Release Information for hdf5-1.2.2 + +INTRODUCTION + +This document describes the differences between HDF5-1.2.1 and +HDF5-1.2.2, and contains information on the platforms where HDF5-1.2.2 +was tested and known problems in HDF5-1.2.2. + +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 + +- Features Added since HDF5-1.2.1 +- Bug Fixes since HDF5-1.2.1 +- Known Problems +- Platforms Tested + + +Features Added since HDF5-1.2.1 +=============================== + * Added internal free-lists to reduce memory required by the library and + H5garbage_collect API function. + * h5dump displays opaque and bitfield types. + * 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. + +Bug Fixes since HDF5-1.2.1 +========================== + * h5dump correctly displays compound datatypes, including simple and + nested compound types. + * h5dump correctly displays the committed copy of predefined types. + * Corrected an error in h5toh4 which did not convert the 32-bit + int from HDF5 to HDF4 correctly for the T3E platform. + * Corrected a floating point number conversion error for the + Cray J90 platform. The error did not convert the value 0.0 + correctly. + * 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 caused 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 without the same dimension being unlimited. + * Improved metadata hashing & caching algorithms to avoid + many hash flushes and also removed some redundant I/O when moving metadata + blocks in the file. + * The libhdf5.settings file shows the correct machine byte-sex. + * 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. + +Known Problems +============== + +o SunOS 5.6 with C WorkShop Compilers 4.2: hyperslab selections will + fail if library is compiled using optimization of any level. +o TFLOPS: dsets test fails if compiled with optimization turned on. +o J90: tools fail to dispay data for the datasets with a compound datatype. + +Platforms Tested +================ + + AIX 4.3.3 (IBM SP) 3.6.6 | binaries + mpicc using mpich 1.1.2 | are not + mpicc_r using IBM MPI-IO prototype | available + AIX 4.3.2.0 (IBM SP) xlc 5.0.1.0 + Cray J90 10.0.0.7 cc 6.3.0.2 + Cray T3E 2.0.5.29 cc 6.3.0.2 + mpt.1.3 + FreeBSD 4.0 gcc 2.95.2 + HP-UX B.10.20 HP C HP92453-01 A.10.32 + HP-UX B.11.00 HP92453-01 A.11.00.13 HP C Compiler + (static library only, h5toh4 tool is not available) + IRIX 6.5 MIPSpro cc 7.30 + IRIX64 6.5 (64 & n32) MIPSpro cc 7.3.1m + mpt.1.4 + + Linux 2.2.10 SMP gcc 2.95.1 + mpicc(gcc-2.95.1) + gcc (egcs-2.91.66) + mpicc (egcs-2.91.66) + Linux 2.2.16 (RedHat 6.2) gcc 2.95.2 + + OSF1 V4.0 DEC-V5.2-040 + SunOS 5.6 cc WorkShop Compilers 5.0 no optimization + SunOS 5.7 cc WorkShop Compilers 5.0 + SolarisX86 SunOS 5.5.1 gcc version 2.7.2 with --disable-hsizet + TFLOPS 3.2.1 pgcc Rel 3.1-3i + mpich-1.1.2 with local changes + Windows NT4.0 sp5 MSVC++ 6.0 + Windows 98 MSVC++ 6.0 + Windows 2000 MSVC++ 6.0 + + + +%%%%1.2.1%%%% Release Information for hdf5-1.2.1 + +II. Release Information for hdf5-1.2.1 + +Bug fixes since HDF5-1.2.0 +========================== + +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.

Changes Since Version 1.0.1 + --------------------------- + +1. Documentation + ------------- + +* More examples + +* Updated user guide, reference manual, and format specification. + +* Self-contained documentation for installations isolated from the + Internet. + +* HDF5 Tutorial was added to the documentation + +2. Configuration + ------------- + +* Better detection and support for MPI-IO. + +* Recognition of compilers with known code generation problems. + +* Support for various compilers on a single architecture (e.g., the + native compiler and the GNU compilers). + +* Ability to build from read-only media and with different compilers + and/or options concurrently. + +* Added a libhdf5.settings file which summarizes the configuration + information and is installed along with the library. + +* Builds a shared library on most systems that support it. + +* Support for Cray T3E, J90 and Windows/NT. + +3. Debugging + --------- + +* Improved control and redirection of debugging and tracing messages. + +4. Datatypes + --------- + +* Optimizations to compound datatype conversions and I/O operations. + +* Added nearly 100 optimized conversion functions for native datatypes + including support for non-aligned data. + +* Added support for bitfield, opaque, and enumeration types. + +* Added distinctions between signed and unsigned char types to the + list of predefined native hdf5 datatypes. + +* Added HDF5 type definitions for C9x types like int32_t. + +* Application-defined type conversion functions can handle non-packed + data. + +* Changed the H5Tunregister() function to use wildcards when matching + conversion functions. H5Tregister_hard() and H5Tregister_soft() + were combined into H5Tregister(). + +* Support for variable-length datatypes (arrays of varying length per + dataset element). Variable length strings currently supported only + as variable length arrays of 1-byte integers. + +5. Dataspaces + ---------- + +* New query functions for selections. + +* I/O operations bypass the stripmining loop and go directly to + storage for certain contiguous selections in the absense of type + conversions. In other cases the stripmining buffers are used more + effectively. + +* Reduced the number of I/O requests under certain circumstances, + improving performance on systems with high I/O latency. + +6. Persistent Pointers + ------------------- + +* Object (serial and parallel) and dataset region (serial only) + references are implemented. + +7. Parallel Support + ---------------- + +* Improved parallel I/O performance. + +* Supported new platforms: Cray T3E, Linux, DEC Cluster. + +* Use vendor supported version of MPIO on SGI O2K and Cray platforms. + +* Improved the algorithm that translates an HDF5 hyperslab selection + into an MPI type for better collective I/O performance. + +8.

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 + +V. 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 + +VI. 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 + +VII. 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 + H5open -
