platforms tested and -known problems in HDF5-1.6.3. For more details check the HISTORY.txt -file in the HDF5 source. - -The HDF5 documentation can be found on the NCSA ftp server -(ftp.ncsa.uiuc.edu) in the directory: - - /HDF/HDF5/docs/ - -For more information look at the HDF5 home page at: - - http://hdf.ncsa.uiuc.edu/HDF5/ - -If you have any questions or comments, please send them to: - - hdfhelp@ncsa.uiuc.edu - -CONTENTS - -- New Features -- Support for new platforms and languages -- Bug Fixes since HDF5-1.6.2 -- Documentation -- Platforms Tested -- Supported Configuration Features Summary -- Known Problems - - -New Features -============ - - Configuration: - -------------- - - Added some initial support for making purify (or similar memory - checking products) happier by initializing buffers to zero and - disabling the internal free list code. To take advantage of this, - define 'H5_USING_PURIFY' in your CFLAGS when building the library. - QAK - 2004/07/23 - - - WINDOWS building,testing and installing improvements - - - On Windows, FORTRAN,C++ and C projects are merged into one zip file, - users can choose an option to build either FORTRAN or C++ or both - with basic C library.For detailed information, - please read INSTALL_Windows.txt. - - - On Windows, szip compression library with or without encoder can be easily - turned off or on when building HDF5. For detailed information, - please read INSTALL_Windows.txt, especially section V. - - - On Windows, an optional procedure for building,testing and installing - HDF5 from command line is provided. This procedure is supposed to be - convenient for experienced users, please read - INSTALL_windows_From_Command_Line.txt for details. - - - On Windows, an alternative short instruction document for building, - testing and installing HDF5 is provided. This instruction is supposed to - be convenient for general users, please read - INSTALL_Windows_Short.txt for details. - - - On Windows, h5repack,h5diff,h5ls and h5import tool tests have been added. - KY - 2004/9/16 - - - Library: - -------- - - Modified the way how HDF5 calculates 'pixels_per_scanline' parameter for - SZIP compression. Now there is no restriction on the size and shape of the - chunk except that the total number of elements in the chunk cannot be - bigger than 'pixels_per_block' parameter provided by the user. - EIP - 2004/07/21 - - HDF5 can now link to SZIP with or without szip's encoder. - The new API function H5Zget_filter_info can be used to check - szip's status. Attempting to assign szip to a dataset property - list or attempting to write with szip will generate an error if - szip's encoder is disabled. JL/NF - 2004/6/30 - - SZIP always uses K13 compression. This flag no longer needs to - be set when calling H5Pset_szip. If the flag for CHIP - compression is set, it will be ignored (since the two are mutually - exclusive). JL/NF - 2004/6/30 - - A new API function H5Fget_name was added. It returns the name - of the file by object(file, group, data set, named data type, - attribute) ID. SLU - 2004/06/29 - - A new API function H5Fget_filesize was added. It returns the - actual file size of the opened file. SLU - 2004/06/24 - - Added option that if $HDF5_DISABLE_VERSION_CHECK is set to 2, - will suppress all library version mismatch warning messages. - AKC - 2004/4/14 - - Parallel Library: - ----------------- - - Tools: - ------ - - h5repack was added to the tools suite. h5repack regenerates an HDF5 file - from another HDF5 file, optionally applying HDF5 filters (compression) - and/or chunking to the copied file. The filters options are read from - the command line. See /doc/html/Tools.html for more details. - PVN - 2004/9/13 - - - h5dump includes new features: - 1) Printing of dataset filters, storage layout and fill value information. - 2) Print a list of the file contents. - 3) Escape non printing characters. - 4) Print the content of the boot block. - 5) Print array indices with the data (the default). - These options are all switch controlled. See /doc/html/Tools.html for more details. - PVN - 2004/9/13 - - - F90 API: - -------- - - added new subroutines: - h5fget_filesize_f - h5iget_file_id_f - h5premove_filter_f - h5zget_filter_info_f - EIP 2004/9/21 - - - added new h5fget_name_f and h5fget_filesize_f subroutines - EIP 2004/07/08 - - C++ API: - -------- - - Added wrappers for array and variable length datatypes APIs - - Added wrappers for newly added APIs from H5T, H5F, and H5I - - Added many wrappers that were missing from the H5P API - - Added the ability to reference HDF5 objects to these classes: - DataSet, DataType, Group, and H5File (wrappers for H5R APIs) - BMR 2004/08/04 - - -Support for new platforms, languages and compilers. -======================================= - - Added PGI Fortran support for Linux64 (x86_64) systems - EIP - 2004/08/19 - - Absoft compiler f95 v9.0 is supported on Linux 2.4 32bit - EIP - 2004/07/29 - - HDF5 Fortran APIs are supported on Mac OSX with IBM XL Fortran - compiler version 8.1. This is a default compiler. - - HDF5 Fortran APIs are supported on MAC OSX with Absoft F95 compiler - version 8.2; set F9X environment variable to f95, for example - setenv F9X f95 - Use --disable-shared --enable-static configure flags when Absoft - compiler is used. - EIP - 2004/07/27 - -Bug Fixes since HDF5-1.6.2 release -================================== - - Library - ------- - - Fixed parallel bug in which some processes attempted collective - I/O while others did independent I/O. Bug appeared when some - processes used point selections, and others didn't. JRM - 2004/9/15 - - Corrected error where dataset region references were written in an - incorrect way on Cray machines. PVN & QAK - 2004/09/13 - - The H5Tget_native_type now determines the native type for integers - based on the precision. This is to avoid cases of wrongly converting - an int to a short in machines that have a short of 8 bytes but with - 32bit precision (e.g Cray SV1). PVN - 2004/09/07 - - Changed H5Dread() to not overwrite data in an application's buffer - with garbage when accessing a chunked dataset with an undefined fill - value and an unwritten chunk is uncountered. QAK - 2004/08/25 - - Fixed error which could cause a core dump when a type conversion - routine was registered after a compound datatype had been - converted and then an equivalent compound datatype was converted - again. QAK - 2004/08/07 - - Fixed memory overwrite when encoding "multi" file driver information - for file's superblock. QAK - 2004/08/05 - - Fixed obscure bug where a filter which failed during chunk allocation - could allow library to write uncompressed data to disk but think - the data was compressed. QAK - 2004/07/29 - - Fixed bug where I/O to an extendible chunked dataset with zero-sized - dimensions would cause library to fail an assertion. - QAK - 2004/07/27 - - Fixed bug where chunked datasets which have filters defined, - allocation time set to "late" and whose chunks don't align with - the dataspace bounds could have incorrect data stored when - overwriting the entire dataset on the first write. QAK - 2004/07/27 - - Added check to ensure that dataspaces have extents set. JML-2004/07/26 - - Fixed bug on some Solaris systems where HDF5 would try to use - gettimeofday() when that function didn't work properly. - JML - 2004/07/23 - - Fixed bug in H5Sset_extent_simple where setting maximum size to - non-zero, then to zero would cause an error. JML - 2004/07/20 - - Allow NULL pointer for buffer parameter to H5Dread & H5Dwrite - when not writing data ("none" selection or hyperslab or point - selection with no elements defined). QAK - 2004/07/20 - - Calling H5Gcreate() on "/" or "." throws an error instead of - failing quietly. JML - 2004/07/19 - - Fixed bug where setting file address size to be very small could - trigger an assert if the file grew to more than 64 KB. Now throws - an error and data can be recovered. JL/NF - 2004/07/14 - - Fixed bug where "resurrecting" a dataset was failing. - QAK - 2004/07/14 - - Fixed bug where incorrect data could be read from a chunked dataset - after it was extended. QAK - 2004/07/12 - - After compound datatype with variable-length string in the fields - is committed to file, the size is messed up when it's read back. - Fixed. SLU - 2004/06/11 - - Fixed potential file corruption bug when a block of metadata could - overlap the end of the internal metadata accumulator buffer and - the buffer would be extended correctly, but would incorrectly - change it's starting address. QAK - 2004/06/09 - - Opaque datatype with no tag failed for some operations. Fixed. - SLU - 2004/6/3 - - Fixed potential file corruption bug where dimensions that were - too large (a value greater than could be represented in 32-bits) - could cause the incorrect amount of space to be allocated in a - file for the raw data for the dataset. QAK - 2004/06/01 - - Fixed dtypes "sw long double -> double" failure in QSC class - machines. AKC - 2004/4/16 - - Configuration - ------------- - - Fixed the long compile time of H5detect.c when v7.x Intel Compiler - is used with optimization NOT off. AKC - 2004/05/20 - - Performance - ------------- - - Tools - ----- - - On SGI h5dump displayed only part of the data due to the bug - in the system printf; fixed. - EIP - 2004/09/21 - Documentation - ------------- - - Several descriptive errors have been fixed throughout the - documentation, particularly in the reference manual (RM). - A selection particularly worthy of note would be these: - - The H5Pset_szip description in the RM has been expanded and - corrected to facilitate use of SZIP compression. - - A note has been added to the H5Dcreate description that an - unexplained failure is likely to be due to a property list error - that is detected only at the time of dataset creation. - - - FMB - 2004/09/21 - - F90 API - ------- - - Fortran functions h5dwrite/read_f and h5awrite/read_f do not - accept dims parameter of INTEGER type anymore. Code was removed. - 2004/04/15 - C++ API - ------- - - H5::Exception's and its subclasses' constructors that were - overloaded to take char pointers are removed and constructors - that passed in reference of 'string' are changed to pass - by value. In addition, the default value of the data member - H5::Exception::detailMessage is changed from 0/NULL to - DEFAULT_MSG ("No detailed information provided".) - - Prototype for DSetCreatPropList::setLayout is changed: 1st parameter - is removed because it was there only by mistake. - BMR 2004/08/04 - -Documentation -============= - HDF5 Library documentation - -------------------------- - - HDF5 C++ API Reference Manual - This document has been added to the HDF5 document set. - The predecessor document, "HDF5 C++ Interfaces," has been removed. - - HDF5 C++ API Design Specification - A first draft of this document has been added to the HDF5 document - set.

We will provide - a fix. Please check ftp://ftp.ncsa.uiuc.edu/HDF/HDF5/current/src/patches/ - for the patches. - -* Fortran subroutine h5pget_driver_f doesn't return a correct driver information. - -* There are two h5dump xml tests(h5dump --xml thlink.h5 and h5dump --xml tmany.h5) - failed on windows xp with .NET for debug and debug dll. Release and Release - dll work fine. - -* The h5dump tests may fail to match the expected output on some platforms - (e.g. parallel jobs, Windows) where the error messages directed to - "stderr" do not appear in the "right order" with output from stdout. - This is not an error. - -* The stream-vfd test uses ip port 10007 for testing. If another - application is already using that port address, the test will hang - indefinitely and has to be terminated by the kill command. To try the - test again, change the port address in test/stream_test.c to one not - being used in the host. - -* The --enable-static-exec configure flag fails to compile for Solaris - platforms. This is due to the fact that not all of the system - libraries on Solaris are available in a static format. - - The --enable-static-exec configure flag also fails to correctly compile - on IBM SP2 platform for the serial mode. The parallel mode works fine - with this option. - - It is suggested that you don't use this option on these platforms - during configuration. - -* The Stream VFD was not tested yet under Windows. It is not supported - in the TFLOPS machine. - -* The ./dsets tests failed in the TFLOPS machine if the test program, - dsets.c, is compiled with the -O option. The hdf5 library still works - correctly with the -O option. The test program works fine if it is - compiled with -O1 or -O0. Only -O (same as -O2) causes the test - program to fail. - -* Certain platforms give false negatives when testing h5ls: - - Cray J90 and Cray T90IEEE give errors during testing when displaying - some floating-point values. These are benign differences due to - the different precision in the values displayed and h5ls appears to - be dumping floating-point numbers correctly. - -* Before building HDF5 F90 Library from source on Crays - replace H5Aff.f90, H5Dff.f90 and H5Pff.f90 files in the fortran/src - subdirectory in the top level directory with the Cray-specific files - from the site: - ftp://ftp.ncsa.uiuc.edu/HDF/HDF5/current/src/patches/ - -* On some platforms that use Intel and Absoft compilers to build HDF5 fortran library, - compilation may fail for fortranlib_test.f90, fflush1.f90 and fflush2.f90 - complaining about exit subroutine. Comment out the line - IF (total_error .ne. 0) CALL exit (total_error) - -* On IA32 and IA64 systems, if you use a compiler other than GCC (such as - Intel's ecc or icc compilers), you will need to modify the generated - "libtool" program after configuration is finished. On or around line 104 of - the libtool file, there are lines which look like: - - # How to pass a linker flag through the compiler. - wl="" - - change these lines to this: - - # How to pass a linker flag through the compiler. - wl="-Wl," - - UPDATE: This is now done automatically by the configure script. However, if - you still experience a problem, you may want to check this line in the - libtool file and make sure that it has the correct value. - -* Information about building with PGI and Intel compilers is available in - INSTALL file sections 5.7 and 5.8 - -* In LANL QSC, the new cc compiler has problems converting small values of - long long (absolute values less than 1**-308) to double. This triggers - the test/dtypes to report failure in the - Testing random sw long double -> double conversions - If -ieee is used, the converted doubles spread over the range 0.0 to 1**-308. - If -ieee is not used, the converted double values are mostly 0.0 but - occasionally as 1**-308. This has been reported to the system staff. - All other tests have passed. - -* On at least one system, (SDSC DataStar), the scheduler (in this case - LoadLeveler) sends job status updates to standard error when you run - any executable that was compiled with the parallel compilers. - - This causes problems when running "make check" on parallel builds, as - many of the tool tests function by saving the output from test runs, - and comparing it to an exemplar. - - The best solution is to reconfigure the target system so it no longer - inserts the extra text. However, this may not be practical. - - In such cases, one solution is to "setenv HDF5_Make_Ignore yes" prior to - the configure and build. This will cause "make check" to continue after - detecting errors in the tool tests. However, in the case of SDSC DataStar, - it also leaves you with some 150 "failed" tests to examine by hand. - - A second solution is to write a script to run serial tests and filter - out the text added by the scheduler. A sample script used on SDSC - DataStar is given below, but you will probably have to customize it - for your installation. - - Observe that the basic idea is to insert the script as the first item - on the command line which executes the test. The script then - executes the test and filters out the offending text before passing - it on. - - #!/bin/csh - - set STDOUT_FILE=~/bin/serial_filter.stdout - set STDERR_FILE=~/bin/serial_filter.stderr - - rm -f $STDOUT_FILE $STDERR_FILE - - ($* > $STDOUT_FILE) >& $STDERR_FILE - - set RETURN_VALUE=$status - - cat $STDOUT_FILE - - tail +3 $STDERR_FILE - - exit $RETURN_VALUE - - You get the HDF make files and test scripts to execute your filter script - by setting the environment variable "RUNSERIAL" to the full path of the - script prior to running configure for parallel builds. Remember to - "unsetenv RUNSERIAL" before running configure for a serial build. - - Note that the RUNSERIAL environment variable exists so that we can - can prefix serial runs as necessary on the target system. On DataStar, - no prefix is necessary. However on an MPICH system, the prefix might - have to be set to something like "/usr/local/mpi/bin/mpirun -np 1" to - get the serial tests to run at all. - - In such cases, you will have to include the regular prefix in your - filter script. - -%%%%1.6.2%%%% Release Information for hdf5-1.6.2 (12/February/04) - -HDF5 version 1.6.2 released on Thu Feb 12 14:18:13 CST 2004 -================================================================================ - - -INTRODUCTION - -This document describes the differences between HDF5-1.6.1 and -HDF5-1.6.2, and contains information on the platforms tested and -known problems in HDF5-1.6.2.

