New Features
|
|
|
|
============
|
|
|
|
o Configuration
|
|
|
|
================
|
|
|
|
* Added "unofficial support" for building with a C++ compiler (or at least
|
|
|
|
not failing badly when building with a C++ compiler). QAK - 2003/01/09
|
|
|
|
* Added "unofficial support" for AIX 64bits. See INSTALL for configure
|
|
|
|
details. AKC - 2002/08/29
|
|
|
|
* Added "--with-dmalloc" flag, to easily enable support for the 'dmalloc'
|
|
|
|
debugging malloc implementation. QAK - 2002/07/15
|
|
|
|
|
|
|
|
o Library
|
|
|
|
=========
|
|
|
|
o General
|
|
|
|
---------
|
|
|
|
* Allow scalar dataspaces to be used for parallel I/O. QAK - 2002/11/05
|
|
|
|
* Added environment variable "HDF5_DISABLE_VERSION_CHECK", which disables
|
|
|
|
the version checking between the header files and the library linked
|
|
|
|
into an application if set to '1'. This should be used with caution,
|
|
|
|
mis-matched headers and library binaries can cause _serious_ problems.
|
|
|
|
QAK - 2002/10/15
|
|
|
|
* Partially fixed space allocation inefficiencies in the file by
|
|
|
|
improving our algorithms for re-using freed space. QAK - 2002/08/27
|
|
|
|
* API tracing has been improved. Nested API calls don't screw up the
|
|
|
|
output format; function call and return event times can be logged;
|
|
|
|
total time spent in each function can be logged. The following
|
|
|
|
HDF5_DEBUG environment variable words affect tracing:
|
|
|
|
trace -- turn on/off basic tracing
|
|
|
|
ttimes -- turn on tracing and report event times and
|
|
|
|
time spent in each API function.
|
|
|
|
ttop -- turn on tracing but display only top-level
|
|
|
|
API calls.
|
|
|
|
|
|
|
|
o APIs
|
|
|
|
------
|
|
|
|
* Several missing fortran APIs have been added to the library:
|
|
|
|
|
|
|
|
h5get_libversion_f h5tget_member_index_f h5dget_storage_size_f
|
|
|
|
h5check_version_f h5tvlen_create_f h5dvlen_get_max_len_f
|
|
|
|
h5garbage_collect_f h5dwrite_vl_f
|
|
|
|
h5dont_atexit_f h5dread_vl_f
|
|
|
|
|
|
|
|
Functions h5dvlen_get_max_len_f, h5dwrite_vl_f, and h5dread_vl_f support
|
|
|
|
VL Length C APIs functionality for integer, real and string datatypes.
|
|
|
|
See HDF5 Reference Manual and HDF5 FORTRAN90 User's Notes for more
|
|
|
|
information and for the functions description.
|
|
|
|
|
|
|
|
o Parallel library
|
|
|
|
==================
|
|
|
|
* The MPI-posix virtual file driver makes gpfs_fcntl() hints to tell
|
|
|
|
the underlying GPFS file system to avoid prefetching byte range
|
|
|
|
tokens if USE_GPFS_HINTS is defined when this file is compiled.
|
|
|
|
This temporary solution is intended to be removed once the HDF5
|
|
|
|
API supports the necessary functionality that makes it possible
|
|
|
|
for this sort of thing do be done at a higher software layer.
|
|
|
|
RPM - 2002/12/03
|
|
|
|
* Added MPI-posix VFL driver. This VFL driver uses MPI functions to
|
|
|
|
coordinate actions, but performs I/O directly with POSIX sec(2)
|
|
|
|
(i.e. open/close/read/write/etc.) calls. This driver should _NOT_
|
|
|
|
be used to access files that are not on a parallel filesystem.
|
|
|
|
The following API functions were added:
|
|
|
|
herr_t H5Pset_fapl_mpiposix(hid_t fapl_id, MPI_Comm comm);
|
|
|
|
herr_t H5Pget_fapl_mpiposix(hid_t fapl_id, MPI_Comm *comm/*out*/);
|
|
|
|
QAK - 2002/07/15
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
o Support for new platforms and languages
|
|
|
|
=========================================
|
|
|
|
* C++ API now works on the Origin2000 (IRIX6.5.14.) BMR - 2002/11/14
|
|
|
|
|
|
|
|
|
|
|
|
o Misc.
|
|
|
|
=========================================
|
|
|
|
HDF5 1.4.5 works with Portland Group Compilers (pgcc, pgf90 and pgCC
|
|
|
|
version 4.0-2) on Linux 2.4
|
|
|
|
|
|
|
|
|
|
|
|
Bug Fixes since HDF5-1.4.4 Release
|
|
|
|
==================================
|
|
|
|
* H5Fopen without the H5F_ACC_CREAT flag should not succeed in creating
|
|
|
|
a new file with the 'core' VFL driver. QAK - 2003/01/24
|
|
|
|
* Corrected metadata caching bug in parallel I/O which could cause hangs
|
|
|
|
when chunked datasets were accessed with independent transfer mode.
|
|
|
|
QAK - 2003/01/23
|
|
|
|
* Allow opening objects with unknown object header messages.
|
|
|
|
QAK - 2003/01/21
|
|
|
|
* Added improved error assertion for nil VL strings. It return error
|
|
|
|
stack instead of a simple assertion. SLU - 2002/12/16
|
|
|
|
* Fixed h5dump bug(cannot dump data and datatype) for VL string.
|
|
|
|
SLU - 2002/11/18
|
|
|
|
* Fixed error condition where "none" selections were not being handled
|
|
|
|
correctly in serial & parallel. QAK - 2002/10/29
|
|
|
|
* Fixed problem where optimized hyperslab routines were incorrectly
|
|
|
|
invoked for parallel I/O operations in collective mode. QAK - 2002/07/22
|
|
|
|
* Fixed metadata corruption problem which could occur when many objects
|
|
|
|
are created in a file during parallel I/O. QAK - 2002/07/19
|
|
|
|
* Fixed minor problem with configuration when users specified /usr/include
|
|
|
|
and /usr/lib for the --with-* options that some compilers can't
|
|
|
|
handle. BW - 2003/01/23

