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.

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.

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 -