See the reference manual for a - full description of these new routines. QAK - 2003/12/11 - - Parallel Library: - ----------------- - - The parallel tests in testpar/ now provides different levels of - verbosity via the '-v' option. The default is less verbose - than before. AKC - 2004/01/23 - - Added parallel test, test_mpio_1wMr, which tests if the - underlaying parallel I/O system is conforming to the POSIX - write/read requirement. This version includes options of using - atomicity and file-sync. AKC - 2003/11/27 - - Tools: - ------ - - Added option -showconfig to compiler tools (h5cc,h5fc,h5c++). - AKC - 2004/01/08 - - Install the "h5cc" and "h5fc" tools as "h5pcc" and "h5pfc" - respectively if library is built in parallel mode.

QAK - 2004/01/31 - - Fixed several errors in B-tree deletion code which could cause a - B-tree (used with groups and chunked datasets) to become corrupt - with the right sequence of deleted objects. QAK - 2004/01/19 - - Fixed small internal memory leaks of fill-value information. - QAK - 2004/01/13 - - Fixed bug that caused variable-length datatypes (strings or sequences) - used for datasets in files with objects that were unlinked to - fail to be read/written to a file. QAK - 2004/01/13 - - Detect situation where szip 'pixels per block' is larger than the - fastest changing dimension of a dataset's chunk size and disallow - this (due to limits in szip library). QAK - 2003/12/31 - - Fixed bug with flattened hyperslab selections that would generate - incorrect hyperslab information with certain high-dimensionality - combinations of start/stride/count/block information. - QAK - 2003/12/31 - - Fixed bug with variable-length datatypes used in compound datatypes. - SLU - 2003/12/29 - - Fixed bug in parallel I/O routines that would cause reads from - "short datasets" (datasets which were only partially written out) - to return invalid data. QAK & AKC - 2003/12/19 - - Fixed bug where scalar dataspaces for attributes were reporting as - simple dataspaces. QAK - 2003/12/13 - - Fixed problem with selection offsets of hyperslab selections in - chunked datasets causing the library to go into an infinite loop. - QAK - 2003/12/13 - - Fixed H5Giterate to avoid re-using index parameter after iteration - callback has been called (allows iteration callback to modify the - index parameter itself). QAK - 2003/12/06 - - Fixed various floating-point conversion problems, including a - change which could corrupt data when converting from double->float. - QAK - 2003/11/24 - - Changed "single process" metadata writing in library to collective - I/O by all processes, in order to guarantee correct data being - written with MPI-I/O. QAK - 2003/11/20 - - Fixed problems with fill values and variable-length types and also - I/O on VL values that were set to NULL. QAK - 2003/11/08 - - Fixed problems with MPI datatypes that caused ASCI Q machine to - hang. QAK - 2003/10/28 - - Removed HDF5_MPI_PREFER_DERIVED_TYPES environment variable support, - since it had no benefit. QAK - 2003/10/28 - - Single hyperslab selections (which were set with only one call to - H5Sselect_hyperslab) that had dimensions that could be "flattened" - but were interspersed with dimensions that could not be flattened - were not correctly handled, causing core dumps. QAK - 2003/10/25 - - Avoid metadata cache from preempting current dataset object header - when looking up information about the named datatype that the - dataset uses. QAK - 2003/10/20 - - Configuration - ------------- - - Parallel I/O with the MPI-I/O driver will no longer work if the - filesystem is not POSIX compliant. The "HDF5_MPI_1_METAWRITE" - environment variable has been removed. QAK - 2004/01/30 - - Performance - ------------- - - More optimizations to inner loops of datatype conversions for - integers and floats which give a 10-50% speedup.

Release and Release - dll work fine. - -* The h5dump tests may fail to match the expected output on some platforms - (e.g. parallel jobs, Windows) where the error messages directed to - "stderr" do not appear in the "right order" with output from stdout. - This is not an error. - -* The stream-vfd test uses ip port 10007 for testing. If another - application is already using that port address, the test will hang - indefinitely and has to be terminated by the kill command. To try the - test again, change the port address in test/stream_test.c to one not - being used in the host. - -* The --enable-static-exec configure flag fails to compile for Solaris - platforms. This is due to the fact that not all of the system - libraries on Solaris are available in a static format. - - The --enable-static-exec configure flag also fails to correctly compile - on IBM SP2 platform for the serial mode. The parallel mode works fine - with this option. - - It is suggested that you don't use this option on these platforms - during configuration. - -* The Stream VFD was not tested yet under Windows. It is not supported - in the TFLOPS machine. - - -* The ./dsets tests failed in the TFLOPS machine if the test program, - dsets.c, is compiled with the -O option. The hdf5 library still works - correctly with the -O option. The test program works fine if it is - compiled with -O1 or -O0. Only -O (same as -O2) causes the test - program to fail. - -* Certain platforms give false negatives when testing h5ls: - - Cray J90 and Cray T90IEEE give errors during testing when displaying - some floating-point values. These are benign differences due to - the different precision in the values displayed and h5ls appears to - be dumping floating-point numbers correctly. - -* Before building HDF5 F90 Library from source on Crays - replace H5Aff.f90, H5Dff.f90 and H5Pff.f90 files in the fortran/src - subdirectory in the top level directory with the Cray-specific files - from the site: - ftp://hdf.ncsa.uiuc.edu/pub/outgoing/hdf5/hdf5-1.6.2/F90_source_for_Crays - -* On some platforms that use Intel compilers to build HDF5 fortran library, - compilation may fail for fortranlib_test.f90, fflush1.f90 and fflush2.f90 - complaining about exit subroutine. Comment out the line - IF (total_error .ne. 0) CALL exit (total_error) - -* On IA32 and IA64 systems, if you use a compiler other than GCC (such as - Intel's ecc or icc compilers), you will need to modify the generated - "libtool" program after configuration is finished. On or around line 104 of - the libtool file, there are lines which look like: - - # How to pass a linker flag through the compiler. - wl="" - - change these lines to this: - - # How to pass a linker flag through the compiler. - wl="-Wl," - - UPDATE: This is now done automatically by the configure script. However, if - you still experience a problem, you may want to check this line in the - libtool file and make sure that it has the correct value. - -* Information about building with PGI and Intel compilers is available in - INSTALL file sections 5.7 and 5.8 - -* In LANL QSC, the new cc compiler has problems converting small values of - long long (absolute values less than 1**-308) to double. This triggers - the test/dtypes to report failure in the - Testing random sw long double -> double conversions - If -ieee is used, the converted doubles spread over the range 0.0 to 1**-308. - If -ieee is not used, the converted double values are mostly 0.0 but - occassionaly as 1**-308. This has been reported to the system staff. - All other tests have passed. - -* On AIX 5.1 when 64-bit parallel C Library is built with zlib configured in, - compilation fails for H5Zdeflate.c. To bypass the problem, remove "const" - definition in front of H5Z_DEFLATE in H5Zpkg.h line 29. - -%%%%1.6.1%%%% Release Information for hdf5-1.6.1 (16/October/03) - -15.

(Apr 26, 2002) - BMR - 2003/10/10 - - Added new member function H5::DataSet::fillMemBuf per the new C - API H5Dfill, which fills the elements in a selection for a memory - buffer with a fill value. (May 16, 2002) BMR - 2003/10/10 - - Added the new member function getMemberIndex to H5::EnumType - and H5::CompType to match the new C API H5Tget_member_index. Given - the name of a member of an enumeration or compound datatype, this - new function queries the index of the member. (May 16, 2002) - BMR - 2003/10/10 - - Added these member functions to H5::Group per the new C functions - H5Gget_num_objs, H5Gget_objname_by_idx and H5Gget_objtype_by_idx: - + getNumObjs: Returns the number of objects in the group. - + getObjnameByIdx: Retrieves the name of an object in a group, - given an index - + getObjTypeByIdx: Returns the type of an object in a group, - given an index - (Jan 20, 2003) BMR - 2003/10/10 - - -Support for new platforms, languages and compilers. -======================================= - - gcc 3.3.1 is supported on Linux. - - -Bug Fixes since HDF5-1.6.0 release -================================== - - Library - ------- - - Fixed incorrect datatype of the third parameter to the Fortran90 - h5pset(get)_cache_f functions (INTEGER to INTEGER(SIZE_T)) EIP - 2003/10/13 - - Fixed problems with accessing variable-length data datatypes on - Crays.

QAK - 2003/09/16 - - Allow compound datatypes to grow in size. SLU - 2003/09/10 - - Detect if a type is already packed before attempting to pack it - again or check if it is locked. SLU - 2003/09/10 - - Corrected bug when opening a file twice with read-only permission - for one open and then closing the read-only access file ID would - generate an error. QAK - 2003/09/10 - - Corrected bug in repeated calls to H5Pget_access_plist() which would - incorrectly manage reference counts of internal information and - eventually blow up. QAK - 2003/09/02 - - Return rank of the array datatype on successful call to - H5Tget_array_dims(). QAK - 2003/08/30 - - Corrected bug in H5Tdetect_class which was not correctly detecting - datatype classes of fields in nested compound datatypes in some - circumstances.