Known Problems
|
|
|
|
==============
|
|
|
|
|
|
|
|
* On Linux 2.4 IA64, Fortran test fails for h5dwrite_vl_f
|
|
|
|
for integer and real base datatypes.
|
|
|
|
|
|
|
|
* When fortran library is built with Intel compilers, compilation
|
|
|
|
for fflush1.f90, fflush2.f90 and fortanlib_test.f90 will fail
|
|
|
|
complaining about EXEC function. Comment the call to EXEC subroutine
|
|
|
|
in each program, or get a patch for the HDF5 Fortran source code.
|
|
|
|
|
|
|
|
* Fortran external dataset test fails on Linux 2.4 with pgf90 compiler.
|
|
|
|
|
|
|
|
* On Windows, h5dump may abort printing if a VL string is longer than 4096
|
|
|
|
bytes due to a compiler problem. It'll be fixed in v1.6 release.
|
|
|
|
|
|
|
|
* Datasets or attributes which have a variable-length string datatype are
|
|
|
|
not printing correctly with h5dump and h5ls.
|
|
|
|
|
|
|
|
* When a dataset with the variable-length datatype is overwritten,
|
|
|
|
the library can develop memory leaks that cause the file to become
|
|
|
|
unnecessarily large. This is planned to be fixed in the next release.
|
|
|
|
|
|
|
|
* On the SV1, the h5ls test fails due to a difference between the
|
|
|
|
SV1 printf precision and the printf precision on other platforms.
|
|
|
|
|
|
|
|
* The h5dump tests may fail to match the expected output on some
|
|
|
|
platforms (e.g. SP2 parallel, Windows) where the error messages
|
|
|
|
directed to "stderr" do not appear in the "right order" with output
|
|
|
|
from stdout. This is not an error.
|
|
|
|
|
|
|
|
* The --enable-static-exec configure flag fails to compile for HP-UX
|
|
|
|
11.00 platforms.
|
|
|
|
|
|
|
|
* The executables are always dynamic on IRIX64 6.5(64 and n32) and
|
|
|
|
IRIX 6.5 even if they are configured with --enable-static-exec.
|
|
|
|
|
|
|
|
* IRIX 6.5 fails to compile if configured with --enable-static-exec.
|
|
|
|
|
|
|
|
* The executables are always dynamic on Solaris 2.7 ans 2.8(64 and n32)
|
|
|
|
even if they are configured with --enable-static-exec.
|
|
|
|
|
|
|
|
* The HDF5_MPI_OPT_TYPES optimization code in the parallel HDF5 will cause
|
|
|
|
a hang in some cases when chunked storage is used. This is now set to
|
|
|
|
be off by default. One may turn it on by setting the environment
|
|
|
|
variable HDF5_MPI_OPT_TYPES to a non-zero value such as 1.
|
|
|
|
|
|
|
|
* On OSF1 v5.1 and IA32 h5dumpgentst program that generates test files
|
|
|
|
for h5dump, gives segmentation fault.
|
|
|
|
|
|
|
|
* On Windows platforms, C and Fortran tests fail with the debug DLL version
|
|
|
|
of the Library if built from all_withf90.zip file.
|
|
|
|
|
|
|
|
* On Cray T3E (sn6606 2.0.6.08 unicosmk CRAY T3E) with Cray Standard C Version 6.6.0.1.3
|
|
|
|
compiler optimization causes errors in many HDF5 Library tests. Use -g -h zero flags
|
|
|
|
to build HDF5 Library.
|
|
|
|
|
|
|
|
* On Cray SV1 10.0.1. 0 datatype convertion test fails. Please check HDF FTP site
|
|
|
|
if patch is available. We will try to provide one in the nearest future.
|
|
|
|
|
|
|
|
* For configuration, building and testing with Intel and PGI compilers see
|
|
|
|
corresponding section in INSTALL file.

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

|
Performance Improvements
|
|
|
|
========================
|
|
|
|
This release of the HDF5 library has been extensively tuned to improve
|
|
|
|
performance, especially to improve parallel I/O performance.
|
|
|
|
Most of the specific information for particular performance improvements
|
|
|
|
is mentioned in the "New Features" and "Bug Fixes since HDF5-1.4.3" sections
|
|
|
|
of this document, but in general, the library should make fewer and larger
|
|
|
|
I/O requests when accessing a file. Additionally, improvements to the parallel
|
|
|
|
I/O portions of the library should have reduced the communications and barriers
|
|
|
|
used in various internal algorithms, improving the performance of the library.
|
|
|
|
However, with the extensive changes to some portions of the library that
|
|
|
|
were required for these improvements, some errors or unanticipated results may
|
|
|
|
have been introduced also. Please report any problems encountered to our
|
|
|
|
support team at hdfhelp@ncsa.uiuc.edu.
|
|
|
|
Hopefully these improvements will benefit all HDF5 applications, but if
|
|
|
|
there are particular I/O patterns that appear to be slower than necessary,
|
|
|
|
please send e-mail to hdfhelp@ncsa.uiuc.edu with a sample program showing the
|
|
|
|
problem behavior; we will look into the issue to see if it is possible to
|
|
|
|
address it.

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

New Features
|
|
|
|
============
|
|
|
|
o Configuration
|
|
|
|
================
|
|
|
|
* Can use just enable-threadsafe if the C compiler has built-in pthreads
|
|
|
|
support.
|
|
|
|
|
|
|
|
o Library
|
|
|
|
=========
|
|
|
|
o General
|
|
|
|
---------
|
|
|
|
* Added a new test to verify the information provided by the configure
|
|
|
|
command.
|
|
|
|
* Changed internal error handling macros to reduce code size of library by
|
|
|
|
about 10%.
|
|
|
|
|
|
|
|
o APIs
|
|
|
|
------
|
|
|
|
* Changed prototype for H5Awrite from:
|
|
|
|
H5Awrite(hid_t attr_id, hid_t type_id, void *buf)
|
|
|
|
to:
|
|
|
|
H5Awrite(hid_t attr_id, hid_t type_id, const void *buf)
|
|
|
|
* The H5Pset_fapl_split() accepts raw and meta file names similar to the
|
|
|
|
syntax of H5Pset_fapl_multi() in addition to what it used to accept.
|
|
|
|
|
|
|
|
C++ API:
|
|
|
|
* Added operator= to class PredType
|
|
|
|
* Add the overloaded member function Attribute::getName to return
|
|
|
|
the attribute name's length as in C API. Note that the current
|
|
|
|
Attribute::getName, that returns "string", is still available.
|
|
|
|
* Following the change in the C library, the corresponding C++ API
|
|
|
|
is changed from:
|
|
|
|
void Attribute::write( const DataType& mem_type, void *buf )
|
|
|
|
to:
|
|
|
|
void Attribute::write( const DataType& mem_type, const void *buf )
|
|
|
|
|
|
|
|
o Performance
|
|
|
|
-------------
|
|
|
|
* Added perform programs to test the HDF5 library performance. Programs
|
|
|
|
are installed in directory perform/.
|
|
|
|
* Improved performance of byte-swapping during data conversions.
|
|
|
|
* Improved performance of single, contiguous hyperslabs when reading or
|
|
|
|
writing.
|
|
|
|
* Added support to read/write portions of chunks directly, if they are
|
|
|
|
uncompressed and too large to cache. This should speed up I/O on chunked
|
|
|
|
datasets for a few more cases. -QAK, 1/31/02
|
|
|
|
|
|
|
|
o Parallel Library
|
|
|
|
==================
|
|
|
|
* Parallel C HDF5 now works on HP-UX platforms, Compaq clusters,
|
|
|
|
Linux clusters, Cplants (alpha-linux clusters).
|
|
|
|
|
|
|
|
o Tools
|
|
|
|
=======
|
|
|
|
* A helper script called ``h5cc'', which helps compilation of HDF5
|
|
|
|
programs, is now distributed with HDF5. See the reference manual
|
|
|
|
for information on how to use this feature.
|
|
|
|
* The H5Dumper can now dump comments associated with groups. -WCW 01-05-02
|
|
|
|
|
|
|
|
o Support for new platforms and languages
|
|
|
|
=========================================
|
|
|
|
* HDF5 C++ Library is supported on Windows platforms (shared and static)
|
|
|
|
* HDF5 F90 shared library is supported on Windows platforms.
|
|
|
|
* HDF5 C Library is supported on IA32 and IA64 platforms.
|
|

