Description:

bug fix
Description:
ret_value is not set to SUCCEED in H5D_mpio_select_write
That causes the 64-bit intel compiler unhappy.
It will give a non-zero number and cause the testing fake failure.
Another one is picked up by cmpi again. For one optimization case,
another variable is not initialized properly and compiler set an unhappy number,
cause the test failed.
Solution:
Properly initialize those variables.
Platforms tested:
teragrid:parallel
mir:parallel
heping: parallel and sequential
tungsten:parallel
Misc. update:
h5committest doesn't finish due to no space left on device.
parallel tests still failed at tungsten with cmpi. It looks like it was a bug from cmpi.

bug fix for daily test
Description:
if (fm->select_chunk) is not NULL at sequential mode and not set by the library, it shouldn't be free.
Otherwise, it will cause failures in the daily test.
Solution:
Explicitly set (fm->select_chunk) to NULL for non-parallel case.
Platforms tested:
copper with parallel
heping with both sequential and parallel
shanti with sequential
Misc. update:
Hopefully only mir failed at daily test.

Bug fix in collective IO code
Description:
When select none occurs in one process, fm->select_chunk hasn't been allocated the memory(not allocated until create_file_hyper); however, this needs to be checked; it was caught with cmpi at NCSA linux cluster.
Solution:
Relocate the place to allocate the memory space for fm->select_chunk.
Platforms tested:
cmpi at tungsten
mpich at heping
kind of minor and let daily test catch other errors.
Misc. update:
This won't fix the failure at mir.

bug fix
Description:
During the process of the combination of collective chunk IO code and the original IO code,
The return value of a function call hasn't been initialized. On 32-bit mode at modi4, that value isn't set to 0 by default. So a fake error value returns.
Solution:
Re-arrange the code so that the return value will be set properly.

Change to release script
Description:
Silenced doxygen's output when bin/release doc is run. Now if doxygen
has an error the release script will exit.
Someone forgot to run reconfigure after a Makefile.am, so testing the
release script seems to have had the side effect of regenerating a
Makefile.in.

Enhanced collective chunk IO supports
Description:
1. When using collective IO with chunking storage without any tuning, performance may become worse under some circumstances.
2. Current HDF5 handles raw-data IO per chunk. So for many small chunks, many small IOs will be passed into MPI-IO. That may cause bad performance.
3. For one IO per chunk case, sometimes performance with collective is worse than performance with independent. An obvious case is when only one process is doing IO and all other process are not doing IO, the collective IO will only add overheads for communication. We want to avoid this case. Some management inside our library needs to be done.
Solution:
- Added managements of collective IO supports for chunking storage
inside parallel HDF5
1) Implemented One IO with collective mode for all chunks in the
application by building one MPI derived datatype accross all
chunks.
2) Implemented the decision-making support to do collective IO inside
MPI-IO per chunk.
3) Added the decision-making support to do one IO accross all chunks
or to do multiple IOs with each IO per chunk.
4) Added the support to handle the case some processes won't do any IOs in
collectively.
5) Some MPI-IO package(mpich 1.2.6 or lower, e.g.) cannot handle
collective IO correctly for the case when some processes have no
contributions to IOs, a special macro is added to change
collective IO mode to independent IO mode inside HDF5 library.

Add collective chunk IO supports
Description:
Added a macro hdf5_mpi_special_collective_io_works to filter out

contributions in some processes.
Solution:
1.
"hdf5_mpi_special_collective_io_works=${hdf5_mpi_special_collective_io_works=
'no'}"
has been added at the end of file ia64-linux-gnu and linux-gnulibc1
2. Some comments are added in ia64-linux-gnu and linux-gnulibc1.
3. Documents are added inside RELEASE.txt.

Description:
v1.7:
Removed some debug files left by previous change.
Uncommented the removal of the temporary working directory.
v1.6:
Moved the code of removal of the temporary working directory
to a later location in order to stay in sync with v1.7.
(The later location is needed for v1.7 code but makes no different
to v1.6)