Release and Release - dll work fine. - -* The h5dump tests may fail to match the expected output on some platforms - (e.g. parallel jobs, Windows) where the error messages directed to - "stderr" do not appear in the "right order" with output from stdout. - This is not an error. - -* The stream-vfd test uses ip port 10007 for testing. If another - application is already using that port address, the test will hang - indefinitely and has to be terminated by the kill command. To try the - test again, change the port address in test/stream_test.c to one not - being used in the host. - -* The --enable-static-exec configure flag fails to compile for Solaris - platforms. This is due to the fact that not all of the system - libraries on Solaris are available in a static format. - - The --enable-static-exec configure flag also fails to correctly compile - on IBM SP2 platform for the serial mode. The parallel mode works fine - with this option. - - It is suggested that you don't use this option on these platforms - during configuration. - -* With the gcc 2.95.2 compiler, HDF 5 uses the `-ansi' flag during - compilation. The ANSI version of the compiler complains about not being - able to handle the `long long' datatype with the warning: - - warning: ANSI C does not support `long long' - - This warning is innocuous and can be safely ignored. - - -* The Stream VFD was not tested yet under Windows. It is not supported - in the TFLOPS machine. - - -* The ./dsets tests failed in the TFLOPS machine if the test program, - dsets.c, is compiled with the -O option. The hdf5 library still works - correctly with the -O option. The test program works fine if it is - compiled with -O1 or -O0. Only -O (same as -O2) causes the test - program to fail. - -* Certain platforms give false negatives when testing h5ls: - - Cray J90 and Cray T90IEEE give errors during testing when displaying - some floating-point values. These are benign differences due to - the different precision in the values displayed and h5ls appears to - be dumping floating-point numbers correctly. - -* Before building HDF5 F90 Library from source on Crays - replace H5Aff.f90, H5Dff.f90 and H5Pff.f90 files in the fortran/src - subdirectory in the top level directory with the Cray-specific files - from the site: - -* On some platforms that use Intel compilers to build HDF5 fortran library, - compilation may fail for fortranlib_test.f90, fflush1.f90 and fflush2.f90 - complaining about exit subroutine. Comment out the line - IF (total_error .ne. 0) CALL exit (total_error) - - ftp://hdf.ncsa.uiuc.edu/pub/outgoing/hdf5/hdf5-1.6.0/F90_source_for_Crays - -* On IA32 and IA64 systems, if you use a compiler other than GCC (such as - Intel's ecc or icc compilers), you will need to modify the generated - "libtool" program after configuration is finished. On or around line 104 of - the libtool file, there are lines which look like: - - # How to pass a linker flag through the compiler. - wl="" - - change these lines to this: - - # How to pass a linker flag through the compiler. - wl="-Wl," - - UPDATE: This is now done automatically by the configure script. However, if - you still experience a problem, you may want to check this line in the - libtool file and make sure that it has the correct value. - -* Information about building with PGI and Intel compilers is available in - INSTALL file sections 5.7 and 5.8 -%%%%1.6.0%%%% Release Information for hdf5-1.6.0 (03/July/03) - -14. Release information for HDF5 version 1.6.0 -================================================ - - -INTRODUCTION - -This document describes the differences between HDF5-1.4.* and -HDF5-1.6.0, and contains information on the platforms tested and -known problems in HDF5-1.6.0. For more details check the HISTORY.txt -file in the HDF5 source. - -The HDF5 documentation can be found on the NCSA ftp server -(ftp.ncsa.uiuc.edu) in the directory: - - /HDF/HDF5/docs/ - -For more information look at the HDF5 home page at: - - http://hdf.ncsa.uiuc.edu/HDF5/ - -If you have any questions or comments, please send them to: - - hdfhelp@ncsa.uiuc.edu - -CONTENTS - -- New Features -- Support for new platforms and languages -- Bug Fixes since HDF5-1.4.0 -- Platforms Tested -- Known Problems - - -New Features -============ - -Configuration: --------------- -The following flags have been added to the configuration script: ---enable-hdf5v1_4 Compile the HDF5 v1.4 compatibility interface ---enable-filters=all Turn on all internal I/O filters. One may also - specify a comma-separated list of filters or the - word no. The default is all internal I/O filters. ---with-mpe=DIR Use MPE instrumentation [default=no] ---with-szlib=DIR Use szlib library for external szlib I/O filter - [default=no] - -Library: --------- - Summary: This release has the following new features that are not - available in 1.4.* releases - - 1. Generic properties to give application more control on I/O pipeline - 2. Time allocation and fill value properties - 3. New filters: external compression filter szip - internal shuffling and checksum filters - 4. Compact storage layout for datasets - 5. Redesigned I/O pipeline for better performance. - - For more information see - http://hdf.ncsa.uiuc.edu/HDF5/doc_resource/SZIP/index.html - http://hdf.ncsa.uiuc.edu/HDF5/doc/ADGuide.html - http://hdf.ncsa.uiuc.edu/HDF5/doc/ADGuide/Changes.html - - Complete list of changes: - - * Changed dataset modification time to _not_ be updated when raw data is - written to a dataset. The modification time is only updated when the - dataset's metadata is modified. QAK - 2003/06/10 - * Changed H5Sget_select_bounds to use 'hssize_t *' for start and end - parameters, instead of 'hsize_t *', to better match other parts of the - dataspace API. QAK - 2003/06/04 - * Changed raw data I/O to only access each chunk once, improving performance - in many situations with hyperslabs and large chunks or chunks with - filters. These improvements are currently limited to serial I/O, with - similar parallel I/O improvements forthcoming sometime in the future. - QAK - 2003/05/07 - * Added parameter to the MPI/POSIX driver. If GPFS is enabled (by - modifying the H5FDmpiposix.c file to uncomment the USE_GPFS_HINTS - macro), then this extra parameter will turn GPFS hints on and off - during runtime. BW - 2003/05/05 - * Added option to print 1-byte integer datasets as ASCII to h5dump. BW - - 2003/04/30 - * Added a new utility "h5fc". It can be used to compile easily Fortran - programs which use HDF5. It automatically uses the compiler the HDF5 - library was built with and links in any libraries HDF5 requires. - BW - 2003/04/10 - * Added new dataset creation property list functions for working with - I/O filters: H5Pmodify_filter, H5Pget_filter_by_id and - H5Pall_filters_avail. Also changed H5Zregister to use new method - of registering filters with library. QAK - 2003/04/08 - * The first version of szip compression support were implemented. - User should have static szlib library installed. Using function - H5Pset_szip to pass the szip parameters to the HDF5 library. - More detailed decription of the process will be followed. - KY-2003/04/01 - * Added Fletcher32 checksum as a filter in pipeline. It only works in - chunked dataset. SLU - 2003/2/11 - * MPICH/MPE instrumentation feature added. Use --with-mpe[=DIR] to configure - it. AKC - 2003/1/3 - * New functions H5Gget_num_objs, H5Gget_objname_by_idx and H5Gget_objtype_by_idx - are added to the library. SLU - 2002/11/25 - * H5Dget_offset is added to return the offset of a dataset's data relative - to the beginning of the file. SLU - 2002/11/7 - * Functions H5Tget_native_type and H5Tis_variable_str are added. The first - one reconstructs a datatype based on native memory datatype. The second - one checks if a datatype is variable string. SLU - 2002/11/6 - * Added environment variable "HDF5_DISABLE_VERSION_CHECK", which disables - the version checking between the header files and the library linked into - an application if set to '1'. This should be used with caution, mis- - matched headers and library binaries can cause _serious_ problems. - QAK - 2002/10/15 - * Added new API function to get the name of an object in a file, using - an open ID (hid_t). QAK - 2002/10/14 - * Added API functions to return pointer to low-level file handle - (H5Fget_vfd_handle and H5FDget_vfd_handle) and related property list - setting functions(H5Pset_family_offset and H5Pset_multi_type). - SLU - 2002/09/30 - * Changed "H5P[set|get]_space_time" functions to "H5P[set|get]_alloc_time" - Unify all symbolic names for these functions to use "alloc time" instead - of other names. QAK - 2002/09/13 - * Added "H5D_SPACE_ALLOC_INCR" setting to H5D_SPACE_ALLOC_EARLY and - H5D_SPACE_ALLOC_LATE for H5Dset_space_time(). This allows chunked - datasets to be incrementally allocated as in the 1.4.x branch. - QAK - 2002/08/27 - * Compact dataset is added to the library. The data will be stored in - the header message of dataset layout. Space allocation time has to be - EARLY. No hyperslab is supported for parallel collective write. There - is no API changes except activating H5Pset_layout and H5Pget_layout for - compact dataset. -SLU, 2002/8/20 - * Added 'closing' parameter to VFL 'flush' callback function and H5FDflush. - This allows the library to indicate that the file will be closed - immediately following the call to 'flush' and can be used to avoid actions - that are duplicated in the VFL 'close' callback function. QAK - 2002/05/20 - * Added feature to parallel chunk allocation routine to not write fill - values to chunks allocated if the user has set the "fill time" to never. - This can improve parallel I/O performance for chunked - datasets. QAK - 2002/05/17 - * New functions H5Glink2 and H5Gmove2 were added to allow link and move to - be in different locations in the same file. The old functions H5Glink - and H5Gmove remain valid. SLU - 2002/04/26 - * Fill-value's behaviors for contiguous dataset have been redefined. - Basicly, dataset won't allocate space until it's necessary. Full details - are available at http://hdf.ncsa.uiuc.edu/RFC/Fill_Value, at this moment. - SLU - 2002/04/11 - * Added new routine "H5Dfill" to fill a selection with a particular value - in memory. QAK - 2002/04/09 - * Improved performance of "regular" hyperslab I/O when using MPI-IO and the - datatype conversion is unneccessary. QAK - 2002/04/02 - * Improved performance of single hyperslab I/O when datatype conversion is - unneccessary. QAK - 2002/04/02 - * Added new "H5Sget_select_type" API function to determine which type of - selection is defined for a dataspace ("all", "none", "hyperslab" or - "point"). QAK - 2002/02/07 - * Added support to read/write portions of chunks directly, if they are - uncompressed and too large to cache. This should speed up I/O on chunked - datasets for a few more cases. QAK - 2002/01/31 - * Added H5Rget_obj_type() API function, which performs the same functionality - as H5Rget_object_type(), but requires the reference type as a parameter - in order to correctly handle dataset region references. Moved - H5Rget_object_type() to be only compiled into the library when v1.4 - compatibility is enabled. - * Added a new file access property, file close degree, to control file - close behavior. It has four values, H5F_CLOSE_WEAK, H5F_CLOSE_SEMI, - H5F_CLOSE_STRONG, and H5F_CLOSE_DEFAULT. Two correspont functions - H5Pset_fclose_degree and H5Pget_fclose_degree are also provided. Two - new functions H5Fget_obj_count and H5Fget_obj_ids are offerted to assist - this new feature. For full details, please refer to the reference - manual under the description of H5Fcreate, H5Fopen, H5Fclose and the - functions mentioned above. - * Removed H5P(get|set)_hyper_cache API function, since the property is no - longer used. - * Improved performance of non-contiguous hyperslabs (built up with - several hyperslab selection calls). - * Improved performance of single, contiguous hyperslabs when reading or - writing. - * As part of the transition to using generic properties everywhere, the - parameter of H5Pcreate changed from H5P_class_t to hid_t, as well - the return type of H5Pget_class changed from H5P_class_t to hid_t. - Further changes are still necessary and will be documented here as they - are made. - * Improved regular hyperslab I/O by about a factor of 6 or so. - * Modified the Pablo build procedure to permit building of the instrumented - library to link either with the Trace libraries as before or with the - Pablo Performance Caputure Facility. - * Added new F90 APIs for generic properties, new filters, and - time/space allocation properties. - * C++ API: - - Added two new member functions: Exception::getFuncName() and - Exception::getCFuncName() to provide the name of the member - function, where an exception is thrown. - - IdComponent::operator= becomes a virtual function because - DataType, DataSpace, and PropList provide their own - implementation. The new operator= functions invoke H5Tcopy, - H5Scopy, and H5Pcopy to make a copy of a datatype, dataspace, - and property list, respectively. - -Parallel Library: ------------------ - -Tools: ------- - * When the "-S" option for "simple" output is chosen, h5ls now displays - modification times of datasets in UTC instead of local time. - QAK - 2003/06/06 - * h5diff to compare two HDF5 files was added - * h5import to import ascii and binary data to an HDF5 file was added. - Old h5import tool in the tools/misc directory was renamed to - h5createU8 to reflect its purpose. h5createU8 will be deleted in - 1.6.1 release. - * Two new scripts h5fc and h5c++ were added to compile F90 and C++ - HDF5 applications. - -Support for new platforms, languages and compilers. -======================================= - * Added C++ API support on HPUX11.00. BMR - 2003/03/19 - * Absoft compiler is supported for Fortran HDF5 Library. - When building with Absoft compiler, add -DH5_ABSOFT to - C compilation flags to get correct names of C functions - called by Fortran APIs. - - -Bug Fixes since HDF5-1.4.0 release -================================== - -Library -------- - * Don't attempt to perform collective I/O on chunked datasets with - parallel I/O. QAK - 2003/06/05 - * The library now correctly reuses space when objects are deleted in the - file. This should be handled correctly for every situation, except - datasets with variable-length datatypes are not returning the space they - use in the global heap currently. QAK - 2003/04/13 - * Fixed error in B-tree deletion routine which could cause groups to be - corrupted when objects are removed from them. - QAK - 2003/04/11 - * Fixed error in file space freeing code which could cause metadata to - fail to be written to the file. - QAK - 2003/04/11 - * -O caused errors in AIX 5.x platforms. Removed it from - --enable-production mode. AKC - 2003/03/31 - * Corrected memory/resource leaks in per-thread key information when - thread-safe operation was enabled. QAK - 2003/02/07 - * Improved error assertion for nil VL strings, making it fails with error - stack instead of just assertion failure. SLU - 2002/12/16 - * Added two new API functions: H5Zunregister & H5Zfilter_avail. - QAK - 2002/11/16 - * Add data shuffle filter(source code H5Zshuffle.c), the combination of the - shuffling and compression can make data compression better without suffering - much encoding and decoding CPU time for many application datasets(especially - for floating point data). This adds a new API function: H5Pset_shuffle. - KY - 2002/11/13 - * Allow scalar dataspaces to be used for parallel I/O. QAK - 2002/11/05 - * New functions H5Gget_comment(modification), H5Aget_storage_size, - H5Arename. SLU - 2002/10/29 - * Fixed an assertion of H5S_select_iterate that did not account for scalar - type that has no dimension sizes. AKC - 2002/10/15 - * Partially fixed space allocation inefficiencies in the file by - improving our algorithms for re-using freed space. QAK - 2002/08/27 - * Fixed data corruption problem which could occur when fill values were - written to a contiguously stored dataset in parallel. QAK - 2002/08/27 - * Fixed VL memory leak when data is overwritten. The heap objects holding - old data are freed. If the fill value writting time is set to - H5D_FILL_TIME_NEVER, the library prohibits user to create VL type dataset. - The library free all the heap objects storing VL type if there is nested - VL type(a VL type contains another VL type). SLU - 2002/07/10 - * Tweaked a few API functions to use 'size_t' instead of 'unsigned' or - 'hsize_t', which may cause errors in some cases. - - -Configuration -------------- - * Included the both the examples of fortran and c++ "make check-install" - testing. This tests the correctness of the h5fc command. AKC - 2003/04/22 - * When using gcc 3.x, we use -std=c99 instead of -ansi for compiling. - QAK - 2003/04/11 - * IA64 platform has its own configure setting and use Intel Compilers as - the default compilers (were gcc and pgf90 before.)