|
|
|
|
Bug Fixes since HDF5-1.4.2 Release
|
|
|
|
==================================
|
|
|
|
|
|
|
|
* Fixed a bug when reading chunked datasets where the edge of the dataset
|
|
|
|
would be incorrectly detected and generate an assertion failure.
|
|
|
|
* Fixed a bug where reading an entire dataset wasn't being handled
|
|
|
|
optimally when the dataset had unlimited dimensions. Dataset is read
|
|
|
|
in a single low-level I/O now, instead of being broken into separate
|
|
|
|
pieces internally.
|
|
|
|
* Fixed a bug where reading or writing chunked data which needed datatype
|
|
|
|
conversion could result in data values getting corrupted.
|
|
|
|
* Fixed a bug where appending a point selection to the current selection
|
|
|
|
would not actually append the point when there were no points defined
|
|
|
|
currently.
|
|
|
|
* Fixed a bug where 'or'ing a hyperslab with a 'none' selection would
|
|
|
|
fail. Now adds that hyperslab as the first hyperlab in the selection.
|
|
|
|
* Fixed a bug in the 'big' test where quota limits weren't being detected
|
|
|
|
properly if they caused close() to fail.
|
|
|
|
* Fixed a bug in internal B-tree code where a B-tree was not being copied
|
|
|
|
correctly.
|
|
|
|
* Fixed an off-by-one error in H5Sselect_valid when hyperslab selections
|
|
|
|
which would allow hyperslab selections which overlapped the edge of the
|
|
|
|
selection by one element as valid.
|
|
|
|
* Fixed the internal macros used to encode & decode file metadata, to avoid
|
|
|
|
an unaligned access warning on IA64 machines.
|
|
|
|
* Corrected behavior of H5Tinsert to not allow compound datatype fields to
|
|
|
|
be inserted past the end of the datatype.
|
|
|
|
* Retired the DPSS virtual file driver (--with-gridstorage configure
|
|
|
|
option).
|
|
|
|
* Fixed bug where variable-length datatypes for attributes was not working
|
|
|
|
correctly.
|
|
|
|
* Fixed bug where raw data re-allocated from the free-list would sometimes
|
|
|
|
overlap with the metadata accumulator and get corrupted. QAK - 1/23/02
|
|
|
|
* Fixed bug where a preempted chunk in the chunk data could still be
|
|
|
|
used by an internal pointer and cause an assertion failure or core
|
|
|
|
dump. QAK - 2/13/02
|
|
|
|
* Fixed bug where non-zero fill-value was not being read correctly from
|
|
|
|
certain chunked datasets when using an "all" or contiguous hyperslab
|
|
|
|
selection. QAK - 2/14/02
|

Known Problems
|
|
|
|
==============
|
|
|
|
|
|
|
|
* Datasets or attributes which have a variable-length string datatype are
|
|
|
|
not printing correctly with h5dump and h5ls.
|
|
|
|
|
|
|
|
* When a dataset with the variable-legth datatype is overwritten,
|
|
|
|
the library can develop memory leaks that cause the file to become
|
|
|
|
unnecessarily large. This is planned to be fixed in the next release.
|
|
|
|
|
|
|
|
* On the SV1, the h5ls test fails due to a difference between the
|
|
|
|
SV1 printf precision and the printf precision on other platforms.
|
|
|
|
|
|
|
|
|
|
|
|
* The h5dump tests may fail to match the expected output in some
|
|
|
|
platforms (e.g. SP2 parallel, Windows) where the error messages
|
|
|
|
directed to "stderr" do not appear in the "right order" with output
|
|
|
|
from stdout. This is not an error.
|
|
|
|
|
|
|
|
* The --enable-static-exec configure flag fails to compile for HP-UX
|
|
|
|
11.00 platforms.
|
|
|
|
|
|
|
|
* The executables are always dynamic on IRIX64 6.5(64 and n32) and
|
|
|
|
IRIX 6.5 even if they are configured with --enable-static-exec.
|
|
|
|
|
|
|
|
* IRIX 6.5 fails to compile if configured with --enable-static-exec.
|
|
|
|
|
|
|
|
* The HDF5_MPI_OPT_TYPES optimization code in the parallel HDF5 will cause
|
|
|
|
a hang in some cases when chunked storage is used. This is now set to
|
|
|
|
be off by default. One may turn it on by setting environment variable
|
|
|
|
HDF5_MPI_OPT_TYPES to a non-zero value such as 1.
|
|
|
|
|
|
|
|
* On IA64 systems one has to use -DIA64 compilation flag to compile
|
|
|
|
h4toh5 and h5toh4 utilites. After configuration step manually modify
|
|
|
|
Makefile in the tools/h4toh4 and tools/h5toh4 directories to add
|
|
|
|
-DIA64 to the compilation flags.
|
|
|
|
|
|
|
|
* On IA32 ansd IA64 systems, if you use a compiler other than GCC
|
|
|
|
(such as Intel's ecc compiler), you will need to modify the generated
|
|
|
|
"libtool" program after configuration is finished. On or around line 102
|
|
|
|
of the libtool file, there are lines which look like:
|
|
|
|
|
|
|
|
# How to pass a linker flag through the compiler.
|
|
|
|
wl=""
|
|
|
|
|
|
|
|
change the lines to this:
|
|
|
|
|
|
|
|
# How to pass a linker flag through the compiler.
|
|
|
|
wl="-Wl,"

New Features
|
|
|
|
============
|
|
|
|
|
|
|
|
* File sizes greater than 2GB are now supported on Linux systems with
|
|
|
|
version 2.4.x or higher kernels.
|
|
|
|
* Added a global string variable H5_lib_vers_info_g which holds the
|
|
|
|
HDF5 library version information. This can be used to identify
|
|
|
|
an hdf5 library or hdf5 application binary.
|
|
|
|
Also added a verification of the consistency between H5_lib_vers_info_g
|
|
|
|
and other version information in the source code.
|
|
|
|
* Parallel HDF5 now runs on the HP V2500 and HP N4000 machines.
|
|
|
|
* F90 API:
|
|
|
|
- Added aditional parameter "dims" to the h5dread_f/h5dwrite_f and
|
|
|
|
h5aread_f/h5awrite_f subroutines. This parameter is a 1-D array
|
|
|
|
of size 7 and contains the sizes of the data buffer dimensions.
|
|
|
|
This change enables portability between Windows and UNIX platforms.
|
|
|
|
In previous versions of the F90 APIs, the data buffer parameters of
|
|
|
|
the above functions were declared as assumed-shape arrays, which
|
|
|
|
were passed to the C functions by a descriptor. There is no
|
|
|
|
portable means, however, of passing descriptors from F90 to C,
|
|
|
|
causing portability problems between Windows and UNIX and among
|
|
|
|
UNIX platforms. With this change, the data buffers are assumed-
|
|
|
|
size arrays, which can be portably passed to the C functions.
|
|
|
|
* F90 static library is available on Windows platforms.
|
|
|
|
See INSTALL_Windows_withF90.txt for details.
|
|
|
|
* F90 APIs are available on HPUX 11.00 and 10.20 and IBM SP platforms.
|
|
|
|
* H5 <-> GIF convertor has been added. This is available under
|
|
|
|
tools/gifconv. The convertor supports the ability to create animated
|
|
|
|
gifs as well.
|
|
|
|
* Verified correct operation of library on Solaris 2.8 in both 64-bit and
|
|
|
|
32-bit compilation modes. See INSTALL document for instructions on
|
|
|
|
compiling the distribution with 64-bit support.
|
|
|
|
* Added support for the Metrowerks Code Warrior compiler for Windows.
|
|
|
|
* For H4->H5 converter utility, added a new option to choose not to convert
|
|
|
|
HDF4 specified attributes(reference number, class) into HDF5 attributes.
|
|
|
|
* Added support chunking and compression in SDS and image in H4->H5 converter.
|
|
|
|
Currently HDF5 only supports gzip compression, so by default an HDF4 file
|
|
|
|
with any other compression method will be converted into an HDF5 file in
|
|
|
|
gzip compression.
|
|
|
|
* correct the order or reading HDF4 image array in H4->H5 conversion.
|
|
|
|
* Added new parallel hdf5 tests in t_mpi. The new test checks if the
|
|
|
|
filesystem or the MPI-IO can really handle greater than 2GB files.
|
|
|
|
If it fails, it prints information message only without failing the
|
|
|
|
test.
|
|
|
|
* Added a parallel HDF5 example examples/ph5example.c to illustrate
|
|
|
|
the basic way of using parallel HDF5.
|
|
|
|
* Added a new public macro, H5_VERS_INFO, which is a string holding
|
|
|
|
the HDF5 library version information. This string is also compiled
|
|
|
|
into all HDF5 binary code which helps to identify the version information
|
|
|
|
of the binary code. One may use the Unix strings command on the binary
|
|
|
|
file and looks for the pattern "HDF5 library version".
|
|
|
|
* Added new checking in H5check_version() to verify the five HDF5 version
|
|
|
|
information macros (H5_VERS_MAJOR, H5_VERS_MINOR, H5_VERS_RELEASE,
|
|
|
|
H5_VERS_SUBRELEASE and H5_VERS_INFO) are consistent.

