* [svn-r24878] Description:Quincey Koziol2014-03-241-1/+0
| | | | | | | | | | | | | | | | | | | | | Bring r24864 from trunk to 1.8 branch: Remove all traces of MPI-POSIX VFD and GPFS detection/code. Remove remaining traces of stream VFD. Remove testpar/t_posix_compliant test (it's not actually verifying anything). Clean up H5D__mpio_opt_possible() further. Moved environment variable that disables MPI collective operations into MPI-IO VFD (instead of it being in src/H5S.c). A few other small code cleanups. Tested on: Mac OSX/64 10.9.2 (amazon) w/parallel & serial (daily tested on trunk)

* [svn-r14861] Description:Quincey Koziol2008-04-241-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Bring revision 14860 back to 1.8 branch, change log for rev 14860 is: Omnibus raw data I/O revisions, with wide-ranging changes and refactoring, in order to prepare for implementing "fast append" feature. These changes remove the majority of the code duplication for raw data I/O which has crept in over the last ten years and introduces a more object- oriented design for operating on different types of dataset storage. Description: Omnibus raw data I/O revisions, with wide-ranging changes and refactoring, in order to prepare for implementing "fast append" feature. These changes remove the majority of the code duplication for raw data I/O which has crept in over the last ten years and introduces a more object- oriented design for operating on different types of dataset storage. Chunked storage no longer has it's own I/O routines, it is now handled as either contiguous (if chunk is not pulled into the cache) or compact (if the chunk is cached in memory). No bug or feature changes, at least intentionally... :-) Tested on: Mac OS X/32 10.5.2 (amazon) w/production

| | | | | | | | | copyright notice. Tested platform: Kagiso only since it is only a comment block change. If it works in one machine, it should work in all, I hope. Still need to check the parallel build on copper.
* [svn-r12553] This check-in includes the following part of parallel ↵MuQun Yang2006-08-091-4/+10
| | | | | | | | | | | | | | | optimization codes: 1. Provide another option for users to do independent IO with MPI file setview(collectively) 2. With the request of collective IO from users, using Independent IO with MPI file setview if we find collective IO is not good for the applications for IO per chunk(multi-chunk IO) case. Previously we used pure independent IO and that actually performed small IO(IO each row) for this case. The recent performance study suggested the independent IO with file setview can acheieve significantly better performance than collective IO when not many processes participate in the IO. 3. For applications that explicitly choose to do collective IO per chunk case, the library won't do any optimization(gather/broadcast) operations. The library simply passes the collective IO request to MPI-IO. Tested at copper, kagiso, heping, mir and tungsten(cmpi and mpich) Kagiso is using LAM, t_mpi test was broken even. The cchunk10 test failed at heping and mir. I suspected it was an MPICH problem. Will investigate later. Everything passed at copper. at tungsten: the old cmpi bug(failed at esetw) is still there. Other tests passed. Some sequential fheap tests failed at kagiso.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some collective chunk IO macro names are confusing, change them to more meaningful names. Description: H5Pset_dxpl_mpio_chunk_opt will set a flag so that the library can do one linked IO or multi-chunk IO with collective in chunking storage directly. That is, the library won't do analyses to determine this. The flags for the enum type we used before are: H5FD_MPIO_OPT_ONE_IO H5FD_MPIO_OPT_MULTI_IO They are not good names because of the following two reasons: 1. It doesn't reflect chunking storage 2. OPT is kind of redundant and misleading, Solution: We change the names to H5FD_MPIO_CHUNK_ONE_IO H5FD_MPIO_CHUNK_MULTI_IO Platforms tested: Since only macro names are changed, no need to test with h5committest. heping(mpich 1.2.6) Misc. update:

| | | | | | | | | | | | | Code maintenance Description: Remove flexible parallel code Platforms tested: FreeBSD 4.11 (sleipnir) Linux 2.4 (heping) Solaris 2.9 (shanti) Linux 2.4/64 (mir)
* [svn-r12090] Purpose:MuQun Yang2006-03-141-0/+22
| | | | | | | | | | | | | | | | | | | New APIs to add for collective chunk IO Description: Three new APIs H5Pset_dxpl_mpio_chunk_opt_ratio H5Pset_dxpl_mpio_chunk_opt_num H5Pset_dxpl_mpio_chunk_opt for optional optimization choices from users. Solution: Haven't added tests yet, won't affect other parts of the library. Will add tests after urgent investigations of memory leaking problems from NASA Aura team. Platforms tested: heping: both parallel and sequential shanti Misc. update:
* [svn-r8981] Purpose:Quincey Koziol2004-08-021-1/+0
| | | | | | | | | | | | | Code cleanup Description: Various minor tweaks to clean code up and bring it into closer syncronization with the release branch. Platforms tested: FreeBSD 4.10 (sleipnir) w/parallel h5committested IRIX64 6.5 (modi4)
* [svn-r8134] Purpose:Quincey Koziol2004-01-311-1/+1
| | | | | | | | | | | | | | | | Code cleanup Description: Add destructor to match constructor fr VFLs when they are shut down by the library. Solution: Added H5FD_*_term() routines to "undo" changes made in H5FD_*_init() routines. Platforms tested: IBM p690 (copper) too minor to require h5committest
* [svn-r8130] Purpose:Quincey Koziol2004-01-311-2/+2
| | | | | | | | | | | Bug fix Description: Address the failure in the FORTRAN builds by making some more of the MPI-related typedefs in the library available outside of parallel builds. Platforms tested: Linux 2.4 (verbena) w/FORTRAN & C++
* [svn-r8127] Purpose:Quincey Koziol2004-01-311-5/+7
| | | | | | | | | | | Bug fix Description: Fix a couple of bugaboos in the serial build that crept in Platforms tested: FreeBSD 4.9 (sleipnir) too minor to require h5committest
* [svn-r8126] Purpose:Quincey Koziol2004-01-311-0/+93
Bug fix/optimization Description: Address slowdown in MPI-I/O file metadata operations that was introduced mid-stream. We now _require_ a POSIX compliant parallel file system for the MPI-I/O file driver (as well as for the MPI-POSIX file driver). Also optimized file open operation when the file is being created by reducing the number of collective & syncronizing calls. Additionally, refactor the MPI routines into a common place, eliminating duplicated code. Platforms tested: FreeBSD 4.9 (sleipnir) w/parallel h5committest