If another - application is already using that port address, the test will hang - indefinitely and has to be terminated by the kill command. To try the - test again, change the port address in test/stream_test.c to one not - being used in the host. - -* The --enable-static-exec configure flag fails to compile for Solaris - platforms. This is due to the fact that not all of the system - libraries on Solaris are available in a static format. - - The --enable-static-exec configure flag also fails to correctly compile - on IBM SP2 platform for the serial mode. The parallel mode works fine - with this option. - - It is suggested that you don't use this option on these platforms - during configuration. - -* With the gcc 2.95.2 compiler, HDF 5 uses the `-ansi' flag during - compilation. The ANSI version of the compiler complains about not being - able to handle the `long long' datatype with the warning: - - warning: ANSI C does not support `long long' - - This warning is innocuous and can be safely ignored. - - -* The Stream VFD was not tested yet under Windows. It is not supported - in the TFLOPS machine. - - -* The ./dsets tests failed in the TFLOPS machine if the test program, - dsets.c, is compiled with the -O option. The hdf5 library still works - correctly with the -O option. The test program works fine if it is - compiled with -O1 or -O0. Only -O (same as -O2) causes the test - program to fail. - -* Certain platforms give false negatives when testing h5ls: - - Cray J90 and Cray T90IEEE give errors during testing when displaying - some floating-point values. These are benign differences due to - the different precision in the values displayed and h5ls appears to - be dumping floating-point numbers correctly. - -* Before building HDF5 F90 Library from source on Crays - replace H5Aff.f90, H5Dff.f90 and H5Pff.f90 files in the fortran/src - subdirectory in the top level directory with the Cray-specific files - from the site: - -* On some platforms that use Intel compilers to build HDF5 fortran library, - compilation may fail for fortranlib_test.f90, fflush1.f90 and fflush2.f90 - complaining about exit subroutine. Comment out the line - IF (total_error .ne. 0) CALL exit (total_error) - - ftp://hdf.ncsa.uiuc.edu/pub/outgoing/hdf5/hdf5-1.6.0/F90_source_for_Crays - -* On IA32 and IA64 systems, if you use a compiler other than GCC (such as - Intel's ecc or icc compilers), you will need to modify the generated - "libtool" program after configuration is finished. On or around line 104 of - the libtool file, there are lines which look like: - - # How to pass a linker flag through the compiler. - wl="" - - change these lines to this: - - # How to pass a linker flag through the compiler. - wl="-Wl," - - UPDATE: This is now done automatically by the configure script. However, if - you still experience a problem, you may want to check this line in the - libtool file and make sure that it has the correct value. - -* Information about building with PGI and Intel compilers is available in - INSTALL file sections 5.7 and 5.8 ------------------------------------------------------------------------ -%%%%1.4.5%%%% Release Information for hdf5-1.4.5 (02/February/03) - - -13. Release information for HDF5 version 1.4.5 -============================================================================== - - -INTRODUCTION - -This document describes the differences between HDF5-1.4.4 and -HDF5-1.4.5, and contains information on the platforms tested and -known problems in HDF5-1.4.5. For additional information check the -HISTORY.txt file in the HDF5 source. - -The HDF5 documentation can be found on the NCSA ftp server -(ftp.ncsa.uiuc.edu) in the directory: - - /HDF/HDF5/docs/ - -For more information, see the HDF5 home page at: - - http://hdf.ncsa.uiuc.edu/HDF5/ - -If you have any questions or comments, please send them to: - - hdfhelp@ncsa.uiuc.edu - - -CONTENTS - -- New Features -- Bug Fixes since HDF5-1.4.4 -- Performance Improvements -- Documentation -- Platforms Tested -- Supported Configuration Features -- Known Problems - - -New Features -============ - o Configuration - ================ - * Added "unofficial support" for building with a C++ compiler (or at least - not failing badly when building with a C++ compiler). QAK - 2003/01/09 - * Added "unofficial support" for AIX 64bits. See INSTALL for configure - details. AKC - 2002/08/29 - * Added "--with-dmalloc" flag, to easily enable support for the 'dmalloc' - debugging malloc implementation. QAK - 2002/07/15 - - o Library - ========= - o General - --------- - * Allow scalar dataspaces to be used for parallel I/O. QAK - 2002/11/05 - * Added environment variable "HDF5_DISABLE_VERSION_CHECK", which disables - the version checking between the header files and the library linked - into an application if set to '1'. This should be used with caution, - mis-matched headers and library binaries can cause _serious_ problems. - QAK - 2002/10/15 - * Partially fixed space allocation inefficiencies in the file by - improving our algorithms for re-using freed space. QAK - 2002/08/27 - * API tracing has been improved. Nested API calls don't screw up the - output format; function call and return event times can be logged; - total time spent in each function can be logged. The following - HDF5_DEBUG environment variable words affect tracing: - trace -- turn on/off basic tracing - ttimes -- turn on tracing and report event times and - time spent in each API function. - ttop -- turn on tracing but display only top-level - API calls. - - o APIs - ------ - * Several missing fortran APIs have been added to the library: - - h5get_libversion_f h5tget_member_index_f h5dget_storage_size_f - h5check_version_f h5tvlen_create_f h5dvlen_get_max_len_f - h5garbage_collect_f h5dwrite_vl_f - h5dont_atexit_f h5dread_vl_f - - Functions h5dvlen_get_max_len_f, h5dwrite_vl_f, and h5dread_vl_f support - VL Length C APIs functionality for integer, real and string datatypes. - See HDF5 Reference Manual and HDF5 FORTRAN90 User's Notes for more - information and for the functions description. - - o Parallel library - ================== - * The MPI-posix virtual file driver makes gpfs_fcntl() hints to tell - the underlying GPFS file system to avoid prefetching byte range - tokens if USE_GPFS_HINTS is defined when this file is compiled. - This temporary solution is intended to be removed once the HDF5 - API supports the necessary functionality that makes it possible - for this sort of thing do be done at a higher software layer. - RPM - 2002/12/03 - * Added MPI-posix VFL driver. This VFL driver uses MPI functions to - coordinate actions, but performs I/O directly with POSIX sec(2) - (i.e. open/close/read/write/etc.) calls. This driver should _NOT_ - be used to access files that are not on a parallel filesystem. - The following API functions were added: - herr_t H5Pset_fapl_mpiposix(hid_t fapl_id, MPI_Comm comm); - herr_t H5Pget_fapl_mpiposix(hid_t fapl_id, MPI_Comm *comm/*out*/); - QAK - 2002/07/15 - - - - o Support for new platforms and languages - ========================================= - * C++ API now works on the Origin2000 (IRIX6.5.14.) BMR - 2002/11/14 - - - o Misc. - ========================================= - HDF5 1.4.5 works with Portland Group Compilers (pgcc, pgf90 and pgCC - version 4.0-2) on Linux 2.4 - - -Bug Fixes since HDF5-1.4.4 Release -================================== - * H5Fopen without the H5F_ACC_CREAT flag should not succeed in creating - a new file with the 'core' VFL driver. QAK - 2003/01/24 - * Corrected metadata caching bug in parallel I/O which could cause hangs - when chunked datasets were accessed with independent transfer mode. - QAK - 2003/01/23 - * Allow opening objects with unknown object header messages. - QAK - 2003/01/21 - * Added improved error assertion for nil VL strings. It return error - stack instead of a simple assertion. SLU - 2002/12/16 - * Fixed h5dump bug(cannot dump data and datatype) for VL string. - SLU - 2002/11/18 - * Fixed error condition where "none" selections were not being handled - correctly in serial & parallel. QAK - 2002/10/29 - * Fixed problem where optimized hyperslab routines were incorrectly - invoked for parallel I/O operations in collective mode. QAK - 2002/07/22 - * Fixed metadata corruption problem which could occur when many objects - are created in a file during parallel I/O. QAK - 2002/07/19 - * Fixed minor problem with configuration when users specified /usr/include - and /usr/lib for the --with-* options that some compilers can't - handle.

Comment the call to EXEC subroutine - in each program, or get a patch for the HDF5 Fortran source code. - - * Fortran external dataset test fails on Linux 2.4 with pgf90 compiler. - - * On Windows, h5dump may abort printing if a VL string is longer than 4096 - bytes due to a compiler problem. It'll be fixed in v1.6 release. - - * Datasets or attributes which have a variable-length string datatype are - not printing correctly with h5dump and h5ls. - - * When a dataset with the variable-length datatype is overwritten, - the library can develop memory leaks that cause the file to become - unnecessarily large. This is planned to be fixed in the next release. - - * On the SV1, the h5ls test fails due to a difference between the - SV1 printf precision and the printf precision on other platforms. - - * The h5dump tests may fail to match the expected output on some - platforms (e.g. SP2 parallel, Windows) where the error messages - directed to "stderr" do not appear in the "right order" with output - from stdout. This is not an error. - - * The --enable-static-exec configure flag fails to compile for HP-UX - 11.00 platforms. - - * The executables are always dynamic on IRIX64 6.5(64 and n32) and - IRIX 6.5 even if they are configured with --enable-static-exec. - - * IRIX 6.5 fails to compile if configured with --enable-static-exec. - - * The executables are always dynamic on Solaris 2.7 ans 2.8(64 and n32) - even if they are configured with --enable-static-exec. - - * The HDF5_MPI_OPT_TYPES optimization code in the parallel HDF5 will cause - a hang in some cases when chunked storage is used. This is now set to - be off by default. One may turn it on by setting the environment - variable HDF5_MPI_OPT_TYPES to a non-zero value such as 1. - - * On OSF1 v5.1 and IA32 h5dumpgentst program that generates test files - for h5dump, gives segmentation fault. - - * On Windows platforms, C and Fortran tests fail with the debug DLL version - of the Library if built from all_withf90.zip file. - - * On Cray T3E (sn6606 2.0.6.08 unicosmk CRAY T3E) with Cray Standard C Version 6.6.0.1.3 - compiler optimization causes errors in many HDF5 Library tests. Use -g -h zero flags - to build HDF5 Library. - - * On Cray SV1 10.0.1. 0 datatype convertion test fails. Please check HDF FTP site - if patch is available.