Bug Fixes since HDF5-1.4.1 Release
|
|
|
|
==================================
|
|
|
|
|
|
|
|
* Fixed bug with non-zero userblock sizes causing raw data to not
|
|
|
|
write correctly.
|
|
|
|
* Fixed problems with Pablo build and linking with non-standard MPI I/O.
|
|
|
|
* Fixed build on Linux systems with --enable-static-exec flag. It now
|
|
|
|
works correctly.
|
|
|
|
* IMPORTANT: Fixed file metadata corruption bug which could cause
|
|
|
|
metadata data loss in certain situations.
|
|
|
|
* The allocation by alignment (H5Pset_alignment) feature code somehow
|
|
|
|
got dropped in some 1.3.x version. Re-implemented it with "new and
|
|
|
|
improved" algorithm. It keeps track of "wasted" file-fragment in
|
|
|
|
the free-list too.
|
|
|
|
* Removed limitation that the data transfer buffer size needed to be
|
|
|
|
set for datasets whose dimensions were too large for the 'all'
|
|
|
|
selection code to handle. Any size dimensioned datasets should be
|
|
|
|
handled correctly now.
|
|
|
|
* Changed behavior of H5Tget_member_type to correctly emulate HDF5 v1.2.x
|
|
|
|
when --enable-hdf5v1_2 configure flag is enabled.
|
|
|
|
* Added --enable-linux-lfs flag to allow more control over whether to
|
|
|
|
enable or disable large file support on Linux.
|
|
|
|
* Fixed various bugs releated to SDS dimensional scale conversions in H4->H5
|
|
|
|
converter.
|
|
|
|
* Fixed a bug to correctly convert HDF4 objects with fill value into HDF5.
|
|
|
|
* Fixed a bug of H5pubconf.h causing repeated definitions if it is included
|
|
|
|
more than once. hdf5.h now includes H5public.h which includes
|
|
|
|
H5pubconf.h. Applications should #include hdf5.h which handles multiple
|
|
|
|
inclusion correctly.
|
|
|
|
* Fixed H5FDmpio.h to be C++ friendly by making Parallel HDF5 API's to be
|
|
|
|
external to C++.
|
|
|
|
* Fixed a bug in H5FD_mpio_flush() that might result in negative file seek
|
|
|
|
if both MPIO and Split-file drivers are used together.

=============
|
|
|
|
|
|
|
|
* The H5T_conv_t and H5T_cdata_t structures are now properly defined
|
|
|
|
in the H5Tregister entry in the "H5T" section of the "HDF5 Reference
|
|
|
|
Manual" and described in detail in section 12, "Data Conversions," in
|
|
|
|
the "Datatypes" chapter of the "HDF5 User's Guide."
|
|
|
|
* The new tools h52gif and gif2h5 have been added to the "Tools" section
|
|
|
|
of the Reference Manual.
|
|
|
|
* A "Freespace Management" section has been added to the "Performance"
|
|
|
|
chapter of the User's Guide.
|
|
|
|
* Several user-reported bugs have been fixed since Release 1.4.1.
|
|
|
|
* The "HDF5 Image and Palette Specification" (in the "HDF5 Application
|
|
|
|
Developer's Guide") has been heavily revised. Based on extensive user
|
|
|
|
feedback and input from visualization software developers, Version 1.2
|
|
|
|
of the image specification is substantially different from prior
|
|
|
|
versions.

Known Problems
|
|
|
|
==============
|
|
|
|
|
|
|
|
* When a dataset with the variable-legth datatype is overwritten,
|
|
|
|
the library can develop memory leaks that cause the file to become
|
|
|
|
unnecessarily large. This is planned to be fixed in the next release.
|
|
|
|
|
|
|
|
* On the SV1, the h5ls test fails due to a difference between the
|
|
|
|
SV1 printf precision and the printf precision on other platforms.
|
|
|
|
|
|
|
|
* The h5dump tests may fail to match the expected output in some
|
|
|
|
platforms (e.g. SP2 parallel, Windows) where the error messages
|
|
|
|
directed to "stderr" do not appear in the "right order" with output
|
|
|
|
from stdout. This is not an error.
|
|
|
|
|
|
|
|
* The --enable-static-exec configure flag fails to compile for HP-UX
|
|
|
|
11.00 platforms.
|
|
|
|
|
|
|
|
* The executables are always dynamic on IRIX64 6.5(64 and n32) and
|
|
|
|
IRIX 6.5 even if they are configured with --enable-static-exec.
|
|
|
|
|
|
|
|
* IRIX 6.5 fails to compile if configured with --enable-static-exec.
|
|
|
|
|
|
|
|
* For 24-bit image conversion from H4->H5, the current conversion is
|
|
|
|
not consistent with HDF5 image specification.
|
|
|
|
|
|
|
|
* In some cases, and SDS with an UNLIMITED dimension that has not
|
|
|
|
been written (current size = 0) is not converted correctly.
|
|
|
|
|
|
|
|
* After "make install" or "make install-doc" one may need to reload
|
|
|
|
the source from the tar file before doing another build.
|
|
|
|
|
|
|
|
* The HDF5_MPI_OPT_TYPES optimization code in the parallel HDF5 will cause
|
|
|
|
a hang in some cases when chunked storage is used. This is now set to
|
|
|
|
be off by default. One may turn it on by setting environment variable
|
|
|
|
HDF5_MPI_OPT_TYPES to a non-zero value such as 1.

