| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 some mpi-io packages that don't support collective IO for no IO 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.

Bug fix on the H5T_vlen_set_loc to allow for changing the file on a variable-length datatype on disk.

* [svn-r11894] Purpose:Leon Arber2006-01-263-12/+137
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Feature, address bug #426 Description: The h5perf test now also keeps track of the time it takes to: open a file: Time between start of open and start first read/write close a file: Time between end of last read/write and end of close. This information is only displayed if debug output printing is enabled (level 3 or higher) Solution: The test actually has all of the data necessary to compute the time it takes to open and close a file; it just wasn't recording it. Added 4 new timers: HDF5_FILE_READ_OPEN HDF5_FILE_READ_CLOSE HDF5_FILE_WRITE_OPEN HDF5_FILE_WRITE_CLOSE that keep track of the time to open/close a file opened for reading/writing. Platforms tested: heping and mir Misc. update:
* [svn-r11891] Purpose: Small bug fixElena Pourmal2006-01-251-1/+3
| | | | | | | | | | | | | | | | Description: h5_group example didn't work on VMS; it turned out that a group was not closed and since the default file close degree is "weak", file was not closed either. When program attempted to open the same file, system reported an error since the file was "locked by another user". UNIX systems apperently do not care and open the same file without any problem. Solution: Added H5Gclose calls. Platforms tested: VMS server and heping Misc. update:
* [svn-r11889] Purpose:Quincey Koziol2006-01-241-0/+1