For more details check the HISTORY.txt -file in the HDF5 source. - -The HDF5 documentation can be found on the NCSA ftp server -(ftp.ncsa.uiuc.edu) in the directory: - - /HDF/HDF5/docs/ - -For more information, see the HDF5 home page at: - - http://hdf.ncsa.uiuc.edu/HDF5/ - -If you have any questions or comments, please send them to: - - hdfhelp@ncsa.uiuc.edu - - -CONTENTS - -- New Features -- Bug Fixes since HDF5-1.4.3 -- Performance Improvements -- Documentation -- Platforms Tested -- Supported Configuration Features -- Known Problems - - -New Features -============ - o Configuration - ================ - * The H4 to H5 tools have been removed from the main source and placed - in a separate package. You can get these tools from the HDF ftp site - (ftp://hdf.ncsa.uiuc.edu/). The "--with-hdf4" command-line option - during configure is no longer valid. BW - 2002/06/25 - - o Library - ========= - o General - --------- - * Fill-value forward-compatibility with release 1.5 was added. SLU - - 2002/04/11 - * A new query function H5Tget_member_index has been added for compound - and enumeration data types. This function retrieves a member's index - by name. SLU - 2002/04/05 - * Added serial multi-gigabyte file size test. "test/big -h" shows - the help page. AKC - 2002/03/29 - - o APIs - ------ - * The F90 subroutines h5dwrite_f, h5dread_f, h5awrite_f, and h5aread_f - were overloaded with a "dims" argument of type INTEGER(HSIZE_T) to - specify the size of the array. We recommend using these subroutines - with the new type; module subroutines that accept "dims" as an i - INTEGER array of size 7 will be deprecated in release 1.6. - EIP - 2002/05/06 - - o Performance - ------------- - * Added internal "small data" aggregation, which can reduce the number of - actual I/O calls made, improving performance. QAK - 2002/06/05 - * Improved internal metadata aggregation, which can reduce the number of - actual I/O calls made, improving performance. Additionally, this can - reduce the size of files produced. QAK - 2002/06/04 - * Improved internal metadata caching, which can reduce the number of - actual I/O calls made by a substantial amount, improving - performance. QAK - 2002/06/03 - - - o Parallel library - ================== - * Fixed bug in parallel I/O routines where a collective I/O which used - MPI derived types, followed by an independent I/O would cause the library - to hang. QAK 2002/06/24 - * Added environment variable flag to control whether creating MPI derived - types is preferred or not. This can affect performance, depending on - which way the MPI-I/O library is optimized. The default is set to - prefer MPI derived types for collective raw data transfers; setting the - HDF5_MPI_PREFER_DERIVED_TYPES environment variable to "0" (i.e.: - "setenv HDF5_MPI_PREFER_DERIVED_TYPES 0") changes the preference to avoid - using them whenever possible. QAK - 2002/06/19 - * Changed MPI I/O routines to avoid creating MPI derived types (and thus - needing to set the file view) for contiguous selections within datasets. - This should result in some performance improvement for those types of - selections. QAK - 2002/06/18 - * Changed MPI type support for collective I/O to be enabled by default. - This can be disabled by setting the HDF5_MPI_OPT_TYPES environment - variable to the value "0". QAK - 2002/06/14 - * Allowed chunks in chunked datasets to be cached when parallel file is - opened for read-only access (bug #709). QAK - 2002/06/10 - * Changed method for allocating chunked dataset blocks to only allocate - blocks that don't already exist, instead of attempting to create all the - blocks all the time. This improves performance for chunked - datasets. QAK - 2002/05/17 - * Allowed the call to MPI_File_sync to be avoided when the file is going to - immediately be closed, improving performance. QAK - 2002/05/13 - * Allowed the metadata writes to be shared among all processes, easing the - burden on process 0. QAK - 2002/05/10 - - - o Tools - ======= - * h5redeploy utility was added. It updates HDF5 compiler tools - after the HDF5 software has been installed in a new location. - - - o Support for new platforms and languages - ========================================= - * Parallel Fortran Library works now on HP-UX B.11.00 Sys V. - EIP - 2002/05/06 - * Intel C++ and F90 compilers Version 6.0 are supported on Linux 2.4. - * Intel C++ compilers Version 6.0 are supported on Windows 2000. - - - o Misc. - ========================================= - * zlib has been moved out of the Windows source release. Users should go to - the ZLIB homepage(http://www.zlib.org) to download the corresponding - zlib library. - * The Windows binary release is built with the old version of the zlib - library. We expect users to use zlib 1.1.4 to build with the source - release. - * In the Windows-specific install document, we specify how to test backward - compatibility. However, in this release, we are not testing the backward - compatibility of HDF5. - - -Bug Fixes since HDF5-1.4.3 Release -================================== - * Fixed bug in chunking routines where they were using internal allocation - free routines, instead of malloc/free, preventing user filters from - working correctly. Chunks are now allocated/freed with malloc/free and - so should the chunks in user filters. QAK 2002/06/18 - * Fixed bug where regular hyperslab selection could get incorrectly - transferred when the number of elements in a row did not fit evenly - into the buffer provided. QAK 2002/06/12 - * Fixed bug (#499) which allowed an "empty" compound or enumerated datatype - (one with no members) to be used to create a dataset or to be committed - to a file. QAK - 2002/06/11 - * Fixed bug (#777) which allowed a compound datatype to be inserted into - itself. QAK - 2002/06/10 - * Fixed bug (#789) where creating 1-D dataset region reference caused the - library to go into infinite loop. QAK - 2002/06/10 - * Fixed bug (#699, fix provided by a user) where a scalar dataspace was - written to the file and then subsequently queried with the - H5Sget_simple_extent_type function; type was reported as H5S_SIMPLE - instead of H5S_SCALAR. EIP - 2002/06/04 - * Clear symbol table node "dirty" flag when flushing symbol tables to - disk, to reduce I/O calls made & improve performance. QAK - 2002/06/03 - * Fixed bug where an object's header could get corrupted in certain - obscure situations when many objects were created in the - file. QAK - 2002/05/31 - * Fixed bug where read/write intent in file IDs created with H5Freopen - was not being kept the same as the original file. QAK - 2002/05/14 - * Fixed bug where selection offsets were not being used when iterating - through point and hyperslab selections with - H5Diterate(). QAK - 2002/04/29 - * Fixed bug where the data for several level deep nested compound & - variable-length datatypes used for datasets were getting corrupted when - written to the file. QAK - 2002/04/17 - * Fixed bug where selection offset was being ignored for certain hyperslab - selections when optimized I/O was being performed. QAK - 2002/04/02 - * Fixed limitation in h5dumper with object names which reached over 1024 - characters in length. We can now handle arbitrarily larger sizes for - object names. BW - 2002/03/29 - * Fixed bug where variable-length string type did not behave as a - string. SLU - 2002/03/28 - * Fixed bug in H5Gget_objinfo() which was not setting the 'fileno' - of the H5G_stat_t struct. QAK - 2002/03/27 - * Fixed data corruption bug in hyperslab routines when contiguous - hyperslab that spans entire dimension and is larger than type - conversion buffer is attempted to be read. QAK - 2002/03/26 - - -Performance Improvements -======================== - This release of the HDF5 library has been extensively tuned to improve -performance, especially to improve parallel I/O performance. - Most of the specific information for particular performance improvements -is mentioned in the "New Features" and "Bug Fixes since HDF5-1.4.3" sections -of this document, but in general, the library should make fewer and larger -I/O requests when accessing a file. Additionally, improvements to the parallel -I/O portions of the library should have reduced the communications and barriers -used in various internal algorithms, improving the performance of the library. - However, with the extensive changes to some portions of the library that -were required for these improvements, some errors or unanticipated results may -have been introduced also. Please report any problems encountered to our -support team at hdfhelp@ncsa.uiuc.edu. - Hopefully these improvements will benefit all HDF5 applications, but if -there are particular I/O patterns that appear to be slower than necessary, -please send e-mail to hdfhelp@ncsa.uiuc.edu with a sample program showing the -problem behavior; we will look into the issue to see if it is possible to -address it. - - -Documentation -============= - * Documentation was updated for the hdf5-1.4.4 release. - * A new "HDF5 User's Guide" is under development.

This is planned to be fixed in the next release. - - * On the SV1, the h5ls test fails due to a difference between the - SV1 printf precision and the printf precision on other platforms. - - * The h5dump tests may fail to match the expected output on some - platforms (e.g. SP2 parallel, Windows) where the error messages - directed to "stderr" do not appear in the "right order" with output - from stdout. This is not an error. - - * The --enable-static-exec configure flag fails to compile for HP-UX - 11.00 platforms. - - * The executables are always dynamic on IRIX64 6.5(64 and n32) and - IRIX 6.5 even if they are configured with --enable-static-exec. - - * IRIX 6.5 fails to compile if configured with --enable-static-exec. - - * The HDF5_MPI_OPT_TYPES optimization code in the parallel HDF5 will cause - a hang in some cases when chunked storage is used. This is now set to - be off by default. One may turn it on by setting the environment - variable HDF5_MPI_OPT_TYPES to a non-zero value such as 1. - - * On IA32 and IA64 systems, if you use a compiler other than GCC (such as - Intel's ecc or icc compilers), you will need to modify the generated - "libtool" program after configuration is finished. On or around line 104 - of the libtool file, there are lines which look like: - - # How to pass a linker flag through the compiler. - wl="" - - Change these lines to this: - - # How to pass a linker flag through the compiler. - wl="-Wl," - - * To build the Fortran library using Intel compilers, one has to - x modify the source code in the fortran/src directory to remove the - !DEC and !MS compiler directives. - x The build will fail in the fortran/test directory and then in the - fortran/examples directory; to proceed, edit the work.pcl files in - those directories to contain two lines - - work.pc - ../src/work.pc - - * To build the Fortran library on IA64 use - setenv CC "ecc -DIA64" - setenv F9X "efc -cl,work.pcl" - before running configure and see the steps described above. - - -%%%%1.4.3%%%% Release Information for hdf5-1.4.3 (18/Februaru/02) - -11. Release information for HDF5 version 1.4.3 -============================================================================== - - -INTRODUCTION - -This document describes the differences between HDF5-1.4.2 and -HDF5-1.4.3, and contains information on the platforms tested and -known problems in HDF5-1.4.2.

Note that the current - Attribute::getName, that returns "string", is still available. - * Following the change in the C library, the corresponding C++ API - is changed from: - void Attribute::write( const DataType& mem_type, void *buf ) - to: - void Attribute::write( const DataType& mem_type, const void *buf ) - - o Performance - ------------- - * Added perform programs to test the HDF5 library performance. Programs - are installed in directory perform/. - * Improved performance of byte-swapping during data conversions. - * Improved performance of single, contiguous hyperslabs when reading or - writing. - * Added support to read/write portions of chunks directly, if they are - uncompressed and too large to cache. This should speed up I/O on chunked - datasets for a few more cases. -QAK, 1/31/02 - - o Parallel Library - ================== - * Parallel C HDF5 now works on HP-UX platforms, Compaq clusters, - Linux clusters, Cplants (alpha-linux clusters). - - o Tools - ======= - * A helper script called ``h5cc'', which helps compilation of HDF5 - programs, is now distributed with HDF5. See the reference manual - for information on how to use this feature. - * The H5Dumper can now dump comments associated with groups. -WCW 01-05-02 - - o Support for new platforms and languages - ========================================= - * HDF5 C++ Library is supported on Windows platforms (shared and static) - * HDF5 F90 shared library is supported on Windows platforms. - * HDF5 C Library is supported on IA32 and IA64 platforms. - - - -Bug Fixes since HDF5-1.4.2 Release -================================== - - * Fixed a bug when reading chunked datasets where the edge of the dataset - would be incorrectly detected and generate an assertion failure. - * Fixed a bug where reading an entire dataset wasn't being handled - optimally when the dataset had unlimited dimensions. Dataset is read - in a single low-level I/O now, instead of being broken into separate - pieces internally. - * Fixed a bug where reading or writing chunked data which needed datatype - conversion could result in data values getting corrupted. - * Fixed a bug where appending a point selection to the current selection - would not actually append the point when there were no points defined - currently. - * Fixed a bug where 'or'ing a hyperslab with a 'none' selection would - fail. Now adds that hyperslab as the first hyperlab in the selection. - * Fixed a bug in the 'big' test where quota limits weren't being detected - properly if they caused close() to fail. - * Fixed a bug in internal B-tree code where a B-tree was not being copied - correctly. - * Fixed an off-by-one error in H5Sselect_valid when hyperslab selections - which would allow hyperslab selections which overlapped the edge of the - selection by one element as valid. - * Fixed the internal macros used to encode & decode file metadata, to avoid - an unaligned access warning on IA64 machines. - * Corrected behavior of H5Tinsert to not allow compound datatype fields to - be inserted past the end of the datatype. - * Retired the DPSS virtual file driver (--with-gridstorage configure - option). - * Fixed bug where variable-length datatypes for attributes was not working - correctly. - * Fixed bug where raw data re-allocated from the free-list would sometimes - overlap with the metadata accumulator and get corrupted. QAK - 1/23/02 - * Fixed bug where a preempted chunk in the chunk data could still be - used by an internal pointer and cause an assertion failure or core - dump.