New Features
|
|
|
|
============
|
|
|
|
|
|
|
|
* XML output option for h5dump utility.
|
|
|
|
|
|
|
|
A new option --xml to output data in XML format has been added. The
|
|
|
|
XML output contains a complete description of the file, marked up in
|
|
|
|
XML.
|
|
|
|
|
|
|
|
The XML conforms to the HDF5 Document Type Definition (DTD), which
|
|
|
|
is available at:
|
|
|
|
|
|
|
|
http://hdf.ncsa.uiuc.edu/DTDs/HDF5-File.dtd
|
|
|
|
|
|
|
|
The XML output is suitable for use with other tools, including the
|
|
|
|
Java Tools:

Bug Fixes since HDF5-1.4.0 Release
|
|
|
|
==================================
|
|
|
|
|
|
|
|
* h4toh5 utility: conversion of images is fixed
|
|
|
|
|
|
|
|
Earlier releases of the h4toh5 utility produced images that did not
|
|
|
|
correctly conform to the HDF5 Image and Palette Specification.
|
|
|
|
|
|
|
|
http://hdf.ncsa.uiuc.edu/HDF5/doc/ImageSpec.html
|
|
|
|
|
|
|
|
Several required HDF5 attributes are omitted, and the dataspace
|
|
|
|
is reversed (i.e., the ht. and width of the image dataset is
|
|
|
|
incorrectly described.) For more information, please see:
|
|
|
|
|
|
|
|
http://hdf.ncsa.uiuc.edu/HDF5/H5Image/ImageDetails.htm
|
|
|
|
|
|
|
|
* Fixed bug with contiguous hyperslabs not being detected, causing
|
|
|
|
slower I/O than necessary.
|
|
|
|
* Fixed bug where non-aligned hyperslab I/O on chunked datasets was
|
|
|
|
causing errors during I/O
|
|
|
|
* The RCSID string in H5public.h was causing the C++ compiling problem
|
|
|
|
because when it was included multiple times, C++ did not like
|
|
|
|
multiple definitions of the same static variable. All occurance of
|
|
|
|
RCSID definition are removed since we have not used it consistently
|
|
|
|
before.

New Features
|
|
|
|
============
|
|
|
|
* The Virtual File Layer, VFL, was added to replace the old file
|
|
|
|
drivers. It also provides an API for user defined file drivers.
|
|
|
|
* New features added to snapshots. Use 'snapshot help' to see a
|
|
|
|
complete list of features.
|
|
|
|
* Improved configure to detect if MPIO routines are available when
|
|
|
|
parallel mode is requested.
|
|
|
|
* Added Thread-Safe support. Phase I implemented. See:
|
|
|
|
|
|
|
|
http://hdf.ncsa.uiuc.edu/HDF5/papers/mthdf/MTHDFpaper.htm
|
|
|
|
|
|
|
|
for more details.
|
|
|
|
* Added data sieve buffering to raw data I/O path. This is enabled
|
|
|
|
for all VFL drivers except the mpio & core drivers. Setting the
|
|
|
|
sieve buffer size is controlled with the new API function,
|
|
|
|
H5Pset_sieve_buf_size(), and retrieved with H5Pget_sieve_buf_size().
|
|
|
|
* Added new Virtual File Driver, Stream VFD, to send/receive entire
|
|
|
|
HDF5 files via socket connections.
|
|
|
|
* As parts of VFL, HDF-GASS and HDF-SRB are also added to this
|
|
|
|
release. To find out details, please read INSTALL_VFL file.
|
|
|
|
* Increased maximum number of dimensions for a dataset (H5S_MAX_RANK)
|
|
|
|
from 31 to 32 to align with HDF4 & netCDF.
|
|
|
|
* Added 'query' function to VFL drivers. Also added 'type' parameter to
|
|
|
|
VFL 'read' & 'write' calls, so they are aware of the type of data
|
|
|
|
being accessed in the file. Updated the VFL document also.
|
|
|
|
* A new h4toh5 utility, to convert HDF4 files to analogous HDF5 files.
|
|
|
|
* Added a new array datatype to the datatypes which can be created.
|
|
|
|
Removed "array fields" from compound datatypes (use an array datatype
|
|
|
|
instead).
|
|
|
|
* Parallel HDF5 works correctly with mpich-1.2.1 on Solaris, SGI, Linux.
|
|
|
|
* You can now install the HDF5 documentation using the
|
|
|
|
``make install-doc'' command. The documentation is installed in the
|
|
|
|
$(prefix)/doc directory where $(prefix) is the prefix specified by
|
|
|
|
the (optional) ``--prefix'' flag during configuration.
|
|
|
|
* HDF5 can operate correctly in the OpenMP environment in a limited way.
|
|
|
|
Check doc/html/TechNotes/openmp-hdf5.html for details.

