Code checkpoint
Description:
Check in fractal heap code to add basic support for skipping direct blocks
when an object is too large to fit in one.
Platforms tested:
FreeBSD 4.11 (sleipnir)
Linux 2.4 (chicago)
Code checkpoint
Description:
Checkpoint fractal heap code at a stable point in development. It appears
that adding objects to heaps and reading them back out is now working
properly (as long as there are no gaps in the heap and no standalone objects
are created).
Platforms tested:
FreeBSD 4.11 (sleipnir)
Linux 2.4 (chicago)
Linux 2.4 (mir) w/64-bit & FORTRAN & C++
Solaris 9 (shanti) w/64-bit
bug fix
Description:
h5repack was not dealing with family files
Solution:
use the toolslib function h5tools_open to open the file instead of H5Fopen in h5repack
Platforms tested:

Misc. update:

Description:

Code optimization
Description:
Tweak file free space allocation routines to optimize them a bit.
Platforms tested:
FreeBSD 4.11 (sleipnir)
Too minor to require h5committest
Removed -march flag
Description:
The -march optimization flag is bad in some circumstances
Solution:
Prevented HDF5 from adding the -march archicture-specific optimization
flag, so that users could have one version of HDF5 used by
several different machines.
Platforms tested:
heping (one of the few platforms that affected by this small change)
Description: cross_read.c is a new program to test reading data created
on an OpenVMS, a little-endian, and a big-endian machine. The three
data files are vms_data.h5, be_data.h5, and le_data.h5. To generate
these data files, run gen_cross.c on these machines and change the file
names.
Platforms tested: fuss and h5committest
Misc. update: MANIFEST
Bug fix
Description:
Previous checkin did a bad thing; 'make clean' failed in example directories.
Solution:
Fixed commence.am so that examples no longer break, and fixed a mistake
in conclude.am.
Platforms tested:
heping (minor makefile change)
Misc. update:
Add tests for optional APIs to support collective chunk IO
Description:
In order to test whether library picks up the user's options,
The number of chunks need to be varied for different processes,
Selection of the number of processes selected in one chunk also
need to be varied.
Solution:
Create two cases,
1. Each chunk only selected by one unique process, this case
library should use independent for collective call.
2. One-third of the processes occupies the top half of the whole domain,
The rest of the processes occupies the lower half of the domain.
The total number of chunk is a fixed number 8.
Platforms tested:
Linux 2.4 with mpich 1.2.6(only)
Since I only checked in the code that handles the selection, haven't added any new tests yet. So it won't affect any platforms.
Misc. update:

Description:

Description:

Also a little Makefile cleanup.

change the array size of collective chunking features of parallel tests.
Description:
Previously array size for collective optimization tests
including
cchunk1,
cchunk2,
cchunk3,
cchunk4,
ccontw,
ccontr,
cschunkw,
cschunkr,
ccchunkw,
ccchunkr
are fixed,
They are only valid for some good number of processors(1,2,3,4,6,8,12,16,24,32,48 etc).
Recently there are more requests for parallel tests to be valid on some odd number of processes such as 5,7,11,13 etc.
Solution:
I change the array size to be dynamic rather than static. Now the fastest change array size is a function of mpi_size. dim2 = constant *mpi_size. After some tunings, theoretically the above tests should be valid for any number of processors. However, other parallel tests still need to be tuned.
To verify the correctness of these tests, using mpirun -np 5 ./testphdf5 -b cchunk1 at heping.
Platforms tested:
h5committest(shanti is refused to be connected)
at heping, 5 and 7 processes are used to verify the correctness.
Misc. update:
portable issue on windows
Description:
setvbuf on visual studio 2005 needs the size to be greater or equal to 2.
<description of setvbuf from msdn library>
Buffer size in bytes. Allowable range: 2 <= size <=
INT_MAX (2147483647). Internally, the value supplied
for size is rounded down to the nearest multiple of 2.
h5import used linebuffer option of setvbuf for stderr and stdout and the size is
0 by default. This causes core dump with visual 2005 on windows 64-bit.
Solution:
1. Use HDsetvbuf inside h5import.c,
2. Define HDsetvbuf inside windows H5pubconf.h for windows to work around
the core dump of h5import test. This is probably a bug inside visual studio 2005.

Misc. update:
Description: Unix remove function removes only the latest version of a file
on VMS. Some of our tests create multiple versions of the testfiles
and as a result, test programs may be confused, give false negative result,
etc.
Solution: Created HDremove_all function for VMS that removes all versions of the files.
HDremove on VMS is an alias to HDremove_all.
Platforms tested: VMS server and heping (to check that nothing is borken on UNIX side)
Misc. update:
Description: OpenVMS doesn't support denormalized floating-point values.
Disable the denormalized and special values for floating to floating-point
tests.
Platforms tested: OpenVMS - the only concerned machine.
Misc. update:

Bug fix
Description:
The snapshot script was trying to install-doc, even though the docs are
no longer included in the cvs repo.
Solution:
Replaced 'make install install-doc' with 'make install-all', which should

Too minor to require h5committest
Description: VMS stat structure doesn't have st_blocks filed. H5_HAVE_STAT_ST_BLOCKS
was defined in h5pubconf.h and therefore compilation of big.c
failed on VMS.
Solution: Undefined H5_HAVE_STAT_ST_BLOCKS in h5pubconf.h
Platforms tested: VMS server (change is local to VMS only)
Misc. update:
Description: Linking of cache test failed on VMS due to the missing
cache_common.* files
Solution: Added cache_common.* files to the approriate places in the make.com file.
Platforms tested: VMS server (this change is for VMS only)

Enhancing the optimiziation of collective IO per chunk
Description:
When the user does one of the following two things:
1. to do collective IO per chunk without using our optimization code
2. or the user passes the percent of number of process per chunk to be 0 when choosing
to do collective IO per chunk
It is not necessary that the library uses MPI-IO collective calls to do any optimization.
Solution:
Modify the code so that no MPI communication-involved analyses will be done for the above cases. Chunk addresses are obtained globally and IO modes are assigned to collective always.
Platforms tested:
h5committest
Misc. update:
Description: Yesterday, H5E_NONE_MAJOR and H5E_NONE_MINOR were added to error
API by hand.
Solution: Today, correct the change by hand with the tool hdf5/bin/make_err.
The change by hand is only in src/H5err.txt.
Platforms tested: fuss - simple change.