Release Information for hdf5-1.4.2 -================================================================= - - -INTRODUCTION - -This document describes the differences between HDF5-1.4.1 and -HDF5-1.4.2, and contains information on the platforms tested and -known problems in HDF5-1.4.2. - -The HDF5 documentation can be found on the NCSA ftp server -(ftp.ncsa.uiuc.edu) in the directory: - - /HDF/HDF5/docs/ - -For more information look at the HDF5 home page at: - - http://hdf.ncsa.uiuc.edu/HDF5/ - -If you have any questions or comments, please send them to: - - hdfhelp@ncsa.uiuc.edu - - -CONTENTS - -- New Features -- Bug Fixes since HDF5-1.4.1 -- Documentation -- Platforms Tested -- Supported Configuration Features -- Known Problems - - -New Features -============ - - * File sizes greater than 2GB are now supported on Linux systems with - version 2.4.x or higher kernels. - * Added a global string variable H5_lib_vers_info_g which holds the - HDF5 library version information. This can be used to identify - an hdf5 library or hdf5 application binary. - Also added a verification of the consistency between H5_lib_vers_info_g - and other version information in the source code. - * Parallel HDF5 now runs on the HP V2500 and HP N4000 machines. - * F90 API: - - Added aditional parameter "dims" to the h5dread_f/h5dwrite_f and - h5aread_f/h5awrite_f subroutines. This parameter is a 1-D array - of size 7 and contains the sizes of the data buffer dimensions. - This change enables portability between Windows and UNIX platforms. - In previous versions of the F90 APIs, the data buffer parameters of - the above functions were declared as assumed-shape arrays, which - were passed to the C functions by a descriptor. There is no - portable means, however, of passing descriptors from F90 to C, - causing portability problems between Windows and UNIX and among - UNIX platforms. With this change, the data buffers are assumed- - size arrays, which can be portably passed to the C functions. - * F90 static library is available on Windows platforms. - See INSTALL_Windows_withF90.txt for details. - * F90 APIs are available on HPUX 11.00 and 10.20 and IBM SP platforms. - * H5 <-> GIF convertor has been added. This is available under - tools/gifconv. The convertor supports the ability to create animated - gifs as well. - * Verified correct operation of library on Solaris 2.8 in both 64-bit and - 32-bit compilation modes. See INSTALL document for instructions on - compiling the distribution with 64-bit support. - * Added support for the Metrowerks Code Warrior compiler for Windows. - * For H4->H5 converter utility, added a new option to choose not to convert - HDF4 specified attributes(reference number, class) into HDF5 attributes. - * Added support chunking and compression in SDS and image in H4->H5 converter. - Currently HDF5 only supports gzip compression, so by default an HDF4 file - with any other compression method will be converted into an HDF5 file in - gzip compression. - * correct the order or reading HDF4 image array in H4->H5 conversion. - * Added new parallel hdf5 tests in t_mpi. The new test checks if the - filesystem or the MPI-IO can really handle greater than 2GB files. - If it fails, it prints information message only without failing the - test. - * Added a parallel HDF5 example examples/ph5example.c to illustrate - the basic way of using parallel HDF5. - * Added a new public macro, H5_VERS_INFO, which is a string holding - the HDF5 library version information. This string is also compiled - into all HDF5 binary code which helps to identify the version information - of the binary code. One may use the Unix strings command on the binary - file and looks for the pattern "HDF5 library version". - * Added new checking in H5check_version() to verify the five HDF5 version - information macros (H5_VERS_MAJOR, H5_VERS_MINOR, H5_VERS_RELEASE, - H5_VERS_SUBRELEASE and H5_VERS_INFO) are consistent. - - -Bug Fixes since HDF5-1.4.1 Release -================================== - - * Fixed bug with non-zero userblock sizes causing raw data to not - write correctly. - * Fixed problems with Pablo build and linking with non-standard MPI I/O. - * Fixed build on Linux systems with --enable-static-exec flag. It now - works correctly. - * IMPORTANT: Fixed file metadata corruption bug which could cause - metadata data loss in certain situations. - * The allocation by alignment (H5Pset_alignment) feature code somehow - got dropped in some 1.3.x version. Re-implemented it with "new and - improved" algorithm. It keeps track of "wasted" file-fragment in - the free-list too. - * Removed limitation that the data transfer buffer size needed to be - set for datasets whose dimensions were too large for the 'all' - selection code to handle. Any size dimensioned datasets should be - handled correctly now. - * Changed behavior of H5Tget_member_type to correctly emulate HDF5 v1.2.x - when --enable-hdf5v1_2 configure flag is enabled. - * Added --enable-linux-lfs flag to allow more control over whether to - enable or disable large file support on Linux. - * Fixed various bugs releated to SDS dimensional scale conversions in H4->H5 - converter. - * Fixed a bug to correctly convert HDF4 objects with fill value into HDF5. - * Fixed a bug of H5pubconf.h causing repeated definitions if it is included - more than once. hdf5.h now includes H5public.h which includes - H5pubconf.h. Applications should #include hdf5.h which handles multiple - inclusion correctly. - * Fixed H5FDmpio.h to be C++ friendly by making Parallel HDF5 API's to be - external to C++. - * Fixed a bug in H5FD_mpio_flush() that might result in negative file seek - if both MPIO and Split-file drivers are used together. - - - -Documentation -============= - - * The H5T_conv_t and H5T_cdata_t structures are now properly defined - in the H5Tregister entry in the "H5T" section of the "HDF5 Reference - Manual" and described in detail in section 12, "Data Conversions," in - the "Datatypes" chapter of the "HDF5 User's Guide." - * The new tools h52gif and gif2h5 have been added to the "Tools" section - of the Reference Manual. - * A "Freespace Management" section has been added to the "Performance" - chapter of the User's Guide. - * Several user-reported bugs have been fixed since Release 1.4.1. - * The "HDF5 Image and Palette Specification" (in the "HDF5 Application - Developer's Guide") has been heavily revised. Based on extensive user - feedback and input from visualization software developers, Version 1.2 - of the image specification is substantially different from prior - versions. - - -Platforms Tested -================ - - AIX 4.3.3.0 (IBM SP powerpc) xlc 3.6.6.0 - mpcc_r 3.6.6.0 - xlf 07.01.0000.0002 - mpxlf 07.01.0000.0002 - AIX 4.3 (IBM SP RS6000) C for AIX Compiler, Version 5.0.2.0 - xlf 7.1.0.2 - poe 2.4.0.14 (includes mpi) - Cray T3E sn6711 2.0.5.49a Cray Standard C Version 6.5.0.1 - Cray SV1 10.0.0.2 Cray Standard C Version 6.5.0.1 - Cray Fortran Version 3.5.0.1 - FreeBSD 4.3 gcc 2.95.3 - g++ 2.95.3 - HP-UX B.10.20 HP C HP92453-01 A.10.32.30 - HP F90 v2.3 - HP-UX B.11.00 HP C HP92453-01 A.11.01.20 - HP F90 v2.4 - HP-UX B.11.00 SysV HP C HP92453-01 A.11.01.20 - HP F90 v2.4 - IRIX 6.5 MIPSpro cc 7.30 - IRIX64 6.5 (64 & n32) MIPSpro cc 7.3.1.2m - Linux 2.4.4 gcc 2.95.3 - g++ 2.95.3 - Linux 2.2.18smp gcc 2.95.2 - gcc 2.95.2 with mpich 1.2.1 - g++ 2.95.2 - pgf90 3.2-4 - OSF1 V4.0 DEC-V5.2-040 on Digital UNIX V4.0 (Rev 564) - Digital Fortran 90 V4.1-270 - SunOS 5.6 WorkShop Compilers 5.0 98/12/15 C 5.0 - (Solaris 2.6) WorkShop Compilers 5.0 98/10/25 FORTRAN 90 - 2.0 Patch 107356-04 - SunOS 5.7 WorkShop Compilers 5.0 98/12/15 C 5.0 - (Solaris 2.7) Workshop Compilers 5.0 98/12/15 C++ 5.0 - Workshop Compilers 5.0 98/10/25 FORTRAN 90 - 2.0 Patch 107356-04 - SunOS 5.8/32 Sun WorkShop 6 update 1 C 5.2 2000/09/11 - (Solaris 2.8) Sun WorkShop 6 update 1 Fortran 95 6.1 - 2000/09/11 - Sun WorkShop 6 update 1 C++ 5.2 2000/09/11 - SunOS 5.8/64 Sun WorkShop 6 update 1 C 5.2 2000/09/11 - (Solaris 2.8) Sun WorkShop 6 update 1 Fortran 95 6.1 - 2000/09/11 - Sun WorkShop 6 update 1 C++ 5.2 2000/09/11 - TFLOPS r1.0.4 v4.0.7 i386 pgcc Rel 3.1-4i with mpich-1.2.1 with - local modifications - Windows 2000 (NT5.0) MSVC++ 6.0 - Windows NT4.0 MSVC++ 6.0 - DEC Visual Fortran 6.0 - Windows NT4.0 Code Warrior 6.0 - Windows 98 MSVC++ 6.0 - DEC Visual Fortran 6.0 - - -Supported Configuration Features Summary -======================================== - - In the tables below - y = tested and supported - n = not supported or not tested in this release - x = not working in this release - ( ) = footnote appears below second table - - - Platform C C F90 F90 C++ Shared zlib Tools - parallel parallel libraries - (5) - Solaris2.6 y n y n y y y y - Solaris2.7 y y (1) y n y y y y - Solaris2.8 64 y n n n y y y y - Solaris2.8 32 y n y n y y y y - IRIX6.5 y y (1) n n n y y y - IRIX64_6.5 64 y y (2) y y n y y y - IRIX64_6.5 32 y y (2) n n n y y y - HPUX10.20 y n y n n y y y - HPUX11.00 y n y n n y y y - HPUX11 SysV y n y n n y y y - DECOSF y n y n n y y y - T3E y y y y n n y y - SV1 y n y n n n y y - TFLOPS y y (1) n n n n y y (4) - AIX-4.3 SP2 y y y y n n y n - AIX-4.3 SP3 y y y y n n y n - Win2000 y n n n n y y y - Win98 y n y n n y y y - WinNT y n y n n y y y - WinNT CW y n n n n n y y - FreeBSD y n n n y y y y - Linux 2.2 y y (1) y n y y y y - Linux 2.4 y y (1) n n y y y y - - - Platform 1.2 static- Thread- SRB GASS STREAM- - compatibility exec safe VFD - Solaris2.6 y x n n n y - Solaris2.7 y x y n n y - Solaris2.8 64 y y n n n y - Solaris2.8 32 y x n n n y - IRIX6.5 y x y n n y - IRIX64_6.5 64 y x n n n y - IRIX64_6.5 32 y x n n n y - HPUX10.20 y y n n n y - HPUX11.00 y x n n n y - HPUX11 SysV y x n n n y - DECOSF y y n n n y - T3E y y n n n y - SV1 y y n n n y - TFLOPS y y n n n n - AIX-4.3 SP2 y y (3) n n n y - AIX-4.3 SP3 y y n n n y - Win2000 y y n n n n - Win98 n y n n n n - WinNT y y n n n n - WinNT CW n n n n n n - FreeBSD y y n n n y - Linux 2.2 y y y n n y - Linux 2.4 y y y n n y - - - Footnotes: (1) Using mpich. - (2) Using mpt and mpich. - (3) When configured with static-exec enabled, tests fail - in serial mode. - (4) No HDF4-related tools. - (5) Shared libraries are provided only for the C library. - - -Known Problems -============== - - * When a dataset with the variable-legth datatype is overwritten, - the library can develop memory leaks that cause the file to become - unnecessarily large.