h4toh5 Utility
|
|
|
|
==============
|
|
|
|
The h4toh5 utility is a new utility that converts an HDF4 file to an
|
|
|
|
HDF5 file. For details, see the document, "Mapping HDF4 Objects to
|
|
|
|
HDF5 Objects":
|
|
|
|
http://hdf.ncsa.uiuc.edu/HDF5/papers/H4-H5MappingGuidelines.pdf
|
|
|
|
|
|
|
|
Known Bugs:
|
|
|
|
|
|
|
|
The h4toh5 utility produces images that do not correctly conform
|
|
|
|
to the HDF5 Image and Palette Specification.
|
|
|
|
|
|
|
|
http://hdf.ncsa.uiuc.edu/HDF5/doc/ImageSpec.html
|
|
|
|
|
|
|
|
Several required HDF5 attributes are omitted, and the dataspace
|
|
|
|
is reversed (i.e., the ht. and width of the image dataset is
|
|
|
|
incorrectly described.) For more information, please see:
|
|
|
|
|
|
|
|
http://hdf.ncsa.uiuc.edu/HDF5/H5Image/ImageDetails.html
|
|
|
|
|
|
|
|
This bug has been fixed for the snapshot of hdf5 1.4 release. March 12th,2001
|
|
|
|
|
|
|
|
Known Limitations of the h4toh5 release
|
|
|
|
---------------------------------------------
|
|
|
|
|
|
|
|
1. Error handlings
|
|
|
|
|
|
|
|
h4toh5 utility will print out an error message when an error occurs.
|
|
|
|
|
|
|
|
2. String Datatype
|
|
|
|
|
|
|
|
HDF4 has no 'string' type. String valued data are usually defined as
|
|
|
|
an array of 'char' in HDF4. The h4toh5 utility will generally map
|
|
|
|
these to HDF5 'String' types rather than array of char, with the
|
|
|
|
following additional rules:
|
|
|
|
|
|
|
|
* For the data of an HDF4 SDS, image, and palette, if the data is
|
|
|
|
declared 'DFNT_CHAR8' it will be assumed to be integer and will
|
|
|
|
be an H5T_INTEGER type.
|
|
|
|
* For attributes of any HDF4 object, data of type 'DFNT_CHAR8'
|
|
|
|
will be converted to an HDF5 'H5T_STRING' type.
|
|
|
|
* For an HDF4 Vdata, it is difficult to determine whether data
|
|
|
|
of type 'DFNT_CHAR8' is intended to be bytes or characters. The
|
|
|
|
h4toh5 utility will consider them to be C characters, and will
|
|
|
|
convert them to an HDF5 'H5T_STRING' type.
|
|
|
|
|
|
|
|
|
|
|
|
3. Compression, Chunking and External Storage
|
|
|
|
|
|
|
|
Chunking is supported, but compression and external storage is not.
|
|
|
|
|
|
|
|
An HDF4 object that uses chunking will be converted to an HDF5 file
|
|
|
|
with analogous chunked storage.
|
|
|
|
|
|
|
|
An HDF4 object that uses compression will be converted to an
|
|
|
|
uncompressed HDF5 object.
|
|
|
|
|
|
|
|
An HDF4 object that uses external storage will be converted to an
|
|
|
|
HDF5 object without external storage.
|
|
|
|
|
|
|
|
4. Memory Use
|
|
|
|
|
|
|
|
This version of the h4toh5 utility copies data from HDF4 objects
|
|
|
|
in a single read followed by a single write to the HDF5 object. For
|
|
|
|
large objects, this requires a very large amount of memory, which may
|
|
|
|
be extremely slow or fail on some platforms.
|
|
|
|
|
|
|
|
Note that a dataset that has only been partly written will
|
|
|
|
be read completely, including uninitialized data, and all the
|
|
|
|
data will be written to the HDF5 object.
|
|
|
|
|
|
|
|
5. Platforms
|
|
|
|
|
|
|
|
The h4toh5 utility requires HDF5-1.4.0 and HDF4r1.4
|
|
|
|
|
|
|
|
h4toh5 utility has been tested on all platforms listed below (see
|
|
|
|
section "Platforms Tested") except TFLOPS.
|
|
|
|
|
|
|
|
|
|
|
|
F90 Support
|
|
|
|
===========
|
|
|
|
This is the first release of the HDF5 Library with fully integrated
|
|
|
|
F90 API support. The Fortran Library is created when the
|
|
|
|
--enable-fortran flag is specified during configuration.
|
|
|
|
|
|
|
|
Not all F90 subroutines are implemented. Please refer to the HDF5
|
|
|
|
Reference Manual for more details.
|
|
|
|
|
|
|
|
F90 APIs are available for the Solaris 2.6 and 2.7, Linux, DEC UNIX,
|
|
|
|
T3E, SV1 and O2K (64 bit option only) platforms. The Parallel version of
|
|
|
|
the HDF5 F90 Library is supported on the O2K and T3E platforms.
|
|
|
|
|
|
|
|
Changes since the last prototype release (July 2000)
|
|
|
|
----------------------------------------------------
|
|
|
|
* h5open_f and h5close_f must be called instead of h5init_types and
|
|
|
|
h5close_types.
|
|
|
|
|
|
|
|
* The following subroutines are no longer available:
|
|
|
|
|
|
|
|
h5pset_xfer_f
|
|
|
|
h5pget_xfer_f
|
|
|
|
h5pset_mpi_f
|
|
|
|
h5pget_mpi_f
|
|
|
|
h5pset_stdio_f
|
|
|
|
h5pget_stdio_f
|
|
|
|
h5pset_sec2_f
|
|
|
|
h5pget_sec2_f
|
|
|
|
h5pset_core_f
|
|
|
|
h5pget_core_f
|
|
|
|
h5pset_family_f
|
|
|
|
h5pget_family_f
|
|
|
|
|
|
|
|
* The following functions have been added:
|
|
|
|
|
|
|
|
h5pset_fapl_mpio_f
|
|
|
|
h5pget_fapl_mpio_f
|
|
|
|
h5pset_dxpl_mpio_f
|
|
|
|
h5pget_dxpl_mpio_f
|
|
|
|
|
|
|
|
* In the previous HDF5 F90 releases, the implementation of object
|
|
|
|
references and dataset region references was not portable. This
|
|
|
|
release introduces a portable implementation, but it also introduces
|
|
|
|
changes to the read/write APIs that handle references. If object or
|
|
|
|
dataset region references are written or read to/from an HDF5 file,
|
|
|
|
h5dwrite_f and h5dread_f must use the extra parameter, n, for the
|
|
|
|
buffer size:
|
|
|
|
|
|
|
|
h5dwrite(read)_f(dset_id, mem_type_id, buf, n, hdferr, &
|
|
|
|
^^^
|
|
|
|
mem_space_id, file_space_id, xfer_prp)
|
|
|
|
|
|
|
|
For other datatypes the APIs were not changed.
|
|
|
|
|
|
|
|
|
|
|
|
C++ Support
|
|
|
|
===========
|
|
|
|
This is the first release of the HDF5 Library with fully integrated
|
|
|
|
C++ API support. The HDF5 C++ library is built when the --enable-cxx
|
|
|
|
flag is specified during configuration.
|
|
|
|
|
|
|
|
Check the HDF5 Reference Manual for available C++ documentation.
|
|
|
|
|
|
|
|
C++ APIs are available for Solaris 2.6 and 2.7, Linux, and FreeBSD.
|
|
|
|
|
|

|
Pablo Support
|
|
|
|
=============
|
|
|
|
This version does not allow proper building of the Pablo-instrumented
|
|
|
|
version of the library. A version supporting the pablo build is
|
|
|
|
available on the Pablo Website at
|
|
|
|

