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. QAK - 2005/03/19 + + Tools + ----- + + Documentation + ------------- + + F90 API + ------- + - h5pget_driver_f was returning information that could not be + interpreted by a Fortran application program; fixed. EIP - 2005/04/10 + + C++ API + ------- + - Several member functions' prototype changed due to the + "int -> unsigned" change in the main library. They are: + H5::CompType::getMemberDataType(unsigned member_num) + H5::CompType::getMemberCompType(unsigned member_num) + H5::CompType::getMemberEnumType(unsigned member_num) + H5::CompType::getMemberIntType(unsigned member_num) + H5::CompType::getMemberFloatType(unsigned member_num) + H5::CompType::getMemberStrType(unsigned member_num) + BMR - 2005/07/27 + + + + + +Platforms Tested +================ + + AIX 5.1 (32 and 64-bit) xlc 6.0.0.6 + xlf 8.1.1.3 + xlC 6.0.0.6 + mpcc_r 6.0.0.6 + mpxlf_r 8.1.1.3 + xlc 5.0.2.5 + xlf 7.1.1.2 + xlC 5.0.2.5 + mpcc_r 5.0.2.5 + mpxlf_r 7.1.1.2 + AIX 5.2 (32/64 bit) xlc 6.0.0.8 + xlC 6.0.0.9 + xlf 8.1.1.7 + mpcc_r 6.0.0.8 + mpxlf_r 8.1.1.7 + AIX 5.2 (32/64 bit, LLNL frost) xlc 6.0.0.8 + xlC 6.0.0.8 + xlf 8.1.1.7 + mpcc_r 6.0.0.8 + mpxlf_r 8.1.1.7 + AIX 5.3 (32/64 bit) xlc 7.0.0.0 + xlC 7.0. + xlf 9.1.0.3 + Cray X1 water 3.0.35 Cray Standard C Version 5.4.0.7.4 + Cray Fortran 5.4.0.7.3 + Cray C++ 5.4.0.7.4 + FreeBSD 4.11 gcc 2.95.4 + g++ 2.95.4 + gcc 3.2.3, 3.3.6, 3.4.4, 4.0.0 + HP-UX B.11.00 HP C HP92453-01 A.11.01.20 + HP F90 v2.4 + HP ANSI C++ B3910B A.03.13 + HP-UX B.11.23 HP aC++/ANSI C B3910B A.06.00 + HP F90 v2.9 + HP aC++/ANSI C B3910B A.06.00 + IRIX64 6.5 (tesla -64) MIPSpro cc 7.4.2m + F90 MIPSpro 7.4.2m + C++ MIPSpro cc 7.4.2m + IRIX64 6.5 (64 & n32) MIPSpro cc 7.3.1.3m + F90 MIPSpro 7.3.1.3m (64 only) + C++ MIPSpro cc 7.3.1.3m + mpt 1.6 + Linux 2.4.20-28.7 gcc 2.96 + (eirene, verbena) gcc 3.3.2 + PGI compilers (pgcc, pgf90, pgCC) + version 5.2-1 + Absoft Fortran compiler v9.0 + Intel(R) C++ 32-bit Version 8.1 + Intel(R) Fortran 32-bit Version 8.1 + MPIch 1.2.6 + Linux 2.4.21-268-smp x86_64 gcc 3.3.1 (SuSE Linux, AMD) + (mir) PGI 5.2-1 C and F90 (with k3-32) + Intel(R) C++ 32-bit Version 8.1 + Intel(R) Fortran 32-bit Version 8.1 + Linux 2.4.21-sgi306rp21 Altix + SMP ia64 Intel(R) C++ Version 8.1 + (cobalt) Intel(R) Fortran Itanium(R) Version 8.1 + SGI MPI + OSF1 V5.1 (QSC) Compaq C V6.5-011 + HP Fortran V5.5A-3548 + Compaq C++ V6.5-036 + MPIX200_64_r13.4 + OSF1 V5.1 (PSC) Compaq C V6.5-303 + HP Fortran V5.5A-3548 + Compaq C++ V6.5-040 + SunOS 5.8 32,46 Sun WorkShop 6 update 2 C 5.3 + (Solaris 2.8) Sun WorkShop 6 update 2 Fortran 90 + Sun WorkShop 6 update 2 C++ 5.3 + SunOS 5.9 32,64 Sun C 5.6 2004/07/15 + (Solaris 2.9) Sun Fortran 95 8.0 2004/07/15 + Sun C++ 5.6 2004/07/15 + SunOS 5.10 Sun WorkShop 6 update 2 C 5.3 + Sun WorkShop 6 update 2 Fortran 95 6.2 + Sun WorkShop 6 update 2 C++ 5.3 + Patch 111685-13 + Xeon Linux 2.4.21-32.0.1.ELsmp-perfctr-lustre + (tungsten) Intel(R) C++ Version 9.0 + Intel(R) Fortran Compiler Version 9.0 + IA-64 Linux 2.4.21.SuSE_292.til1 ia64 + (NCSA tg-login) Intel(R) C++ Version 8.0 + Intel(R) Fortran Compiler Version 8.0 + mpich-gm-1.2.5..10-intel-r2 + Windows XP MSVC++.NET + MSVC++ 6.0 + Intel 8.1 C++ + MAC OS X Darwin 7.5 + gcc and g++ Apple Computer, Inc.

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. 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 HDF5-1.6.3 +- Documentation +- Platforms Tested +- Supported Configuration Features Summary +- Known Problems + + +New Features +============ + Source code distribution: + ------------------------- + + The High-Level (HL) C APIs were added to the source code distribution. + For HL documentation, see + http://hdf.ncsa.uiuc.edu/HDF5/hdf5_hl/doc/RM_hdf5hl.html. + + The HL library, libhdf5_hl.a(so), is built and installed by default. + Use --disable-hl configure flag to disable the HL library. + + Library: + -------- + - We recommend you to use SZIP v2.0 with this release. + For more information see + http://hdf.ncsa.uiuc.edu/doc_resource/SZIP/ + - The compound datatype has been enhanced with a new feature of size + adjustment. 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.

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.

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.

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.

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. QAK - 2003/11/07 + - Hoisted invariant 'if/else's out of inner datatype conversion loop for + integer and floating-point values, giving about a 20% speedup. + QAK - 2003/10/20 + + Tools + ----- + - Fixed h5redeploy which sometimes complain too many argument for the + test command.

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) |