It also provides an API for user defined file drivers. - * New features added to snapshots. Use 'snapshot help' to see a - complete list of features. - * Improved configure to detect if MPIO routines are available when - parallel mode is requested. - * Added Thread-Safe support. Phase I implemented. See: - - http://hdf.ncsa.uiuc.edu/HDF5/papers/mthdf/MTHDFpaper.htm - - for more details. - * Added data sieve buffering to raw data I/O path. This is enabled - for all VFL drivers except the mpio & core drivers. Setting the - sieve buffer size is controlled with the new API function, - H5Pset_sieve_buf_size(), and retrieved with H5Pget_sieve_buf_size(). - * Added new Virtual File Driver, Stream VFD, to send/receive entire - HDF5 files via socket connections. - * As parts of VFL, HDF-GASS and HDF-SRB are also added to this - release. To find out details, please read INSTALL_VFL file. - * Increased maximum number of dimensions for a dataset (H5S_MAX_RANK) - from 31 to 32 to align with HDF4 & netCDF. - * Added 'query' function to VFL drivers. Also added 'type' parameter to - VFL 'read' & 'write' calls, so they are aware of the type of data - being accessed in the file. Updated the VFL document also. - * A new h4toh5 utility, to convert HDF4 files to analogous HDF5 files. - * Added a new array datatype to the datatypes which can be created. - Removed "array fields" from compound datatypes (use an array datatype - instead). - * Parallel HDF5 works correctly with mpich-1.2.1 on Solaris, SGI, Linux. - * You can now install the HDF5 documentation using the - ``make install-doc'' command. The documentation is installed in the - $(prefix)/doc directory where $(prefix) is the prefix specified by - the (optional) ``--prefix'' flag during configuration. - * HDF5 can operate correctly in the OpenMP environment in a limited way. - Check doc/html/TechNotes/openmp-hdf5.html for details. - - -h4toh5 Utility -============== - The h4toh5 utility is a new utility that converts an HDF4 file to an - HDF5 file. For details, see the document, "Mapping HDF4 Objects to - HDF5 Objects": - http://hdf.ncsa.uiuc.edu/HDF5/papers/H4-H5MappingGuidelines.pdf - - Known Bugs: - - The h4toh5 utility produces images that do not correctly conform - to the HDF5 Image and Palette Specification. - - http://hdf.ncsa.uiuc.edu/HDF5/doc/ImageSpec.html - - Several required HDF5 attributes are omitted, and the dataspace - is reversed (i.e., the ht. and width of the image dataset is - incorrectly described.) For more information, please see: - - http://hdf.ncsa.uiuc.edu/HDF5/H5Image/ImageDetails.html - - This bug has been fixed for the snapshot of hdf5 1.4 release. March 12th,2001 - - Known Limitations of the h4toh5 release - --------------------------------------------- - - 1. Error handlings - - h4toh5 utility will print out an error message when an error occurs. - - 2. String Datatype - - HDF4 has no 'string' type. String valued data are usually defined as - an array of 'char' in HDF4. The h4toh5 utility will generally map - these to HDF5 'String' types rather than array of char, with the - following additional rules: - - * For the data of an HDF4 SDS, image, and palette, if the data is - declared 'DFNT_CHAR8' it will be assumed to be integer and will - be an H5T_INTEGER type. - * For attributes of any HDF4 object, data of type 'DFNT_CHAR8' - will be converted to an HDF5 'H5T_STRING' type. - * For an HDF4 Vdata, it is difficult to determine whether data - of type 'DFNT_CHAR8' is intended to be bytes or characters. The - h4toh5 utility will consider them to be C characters, and will - convert them to an HDF5 'H5T_STRING' type. - - - 3. Compression, Chunking and External Storage - - Chunking is supported, but compression and external storage is not. - - An HDF4 object that uses chunking will be converted to an HDF5 file - with analogous chunked storage. - - An HDF4 object that uses compression will be converted to an - uncompressed HDF5 object. - - An HDF4 object that uses external storage will be converted to an - HDF5 object without external storage. - - 4. Memory Use - - This version of the h4toh5 utility copies data from HDF4 objects - in a single read followed by a single write to the HDF5 object. For - large objects, this requires a very large amount of memory, which may - be extremely slow or fail on some platforms. - - Note that a dataset that has only been partly written will - be read completely, including uninitialized data, and all the - data will be written to the HDF5 object. - - 5. Platforms - - The h4toh5 utility requires HDF5-1.4.0 and HDF4r1.4 - - h4toh5 utility has been tested on all platforms listed below (see - section "Platforms Tested") except TFLOPS. - - -F90 Support -=========== - This is the first release of the HDF5 Library with fully integrated - F90 API support. The Fortran Library is created when the - --enable-fortran flag is specified during configuration. - - Not all F90 subroutines are implemented. Please refer to the HDF5 - Reference Manual for more details. - - F90 APIs are available for the Solaris 2.6 and 2.7, Linux, DEC UNIX, - T3E, SV1 and O2K (64 bit option only) platforms. The Parallel version of - the HDF5 F90 Library is supported on the O2K and T3E platforms. - - Changes since the last prototype release (July 2000) - ---------------------------------------------------- - * h5open_f and h5close_f must be called instead of h5init_types and - h5close_types. - - * The following subroutines are no longer available: - - h5pset_xfer_f - h5pget_xfer_f - h5pset_mpi_f - h5pget_mpi_f - h5pset_stdio_f - h5pget_stdio_f - h5pset_sec2_f - h5pget_sec2_f - h5pset_core_f - h5pget_core_f - h5pset_family_f - h5pget_family_f - - * The following functions have been added: - - h5pset_fapl_mpio_f - h5pget_fapl_mpio_f - h5pset_dxpl_mpio_f - h5pget_dxpl_mpio_f - - * In the previous HDF5 F90 releases, the implementation of object - references and dataset region references was not portable. This - release introduces a portable implementation, but it also introduces - changes to the read/write APIs that handle references. If object or - dataset region references are written or read to/from an HDF5 file, - h5dwrite_f and h5dread_f must use the extra parameter, n, for the - buffer size: - - h5dwrite(read)_f(dset_id, mem_type_id, buf, n, hdferr, & - ^^^ - mem_space_id, file_space_id, xfer_prp) - - For other datatypes the APIs were not changed. - - -C++ Support -=========== - This is the first release of the HDF5 Library with fully integrated - C++ API support. The HDF5 C++ library is built when the --enable-cxx - flag is specified during configuration. - - Check the HDF5 Reference Manual for available C++ documentation. - - C++ APIs are available for Solaris 2.6 and 2.7, Linux, and FreeBSD. - - -Pablo Support -============= - This version does not allow proper building of the Pablo-instrumented - version of the library. A version supporting the pablo build is - available on the Pablo Website at - www-pablo.cs.uiuc.edu/pub/Pablo.Release.5/HDFLibrary/hdf5_v1.4.tar.gz - - -Bug Fixes since HDF5-1.2.0 -========================== - -Library -------- - * The function H5Pset_mpi is renamed as H5Pset_fapl_mpio. - * Corrected a floating point number conversion error for the Cray J90 - platform. The error did not convert the value 0.0 correctly. - * Error was fixed which was not allowing dataset region references to - have their regions retrieved correctly. - * Corrected a bug that caused non-parallel file drivers to fail in - the parallel version. - * Added internal free-lists to reduce memory required by the library - and H5garbage_collect API function - * Fixed error in H5Giterate which was not updating the "index" - parameter correctly. - * Fixed error in hyperslab iteration which was not walking through the - correct sequence of array elements if hyperslabs were staggered in a - certain pattern - * Fixed several other problems in hyperslab iteration code. - * Fixed another H5Giterate bug which was causes groups with large - numbers of objects in them to misbehave when the callback function - returned non-zero values. - * Changed return type of H5Aiterate and H5A_operator_t typedef to be - herr_t, to align them with the dataset and group iterator functions. - * Changed H5Screate_simple and H5Sset_extent_simple to not allow - dimensions of size 0 with out the same dimension being unlimited. - * QAK - 4/19/00 - Improved metadata hashing & caching algorithms to - avoid many hash flushes and also remove some redundant I/O when - moving metadata blocks in the file. - * The "struct(opt)" type conversion function which gets invoked for - certain compound datatype conversions was fixed for nested compound - types. This required a small change in the datatype conversion - function API. - * Re-wrote lots of the hyperslab code to speed it up quite a bit. - * Added bounded garbage collection for the free lists when they run - out of memory and also added H5set_free_list_limits API call to - allow users to put an upper limit on the amount of memory used for - free lists. - * Checked for non-existent or deleted objects when dereferencing one - with object or region references and disallow dereference. - * "Time" datatypes (H5T_UNIX_D*) were not being stored and retrieved - from object headers correctly, fixed now. - * Fixed H5Dread or H5Dwrite calls with H5FD_MPIO_COLLECTIVE requests - that may hang because not all processes are transfer the same amount - of data. (A.K.A. prematured collective return when zero amount data - requested.) Collective calls that may cause hanging is done via the - corresponding MPI-IO independent calls. - * If configure with --enable-debug=all, couple functions would issue - warning messages to "stderr" that the operation is expensive time-wise. - This messed up applications (like testings) that did not expect the - extra output. It is changed so that the warning will be printed only - if the corresponding Debug key is set. - -Configuration -------------- - * The hdf5.h include file was fixed to allow the HDF5 Library to be - compiled with other libraries/applications that use GNU autoconf. - * Configuration for parallel HDF5 was improved. Configure now attempts - to link with libmpi.a and/or libmpio.a as the MPI libraries by - default. It also uses "mpirun" to launch MPI tests by default. It - tests to link MPIO routines during the configuration stage, rather - than failing later as before. One can just do "./configure - --enable-parallel" if the MPI library is in the system library. - * Added support for pthread library and thread-safe option. - * The libhdf5.settings file shows the correct machine byte-sex. - * Added option "--enable-stream-vfd" to configure w/o the Stream VFD. - For Solaris, added -lsocket to the LIBS list of libraries. - -Tools ------ - * h5dump now accepts both short and long command-line parameters: - -h, --help Print a usage message and exit - -B, --bootblock Print the content of the boot block - -H, --header Print the header only; no data is displayed - -i, --object-ids Print the object ids - -V, --version Print version number and exit - -a P, --attribute=P Print the specified attribute - -d P, --dataset=P Print the specified dataset - -g P, --group=P Print the specified group and all members - -l P, --soft-link=P Print the value(s) of the specified soft link - -o F, --output=F Output raw data into file F - -t T, --datatype=T Print the specified named data type - -w #, --width=# Set the number of columns - - P - is the full path from the root group to the object. - T - is the name of the data type. - F - is a filename. - # - is an integer greater than 1. - * A change from the old way command line parameters were interpreted - is that multiple attributes, datasets, groups, soft-links, and - object-ids cannot be specified with just one flag but you have to - use a flag with each object. I.e., instead of doing this: - - h5dump -a /attr1 /attr2 foo.h5 - - do this: - - h5dump -a /attr1 -a /attr2 foo.h5 - - The cases are similar for the other object types. - * h5dump correctly displays compound datatypes. - * Corrected an error in h5toh4 which did not convert the 32bits - int from HDF5 to HDF4 correctly for the T3E platform. - * h5dump correctly displays the committed copy of predefined types - correctly. - * Added an option, -V, to show the version information of h5dump. - * Fixed a core dumping bug of h5toh4 when executed on platforms like - TFLOPS. - * The test script for h5toh4 used to not able to detect the hdp - dumper command was not valid. It now detects and reports the - failure of hdp execution. - * Merged the tools with the 1.2.2 branch. Required adding new - macros, VERSION12 and VERSION13, used in conditional compilation. - Updated the Windows project files for the tools. - * h5dump displays opaque and bitfield data correctly. - * h5dump and h5ls can browse files created with the Stream VFD - (eg. "h5ls <hostname>:<port>"). - * h5dump has a new feature "-o <filename>" which outputs the raw data - of the dataset into ascii text file <filename>. - * h5toh4 used to converts hdf5 strings type to hdf4 DFNT_INT8 type. - Corrected to produce hdf4 DFNT_CHAR type instead. - * h5dump and h5ls displays array data correctly. - - -Bug Fixes since HDF5-1.4.0-beta2 -================================ - * Fixed a bug in the conversion from a little endian double to a big - endian float in some special cases. - * Corrected configuration error which was not including compression - support correctly. - * Cleaned up lots of warnings. - * Changed a few h5dump command line switches and added long versions of - the switches. - * Changed parameters for H5Tconvert, H5Pset_bufer and H5Pget_buffer from - size_t to hsize_t - * Fixed fairly obscure bug in hyperslab I/O which could (in rare cases) - not copy all the data during a transfer. - * Removed ragged array code from library. - * F90 library and module files are installed properly now on all supported - platforms. - - -Bug Fixes since HDF5-1.4.0 Release -================================== - - * Fixed bug with contiguous hyperslabs not being detected, causing - slower I/O than necessary. - * Fixed bug where non-aligned hyperslab I/O on chunked datasets was - causing errors during I/O - * Implemented XML support in h5dump. - - -Documentation -============= - * A new document summarizing the changes in the library leading up to - the current release has been added: - HDF5 Software Changes from Release to Release - This document is in the Application Developer's Guide and is of - particular interest to developers who must keep an application - synchronized with the library. - * The documentation for the Fortran90 and C++ APIs is linked to the - opening page of the Reference Manual. Fortran90 functions are - individually referenced from the corresponding C functions through- - out the Reference Manual. - * User's Guide and Reference Manual were updated to reflect changed - function syntax and to fix reported bugs. - * Functions that are new at this release were added to the Reference - Manual. - * Functions that have been removed from the library were removed from - the User's Guide and the Reference Manual. - * PostScript and PDF versions of the Release 1.4 document set are - not available at the time of Release 1.4.0. - - -Platforms Tested -================ - AIX 4.3.3.0 (IBM SP powerpc) xlc 3.6.6 - mpcc_r 3.6.6 - Cray T3E sn6711 2.0.5.45 Cray Standard C Version 6.4.0.0 - Cray Fortran Version 3.4.0.2 - Cray SV1 sn9605 10.0.0.7 Cray Standard C Version 6.4.0.0 - Cray Fortran Version 3.4.0.2 - FreeBSD 4.2 gcc 2.95.2 - g++ 2.95.2 - HP-UX B.10.20 HP C HP92453-01 A.10.32.30 - HP-UX B.11.00 HP C HP92453-01 A.11.00.13 - IRIX 6.5 MIPSpro cc 7.30 - mpich-1.2.1 - IRIX64 6.5 (64 & n32) MIPSpro cc 7.3.1m - mpt.1.4.0.2 - mpich-1.2.1 - Linux 2.2.16-3smp gcc-2.95.2 - g++ 2.95.2 - pgf90 3.1-3 - mpich-1.2.1 - OSF1 V4.0 DEC-V5.2-040 - Digital Fortran 90 V4.1-270 - SunOS 5.6 WorkShop Compilers 5.0 98/12/15 C 5.0 - (Solaris 2.6) WorkShop Compilers 5.0 99/10/25 Fortran 90 - 2.0 Patch 107356-04 - Workshop Compilers 5.0 98/12/15 C++ 5.0 - SunOS 5.7 WorkShop Compilers 5.0 98/12/15 C 5.0 - (Solaris 2.7) WorkShop Compilers 5.0 99/10/25 Fortran 90 - 2.0 Patch 107356-04 - Workshop Compilers 5.0 98/12/15 C++ 5.0 - mpich-1.2.1 - SunOS 5.5.1 gcc-2.7.2 - (Solaris 2.5.1 (x86)) - TFLOPS r1.0.4 v4.0 mpich-1.2.1 with local changes - Windows NT4.0, 2000 (NT5.0) MSVC++ 6.0 - Windows 98 MSVC++ 6.0 - - -Supported Configuration Features Summary -======================================== - In the tables below - y = tested and supported - n = not supported or not working in this release - ( ) = footnote appears below table - - Platform C C F90 F90 C++ Shared zlib Tools - parallel parallel libraries - Solaris2.6 y n y n y y y y - Solaris2.7 y y (1) y n y y y y - Solarisx86 y n n n n y y y - IRIX6.5 y y (1) n n n n y y - IRIX64_6.5 64 y y (2) y y n y y y - IRIX64_6.5 32 y y (2) n n n y y y - HPUX10.20 y n n n n y y y - DECOSF y n y n n y y y - T3E y y y y n n y y - SV1 y n y n n n y y - TFLOPS y y (1) n n n n y y (4) - AIX-4.3 y y n n n n y n - Win2000 y n n n n y y y - Win98 y n n n n y y y - WinNT y n n n n y y y - FreeBSD y n n n y y y y - Linux y y (1) y n y y y y - - - Platform 1.2 static- Thread- SRB GASS STREAM- - compatibility exec safe VFD - Solaris2.6 y n n n n y - Solaris2.7 y n y n n y - Solarisx86 y n n n n y - IRIX6.5 y n y n n y - IRIX64_6.5 64 y n n n n y - IRIX64_6.5 32 y n n n n y - HPUX10.20 y y n n n y - DECOSF y y n n n y - T3E y y n n n y - SV1 y y n n n y - TFLOPS y y n n n n - AIX-4.3 y y (3) n n n y - Win2000 y y n n n n - Win98 y y n n n n - WinNT y y n n n n - FreeBSD y y n n n y - Linux y n y n n y - - Footnotes: (1) Using mpich. - (2) Using mpt and mpich. - (3) When configured with static-exec enabled, tests fail - in serial mode. - (4) No HDF4-related tools. - - -Known Problems -============== - * The stream-vfd test uses ip port 10007 for testing. If another - application is already using that port address, the test will hang - indefinitely and has to be terminated by the kill command. To try the - test again, change the port address in test/stream_test.c to one not - being used in the host. - - * The --enable-static-exec configure flag fails to compile for Solaris - platforms. This is due to the fact that not all of the system - libraries on Solaris are available in a static format. - - The --enable-static-exec configure flag also fails to correctly compile - on Linux platforms using the gcc-2.95.2 compiler. - - The --enable-static-exec configure flag also fails to correctly compile - on IBM SP2 platform for the serial mode. The parallel mode works fine - with this option. - - The compilation fails if configured with --enable-static-exec on IRIX 6.5. - - The executable files in hdf5/bin are dynamic-linked for IRIX64 6.5(64 and - n32 modes) and IRIX 6.5, even though they are compiled with static library. - - It is suggested that you don't use this option on these platforms - during configuration. - - * testhdf5 got bus error with configuration options --prefix and --with-hdf4 - on IRIX 6.5. - - * With the gcc 2.95.2 compiler, HDF 5 uses the `-ansi' flag during - compilation. The ANSI version of the compiler complains about not being - able to handle the `long long' datatype with the warning: - - warning: ANSI C does not support `long long' - - This warning is innocuous and can be safely ignored. - - * SunOS 5.6 with C WorkShop Compilers 4.2: Hyperslab selections will - fail if library is compiled using optimization of any level. - - * When building hdf5 tools and applications on windows platform, a linking - warning: defaultlib "LIBC" conflicts with use of other libs will appear - on debug version when running VC++6.0. This warning doesn't affect building - and testing hdf5 applications. We will continue investigating this. - - * h5toh4 converter fails two cases(tstr.h5 and tmany.h5) for release dll - version on windows 2000 and NT. The reason is possibly due to Windows NT - DLL convention on freeing memory. It seems that memory cannot be freed - across library or DLL. It is still under investigation. - - * HDF-GASS testings and testhdf5 in the test directory will get bus error if - the configured with --with-gass. - - * HDF-SRB testing got segmentation error on Solaris 2.7. - - * The Stream VFD was not tested yet under Windows. - It is not supported in the TFLOPS machine. - - * Shared library option is broken for IBM SP and some Origin 2000 platforms. - One needs to run ./configure with '--disable-shared --enable-static'. - - * The ./dsets tests failed in the TFLOPS machine if the test program, - dsets.c, is compiled with the -O option. The hdf5 library still works - correctly with the -O option. The test program works fine if it is - compiled with -O1 or -O0. Only -O (same as -O2) causes the test - program to fail. - - * Certain platforms give false negatives when testing h5ls: - - Solaris x86 2.5.1, Cray T3E and Cray J90 give errors during testing - when displaying object references in certain files. These are benign - differences due to the difference in sizes of the objects created on - those platforms. h5ls appears to be dumping object references - correctly. - - Cray J90 give errors during testing when displaying - some floating-point values. These are benign differences due to the - different precision in the values displayed and h5ls appears to be - dumping floating-point numbers correctly. - - * Before building HDF5 F90 Library from source on Crays (T3E and SV1) - replace H5Aff.f90, H5Dff.f90 and H5Pff.f90 files in the fortran/src - subdirectory in the top level directory with the Cray-specific files from - the ftp://ftp.ncsa.uiuc.edu/HDF/HDF5/hdf5-1.4.0/src/crayf90/ directory. - - * The h4toh5 utility produces images that do not correctly conform - to the HDF5 Image and Palette Specification. - - http://hdf.ncsa.uiuc.edu/HDF5/doc/ImageSpec.html - - Several required HDF5 attributes are omitted, and the dataspace - is reversed (i.e., the ht. and width of the image dataset is - incorrectly described.)