Bug Fixes since HDF5-1.2.0
|
|
|
|
==========================
|
|
|
|
|
|
|
|
Library
|
|
|
|
-------
|
|
|
|
* The function H5Pset_mpi is renamed as H5Pset_fapl_mpio.
|
|
|
|
* Corrected a floating point number conversion error for the Cray J90
|
|
|
|
platform. The error did not convert the value 0.0 correctly.
|
|
|
|
* Error was fixed which was not allowing dataset region references to
|
|
|
|
have their regions retrieved correctly.
|
|
|
|
* Corrected a bug that caused non-parallel file drivers to fail in
|
|
|
|
the parallel version.
|
|
|
|
* Added internal free-lists to reduce memory required by the library
|
|
|
|
and H5garbage_collect API function
|
|
|
|
* Fixed error in H5Giterate which was not updating the "index"
|
|
|
|
parameter correctly.
|
|
|
|
* Fixed error in hyperslab iteration which was not walking through the
|
|
|
|
correct sequence of array elements if hyperslabs were staggered in a
|
|
|
|
certain pattern
|
|
|
|
* Fixed several other problems in hyperslab iteration code.
|
|
|
|
* Fixed another H5Giterate bug which was causes groups with large
|
|
|
|
numbers of objects in them to misbehave when the callback function
|
|
|
|
returned non-zero values.
|
|
|
|
* Changed return type of H5Aiterate and H5A_operator_t typedef to be
|
|
|
|
herr_t, to align them with the dataset and group iterator functions.
|
|
|
|
* Changed H5Screate_simple and H5Sset_extent_simple to not allow
|
|
|
|
dimensions of size 0 with out the same dimension being unlimited.
|
|
|
|
* QAK - 4/19/00 - Improved metadata hashing & caching algorithms to
|
|
|
|
avoid many hash flushes and also remove some redundant I/O when
|
|
|
|
moving metadata blocks in the file.
|
|
|
|
* The "struct(opt)" type conversion function which gets invoked for
|
|
|
|
certain compound datatype conversions was fixed for nested compound
|
|
|
|
types. This required a small change in the datatype conversion
|
|
|
|
function API.
|
|
|
|
* Re-wrote lots of the hyperslab code to speed it up quite a bit.
|
|
|
|
* Added bounded garbage collection for the free lists when they run
|
|
|
|
out of memory and also added H5set_free_list_limits API call to
|
|
|
|
allow users to put an upper limit on the amount of memory used for
|
|
|
|
free lists.
|
|
|
|
* Checked for non-existent or deleted objects when dereferencing one
|
|
|
|
with object or region references and disallow dereference.
|
|
|
|
* "Time" datatypes (H5T_UNIX_D*) were not being stored and retrieved
|
|
|
|
from object headers correctly, fixed now.
|
|
|
|
* Fixed H5Dread or H5Dwrite calls with H5FD_MPIO_COLLECTIVE requests
|
|
|
|
that may hang because not all processes are transfer the same amount
|
|
|
|
of data. (A.K.A. prematured collective return when zero amount data
|
|
|
|
requested.) Collective calls that may cause hanging is done via the
|
|
|
|
corresponding MPI-IO independent calls.
|
|
|
|
* If configure with --enable-debug=all, couple functions would issue
|
|
|
|
warning messages to "stderr" that the operation is expensive time-wise.
|
|
|
|
This messed up applications (like testings) that did not expect the
|
|
|
|
extra output. It is changed so that the warning will be printed only
|
|
|
|
if the corresponding Debug key is set.
|
|
|
|
|
|
|
|
Configuration
|
|
|
|
-------------
|
|
|
|
* The hdf5.h include file was fixed to allow the HDF5 Library to be
|
|
|
|
compiled with other libraries/applications that use GNU autoconf.
|
|
|
|
* Configuration for parallel HDF5 was improved. Configure now attempts
|
|
|
|
to link with libmpi.a and/or libmpio.a as the MPI libraries by
|
|
|
|
default. It also uses "mpirun" to launch MPI tests by default. It
|
|
|
|
tests to link MPIO routines during the configuration stage, rather
|
|
|
|
than failing later as before. One can just do "./configure
|
|
|
|
--enable-parallel" if the MPI library is in the system library.
|
|
|
|
* Added support for pthread library and thread-safe option.
|
|
|
|
* The libhdf5.settings file shows the correct machine byte-sex.
|
|
|
|
* Added option "--enable-stream-vfd" to configure w/o the Stream VFD.
|
|
|
|
For Solaris, added -lsocket to the LIBS list of libraries.
|
|
|
|
|
|
|
|
Tools
|
|
|
|
-----
|
|
|
|
* h5dump now accepts both short and long command-line parameters:
|
|
|
|
-h, --help Print a usage message and exit
|
|
|
|
-B, --bootblock Print the content of the boot block
|
|
|
|
-H, --header Print the header only; no data is displayed
|
|
|
|
-i, --object-ids Print the object ids
|
|
|
|
-V, --version Print version number and exit
|
|
|
|
-a P, --attribute=P Print the specified attribute
|
|
|
|
-d P, --dataset=P Print the specified dataset
|
|
|
|
-g P, --group=P Print the specified group and all members
|
|
|
|
-l P, --soft-link=P Print the value(s) of the specified soft link
|
|
|
|
-o F, --output=F Output raw data into file F
|
|
|
|
-t T, --datatype=T Print the specified named data type
|
|
|
|
-w #, --width=# Set the number of columns
|
|
|
|
|
|
|
|
P - is the full path from the root group to the object.
|
|
|
|
T - is the name of the data type.
|
|
|
|
F - is a filename.
|
|
|
|
# - is an integer greater than 1.
|
|
|
|
* A change from the old way command line parameters were interpreted
|
|
|
|
is that multiple attributes, datasets, groups, soft-links, and
|
|
|
|
object-ids cannot be specified with just one flag but you have to
|
|
|
|
use a flag with each object. I.e., instead of doing this:
|
|
|
|
|
|
|
|
h5dump -a /attr1 /attr2 foo.h5
|
|
|
|
|
|
|
|
do this:
|
|
|
|
|
|
|
|
h5dump -a /attr1 -a /attr2 foo.h5
|
|
|
|
|
|
|
|
The cases are similar for the other object types.
|
|
|
|
* h5dump correctly displays compound datatypes.
|
|
|
|
* Corrected an error in h5toh4 which did not convert the 32bits
|
|
|
|
int from HDF5 to HDF4 correctly for the T3E platform.
|
|
|
|
* h5dump correctly displays the committed copy of predefined types
|
|
|
|
correctly.
|
|
|
|
* Added an option, -V, to show the version information of h5dump.
|
|
|
|
* Fixed a core dumping bug of h5toh4 when executed on platforms like
|
|
|
|
TFLOPS.
|
|
|
|
* The test script for h5toh4 used to not able to detect the hdp
|
|
|
|
dumper command was not valid. It now detects and reports the
|
|
|
|
failure of hdp execution.
|
|
|
|
* Merged the tools with the 1.2.2 branch. Required adding new
|
|
|
|
macros, VERSION12 and VERSION13, used in conditional compilation.
|
|
|
|
Updated the Windows project files for the tools.
|
|
|
|
* h5dump displays opaque and bitfield data correctly.
|
|
|
|
* h5dump and h5ls can browse files created with the Stream VFD
|
|
|
|
(eg. "h5ls <hostname>:<port>").
|
|
|
|
* h5dump has a new feature "-o <filename>" which outputs the raw data
|
|
|
|
of the dataset into ascii text file <filename>.
|
|
|
|
* h5toh4 used to converts hdf5 strings type to hdf4 DFNT_INT8 type.
|
|
|
|
Corrected to produce hdf4 DFNT_CHAR type instead.
|
|

Bug Fixes since HDF5-1.4.0-beta2
|
|
|
|
================================
|
|
|
|
* Fixed a bug in the conversion from a little endian double to a big
|
|
|
|
endian float in some special cases.
|
|
|
|
* Corrected configuration error which was not including compression
|
|
|
|
support correctly.
|
|
|
|
* Cleaned up lots of warnings.
|
|
|
|
* Changed a few h5dump command line switches and added long versions of
|
|
|
|
the switches.
|
|
|
|
* Changed parameters for H5Tconvert, H5Pset_bufer and H5Pget_buffer from
|
|
|
|
size_t to hsize_t
|
|
|
|
* Fixed fairly obscure bug in hyperslab I/O which could (in rare cases)
|
|
|
|
not copy all the data during a transfer.
|
|
|
|
* Removed ragged array code from library.
|
|
|
|
* F90 library and module files are installed properly now on all supported
|
|
|
|
platforms.

|
Bug Fixes since HDF5-1.4.0 Release
|
|
|
|
==================================
|
|
|
|
|
|
|
|
* Fixed bug with contiguous hyperslabs not being detected, causing
|
|
|
|
slower I/O than necessary.
|
|
|
|
* Fixed bug where non-aligned hyperslab I/O on chunked datasets was
|
|
|
|
causing errors during I/O
|
|
|
|
* Implemented XML support in h5dump.

Documentation
|
|
|
|
=============
|
|
|
|
* A new document summarizing the changes in the library leading up to
|
|
|
|
the current release has been added:
|
|
|
|
HDF5 Software Changes from Release to Release
|
|
|
|
This document is in the Application Developer's Guide and is of
|
|
|
|
particular interest to developers who must keep an application
|
|
|
|
synchronized with the library.
|
|
|
|
* The documentation for the Fortran90 and C++ APIs is linked to the
|
|
|
|
opening page of the Reference Manual. Fortran90 functions are
|
|
|
|
individually referenced from the corresponding C functions through-
|
|
|
|
out the Reference Manual.
|
|
|
|
* User's Guide and Reference Manual were updated to reflect changed
|
|
|
|
function syntax and to fix reported bugs.
|
|
|
|
* Functions that are new at this release were added to the Reference
|
|
|
|
Manual.
|
|
|
|
* Functions that have been removed from the library were removed from
|
|
|
|
the User's Guide and the Reference Manual.
|
|
|
|
* PostScript and PDF versions of the Release 1.4 document set are
|
|
|
|
not available at the time of Release 1.4.0.

