feature change, new feature.
Description:
Had the HDF5_PARAPREFIX default set to /tmp.
Changed it to null so that data files are created in current directory
by default.
Also added a code to print data filename used when debug level > 0.
Platforms tested:
Tested in modi4 parallel.

Code cleanup
Description:
Remove the fill-value option entirely, since the 1.5.x library's default
behavior is now the same as the 1.4.x behavior and also there is no
corresponding code for implementing fill-values with the POSIX or MPI-I/O tests.
Platforms tested:
FreeBSD 4.8 (sleipnir) w/parallel
too small to need h5committest

Code cleanup

Bug Fix
Description:
On HP-UX platforms, the "open()" function needs to specify that the
file being created has permissions S_IRWXU, which means that it gives
read/write/execute permissions to the user who created the file (how
nice of it!).
Solution:
Added the S_IRWXU flag to the open() function call.
Platforms tested:
HP-UX 11
Arabica,
Modi4,
Verbena

Compatibility fix
Description:
The H5P[set|get]_fapl_mpiposix calls changed between v1.4.x and v1.5.x.
Solution:
Wrap them in the v1.4 backward compatibility #ifdefs and update tests, etc.
Platforms tested:
FreeBSD 4.8 (sleipnir) w/paralle & v1.4 compatibility
h5committest pointless

"Bug fix"
Description:
This version is showing very slow HDF5 I/O write speeds (about 40%
of MPIO). It was because the library is writing fill values by
default. There is a no-fill option which set to FALSE. Changed
it to TRUE since MPIO and POSIX are not doing fill values.
This is just a stop gap fix since the better fix would be to
change the library to not write fill-values in this case.
Platforms tested:
modi4 parallel and LANL Q paralllel.
No h5committest test because it is very trivia.
Misc. update:

|
|
|

Purpose:
Added sanity check that min number of processes be not greater
than max number of processes.
Platforms tested:
copper only since this is a very simple change.

Bug fix.
Description:
The default setting of max transfer size is larger than
the default setting of number of bytes per process, result
in complaints that Transfer size is too big.
Solution:
Cap the min and max transfer size with number of bytes per process.
Always cap min transfer size with the max xfer size.
Platforms tested:
Copper.

Code Improvements/Bug Fixes

positive number.

Bug Fix
Description:
When I changed the H5P{set,get}_fapl_mpiposix functions to accept
another parameter, I didn't change it in these files.
Solution:
Added the new "use_gpfs" parameter.

Add multi-D hyperslab benchmark to repo. It's not hooked up to any makefiles
yet, so it's not being compiled or tested, etc. I'm just stashing it here

Update, Bug Fix, and Feature Add
Description:
- Updated how AC_{ENABLE,WITH} help messages were being generated.
Autoconf now gives you an AC_HELP_STRING macro to use to create
them.
- Fixed the problem with Linux LFS on RedHat 7.3 machines. It wasn't
finding getdents64(), so we can't rely on that being present
anymore...
- Added GPFS detection and setting.
- Updated how compression is specified. It's no longer necessary to
test for HAVE_ZLIB_H, HAVE_LIBZ, and HAVE_COMPRESS2. The one macro
{H5_}HAVE_COMPRESSION takes care of all of these.
Solution:
Changed the check for Linux LFS from looking for getdents() to
looking at the version number of the kernel (using the uname -r
command). You can still override with the --enable-linux-lfs switch
if you really believe that your <2.4 kernel has LFS support.
Platforms tested:
Linux (2.2 and 2.4)