Changes from Release 1.0.0 to Release 1.0.1 -===================================================================== - -* [Improvement]: configure sets up the Makefile in the parallel tests - suit (testpar/) correctly. - -* [Bug-Fix]: Configure failed for all IRIX versions other than 6.3. - It now configures correctly for all IRIX 6.x version. - -* Released Parallel HDF5 - - Supported Features: - ------------------ - - HDF5 files are accessed according to the communicator and INFO - object defined in the property list set by H5Pset_mpi. - - Independent read and write accesses to fixed and extendable dimension - datasets. - - Collective read and write accesses to fixed dimension datasets. - - Supported Platforms: - ------------------- - - Intel Red - IBM SP2 - SGI Origin 2000 - - Changes In This Release: - ----------------------- - - o Support of Access to Extendable Dimension Datasets. - Extendable dimension datasets must use chunked storage methods. - A new function, H5Dextend, is created to extend the current - dimensions of a dataset. The current release requires the - MPI application must make a collective call to extend the - dimensions of an extendable dataset before writing to the - newly extended area. (The serial does not require the - call of H5Dextend. The dimensions of an extendable - dataset is increased when data is written to beyond the - current dimensions but within the maximum dimensions.) - The required collective call of H5Dextend may be relaxed - in future release. - - This release only support independent read and write accesses - to extendable datasets. Collective accesses to extendable - datasets will be implemented in future releases. - - o Collective access to fixed dimension datasets. - Collective access to a dataset can be specified in the transfer - property list argument in H5Dread and H5Dwrite. The current - release supports collective access to fixed dimension datasets. - Collective access to extendable datasets will be implemented in - future releases. - - o HDF5 files are opened according to Communicator and INFO object. - H5Dopen now records the communicator and INFO setup by H5Pset_mmpi - and pass them to the corresponding MPIO open file calls for - processing. - - o This release has been tested on IBM SP2, Intel Red and SGI Origin 2000 - systems. It uses the ROMIO version of MPIO interface for parallel - I/O supports. - - - -%%%%1.0.0%%%% Release Information for hdf5-1.0.0 - -3. Changes from the Beta 1.0.0 Release to Release 1.0.0 -==================================================================== - -* Added fill values for datasets. For contiguous datasets fill value - performance may be quite poor since the fill value is written to the - entire dataset when the dataset is created. This will be remedied - in a future version. Chunked datasets using fill values do not - incur any additional overhead. See H5Pset_fill_value(). - -* Multiple hdf5 files can be "mounted" on one another to create a - larger virtual file. See H5Fmount(). - -* Object names can be removed or changed but objects are never - actually removed from the file yet. See H5Gunlink() and H5Gmove(). - -* Added a tuning mechanism for B-trees to insure that sequential - writes to chunked datasets use less overhead. See H5Pset_btree_ratios(). - -* Various optimizations and bug fixes. - - - -%%%%1.0.0 Beta%%%% Release Information for hdf5-1.0.0 Beta - -2. Changes from the Second Alpha 1.0.0 Release to the Beta 1.0.0 Release -========================================================================= - -* Strided hyperslab selections in dataspaces now working. - -* The compression API has been replaced with a more general filter - API. See doc/html/Filters.html for details. - -* Alpha-quality 2d ragged arrays are implemented as a layer built on - top of other hdf5 objects. The API and storage format will almost - certainly change. - -* More debugging support including API tracing. See Debugging.html. - -* C and Fortran style 8-bit fixed-length character string types are - supported with space or null padding or null termination and - translations between them. - -* Added function H5Fflush() to write all cached data immediately to - the file. - -* Datasets maintain a modification time which can be retrieved with - H5Gstat(). - -* The h5ls tool can display much more information, including all the - values of a dataset. - - - -%%%%1.0.0 Alpha 2%%%% Release Information for hdf5-1.0.0 Alpha 2 - -1. Changes from the First Alpha 1.0.0 Release to - the Second Alpha 1.0.0 Release -===================================================================== - -* Two of the packages have been renamed. The data space API has been - renamed from `H5P' to `H5S' and the property list (template) API has - been renamed from `H5C' to `H5P'. - -* The new attribute API `H5A' has been added. An attribute is a small - dataset which can be attached to some other object (for instance, a - 4x4 transformation matrix attached to a 3-dimensional dataset, or an - English abstract attached to a group). - -* The error handling API `H5E' has been completed. By default, when an - API function returns failure an error stack is displayed on the - standard error stream. The H5Eset_auto() controls the automatic - printing and H5E_BEGIN_TRY/H5E_END_TRY macros can temporarily - disable the automatic error printing. - -* Support for large files and datasets (>2GB) has been added. There - is an html document that describes how it works. Some of the types - for function arguments have changed to support this: all arguments - pertaining to sizes of memory objects are `size_t' and all arguments - pertaining to file sizes are `hsize_t'. - -* More data type conversions have been added although none of them are - fine tuned for performance. There are new converters from integer - to integer and float to float, but not between integers and floating - points. A bug has been fixed in the converter between compound - types. - -* The numbered types have been removed from the API: int8, uint8, - int16, uint16, int32, uint32, int64, uint64, float32, and float64. - Use standard C types instead. Similarly, the numbered types were - removed from the H5T_NATIVE_* architecture; use unnumbered types - which correspond to the standard C types like H5T_NATIVE_INT. - -* More debugging support was added. If tracing is enabled at - configuration time (the default) and the HDF5_TRACE environment - variable is set to a file descriptor then all API calls will emit - the function name, argument names and values, and return value on - that file number. There is an html document that describes this. - If appropriate debugging options are enabled at configuration time, - some packages will display performance information on stderr. - -* Data types can be stored in the file as independent objects and - multiple datasets can share a data type. - -* The raw data I/O stream has been implemented and the application can - control meta and raw data caches, so I/O performance should be - improved from the first alpha release. - -* Group and attribute query functions have been implemented so it is - now possible to find out the contents of a file with no prior - knowledge. - -* External raw data storage allows datasets to be written by other - applications or I/O libraries and described and accessed through - HDF5. - -* Hard and soft (symbolic) links are implemented which allow groups to - share objects. Dangling and recursive symbolic links are supported. - -* User-defined data compression is implemented although we may - generalize the interface to allow arbitrary user-defined filters - which can be used for compression, checksums, encryption, - performance monitoring, etc. The publicly-available `deflate' - method is predefined if the GNU libz.a can be found at configuration - time. - -* The configuration scripts have been modified to make it easier to - build debugging vs. production versions of the library. - -* The library automatically checks that the application was compiled - with the correct version of header files. - - - Parallel HDF5 Changes - -* Parallel support for fixed dimension datasets with contiguous or - chunked storages. Also, support unlimited dimension datasets which - must use chunk storage. No parallel support for compressed datasets. - -* Collective data transfer for H5Dread/H5Dwrite. Collective access - support for datasets with contiguous storage only, thus only fixed - dimension datasets for now. - -* H5Pset_mpi and H5Pget_mpi no longer have the access_mode - argument. It is taken over by the data-transfer property list - of H5Dread/H5Dwrite. - -* New functions H5Pset_xfer and H5Pget_xfer to handle the - specification of independent or collective data transfer_mode - in the dataset transfer properties list. The properties - list can be used to specify data transfer mode in the H5Dwrite - and H5Dread function calls. - -* Added parallel support for datasets with chunked storage layout. - When a dataset is extend in a PHDF5 file, all processes that open - the file must collectively call H5Dextend with identical new dimension - sizes. - - - LIST OF API FUNCTIONS - -The following functions are implemented. Errors are returned if an -attempt is made to use some feature which is not implemented and -printing the error stack will show `not implemented yet'. - -Library - H5check - check that lib version matches header version -