Known Problems
|
|
|
|
==============
|
|
|
|
* The stream-vfd test uses ip port 10007 for testing. If another
|
|
|
|
application is already using that port address, the test will hang
|
|
|
|
indefinitely and has to be terminated by the kill command. To try the
|
|
|
|
test again, change the port address in test/stream_test.c to one not
|
|
|
|
being used in the host.
|
|
|
|
|
|
|
|
* The --enable-static-exec configure flag fails to compile for Solaris
|
|
|
|
platforms. This is due to the fact that not all of the system
|
|
|
|
libraries on Solaris are available in a static format.
|
|
|
|
|
|
|
|
The --enable-static-exec configure flag also fails to correctly compile
|
|
|
|
on Linux platforms using the gcc-2.95.2 compiler.
|
|
|
|
|
|
|
|
The --enable-static-exec configure flag also fails to correctly compile
|
|
|
|
on IBM SP2 platform for the serial mode. The parallel mode works fine
|
|
|
|
with this option.
|
|
|
|
|
|
|
|
The compilation fails if configured with --enable-static-exec on IRIX 6.5.
|
|
|
|
|
|
|
|
The executable files in hdf5/bin are dynamic-linked for IRIX64 6.5(64 and
|
|
|
|
n32 modes) and IRIX 6.5, even though they are compiled with static library.
|
|
|
|
|
|
|
|
It is suggested that you don't use this option on these platforms
|
|
|
|
during configuration.
|
|
|
|
|
|
|
|
* testhdf5 got bus error with configuration options --prefix and --with-hdf4
|
|
|
|
on IRIX 6.5.
|
|
|
|
|
|
|
|
* With the gcc 2.95.2 compiler, HDF 5 uses the `-ansi' flag during
|
|
|
|
compilation. The ANSI version of the compiler complains about not being
|
|
|
|
able to handle the `long long' datatype with the warning:
|
|
|
|
|
|
|
|
warning: ANSI C does not support `long long'
|
|
|
|
|
|
|
|
This warning is innocuous and can be safely ignored.
|
|
|
|
|
|
|
|
* SunOS 5.6 with C WorkShop Compilers 4.2: Hyperslab selections will
|
|
|
|
fail if library is compiled using optimization of any level.
|
|
|
|
|
|
|
|
* When building hdf5 tools and applications on windows platform, a linking
|
|
|
|
warning: defaultlib "LIBC" conflicts with use of other libs will appear
|
|
|
|
on debug version when running VC++6.0. This warning doesn't affect building
|
|
|
|
and testing hdf5 applications. We will continue investigating this.
|
|
|
|
|
|
|
|
* h5toh4 converter fails two cases(tstr.h5 and tmany.h5) for release dll
|
|
|
|
version on windows 2000 and NT. The reason is possibly due to Windows NT
|
|
|
|
DLL convention on freeing memory. It seems that memory cannot be freed
|
|
|
|
across library or DLL. It is still under investigation.
|
|
|
|
|
|
|
|
* HDF-GASS testings and testhdf5 in the test directory will get bus error if
|
|
|
|
the configured with --with-gass.
|
|
|
|
|
|
|
|
* HDF-SRB testing got segmentation error on Solaris 2.7.
|
|
|
|
|
|
|
|
* The Stream VFD was not tested yet under Windows.
|
|
|
|
It is not supported in the TFLOPS machine.
|
|
|
|
|
|
|
|
* Shared library option is broken for IBM SP and some Origin 2000 platforms.
|
|
|
|
One needs to run ./configure with '--disable-shared --enable-static'.
|
|
|
|
|
|
|
|
* The ./dsets tests failed in the TFLOPS machine if the test program,
|
|
|
|
dsets.c, is compiled with the -O option. The hdf5 library still works
|
|
|
|
correctly with the -O option. The test program works fine if it is
|
|
|
|
compiled with -O1 or -O0. Only -O (same as -O2) causes the test
|
|
|
|
program to fail.
|
|
|
|
|
|
|
|
* Certain platforms give false negatives when testing h5ls:
|
|
|
|
- Solaris x86 2.5.1, Cray T3E and Cray J90 give errors during testing
|
|
|
|
when displaying object references in certain files. These are benign
|
|
|
|
differences due to the difference in sizes of the objects created on
|
|
|
|
those platforms. h5ls appears to be dumping object references
|
|
|
|
correctly.
|
|
|
|
- Cray J90 give errors during testing when displaying
|
|
|
|
some floating-point values. These are benign differences due to the
|
|
|
|
different precision in the values displayed and h5ls appears to be
|
|
|
|
dumping floating-point numbers correctly.
|
|
|
|
|
|
|
|
* Before building HDF5 F90 Library from source on Crays (T3E and SV1)
|
|
|
|
replace H5Aff.f90, H5Dff.f90 and H5Pff.f90 files in the fortran/src
|
|
|
|
subdirectory in the top level directory with the Cray-specific files from
|
|
|
|
the ftp://ftp.ncsa.uiuc.edu/HDF/HDF5/hdf5-1.4.0/src/crayf90/ directory.
|
|
|
|
|
|
|
|
* The h4toh5 utility produces images that do not correctly conform
|
|
|
|
to the HDF5 Image and Palette Specification.

|
|

|
|
|
|
|
|
|
Several required HDF5 attributes are omitted, and the dataspace
|
|
|
|
is reversed (i.e., the ht. and width of the image dataset is
|

|
incorrectly described.) For more information, please see:

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.

6. 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. Configure now attempts to
|
|
|
|
link with libmpi.a and/or libmpio.a as the MPI libraries by default.
|
|
|
|
It also uses "mpirun" to launch MPI tests by default. It tests to
|
|
|
|
link MPIO routines during the configuration stage, rather than failing
|
|
|
|
later as before. One can just do "./configure --enable-parallel"
|
|
|
|
if the MPI library is in the system library.

|
|
|
|
2000-04-12 02:28:31 +08:00
|
|
|
* Error was fixed which was not allowing dataset region references to have
|
|
|
|
their regions retrieved correctly.
|
|
|
|
* Added internal free-lists to reduce memory required by the library and
|
|
|
|
H5garbage_collect API function
|
|
|
|
* Fixed error in H5Giterate which was not updating the "index" parameter
|
|
|
|
correctly.
|
|
|
|
* Fixed error in hyperslab iteration which was not walking through the
|
|
|
|
correct sequence of array elements if hyperslabs were staggered in a
|
|
|
|
certain pattern
|
|
|
|
* Fixed several other problems in hyperslab iteration code.

|
|
|
* Added additional tests for group and attribute iteration.
|
|
|
|
* Added additional test for staggered hyperslab iteration.
|
|
|
|
* Added additional test for random 5-D hyperslab selection.

|
* Added an option, -V, to show the version information of h5dump.
|
|
|
|
* Fixed a core dumping bug of h5toh4 when executed on platforms like
|
|
|
|
TFLOPS.
|
|
|
|
* The test script for h5toh4 used to not able to detect the hdp
|
|
|
|
dumper command was not valid. It now detects and reports the
|
|
|
|
failure of hdp execution.

C. 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.
|
|
|
|
|
|
|
|

|
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.

====================================================================
|
2000-03-24 05:34:06 +08:00
|
|
|
|
|
|
|
* 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.

2. Changes from the Second Alpha 1.0.0 Release to the Beta 1.0.0 Release
|
|
|
|
=========================================================================
|
2000-03-24 05:34:06 +08:00
|
|
|
|
|
|
|
* 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.

|
|
|
|
|
2003-06-03 04:36:31 +08:00
|
|
|
1. Changes from the First Alpha 1.0.0 Release to
|
2001-01-26 06:33:47 +08:00
|
|
|
the Second Alpha 1.0.0 Release
|
2003-06-03 04:36:31 +08:00
|
|
|
=====================================================================
|
2000-03-24 05:34:06 +08:00
|
|
|
|
|
|
|
* 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
|
|
|
