| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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: FreeBSD/32 6.2 (duty) in debug mode FreeBSD/64 6.2 (liberty) w/C++ & FORTRAN, in debug mode Linux/32 2.6 (kagiso) w/PGI compilers, w/C++ & FORTRAN, w/threadsafe, in debug mode Linux/64-amd64 2.6 (smirom) w/default API=1.6.x, w/C++ & FORTRAN, in production mode Linux/64-ia64 2.6 (cobalt) w/Intel compilers, w/C++ & FORTRAN, in production mode Solaris/32 2.10 (linew) w/deprecated symbols disabled, w/C++ & FORTRAN, w/szip filter, in production mode Mac OS X/32 10.5.2 (amazon) in debug mode Linux/64-ia64 2.4 (tg-login3) w/parallel, w/FORTRAN, in production mode

| | | | | | | | | | | | | | | | | | | | | | | bug fix for collective chunk IO, phase 1 Optimization hasn't been done yet, the collective chunk IO bug should be fixed. Description: In chunking storage, memory space and file space will be remapped, So to check whether file space and memory space are regular in order to use optimized MPI derived datatype for collective call one has to check per-chunk wise instead of per hyperslab wise. Even a regular memory space will be stored in span-tree and will be irregular before chunk IO. Solution: 1. Check file space and memory space per chunk wise instead of per hyperslab wise. 2. For collective IO mode, number of chunks covered by hyperslab may be different. Since we are handing per chunk per IO, for the extra chunk IO for some(not all) processors, collective mode will cause program hanged. So for the extra chunk Io mode independent IO has to be used. 3. On some platforms, Complex MPI derived datatype is not working, so we have to use independent IO for collective IO mode if the selection is irregular. However, when the selection is regular, we do want to use collective IO since that will improve performance. Special cares have to be added for this case.

| | | | | | | | | | | | | | | | | | | | | | | | Activating collective IO supports for irregular selction inside HDF5 dataset. This support doesn't include to build the final complicated MPI derived datatype support for chunking storage. Description: Support collective chunk IO for both contiguous and chunking storage for irregular selection( using H5S_SELECT_OR for multiple hyperslab selection) Solution: Using MPI derived datatype to realize this feature. Problems still need to be investigated: Big size irregular hyperslab selection test may cause MPI hang or abnormalexit with MPICH family on various platforms. This is really hard to debug since sometimes it can work and sometimes it cannot work. We will continue investigating those cases. This may not be parallel HDF5 bugs since with the recent version of poe at IBM platforms, all tests passed. Platforms tested: 1. Linux heping 2.4.21-27.0.1 with mpich 2. AIX 5.1 copper with mpcc_r 3.

However, in the process of merging code back, things got stickier and stickier until I ended up doing a big "sync the two branches up" operation. So... I brought back all the "infrastructure" fixes from the development branch to the release branch (which I think were actually making some improvement in performance) as well as fixed several bugs which had been fixed in one branch, but not the other.

| | | | | | | | | | | | | | | | | | | | | | | | | | Bug fix (Failures when dataset size >= 1 GB, reported by Bill Loewe.) Description: In the IBM AIX system using 32bit mode, if a dataset size was 1GB or larger, when the "end" of the dataset was selected, MPI would complain it could not keep the Upper bound of a datatype within the range of MPI_Aint. This was because the old algorithm would derive the selection with extent of each row first. After all dimensions were processed, it then calculate the start position and just displace the whole MPI derived type. So, the final MPI type was actually the start position plus the whole dataset. Since the start can be as big as the whole dataset, this made the final derived twice as big as 1GB. That would hit the 2GB MPI_Aint range limit in the 32 bit mode. Solution: Use a different algorithm to include the start position in the defining of MPI type for each dimension. When all dimensions are processed, the MPI type represents the selection exactly.

| | | | | | | | | | | | | | | | | | | | Code cleanup Description: Clean up collective chunking code a bit. Also, add '--enable-instrument' configure flag to have a mechanism for determining that optimized operations happened correctly in the library (instead of just the "normal" way) by allowing 'flag' properties to be set outside the library and set when the "right" thing happens. This is mainly for debugging and regression checks, so we make certain we don't break optimized I/O by accident. It's enabled by default when --enable-debug is on (which is on by default in the development branch and off by default in the release branch), but can also be independently controlled with its own configure flag.

| | | | | | | | | | | | | | | | | | | | | | | Adding the first round of patches about supporting collective chunk IO in HDF5 Description: The current HDF5 library doesn't support collective MPIO with chunk storage. When users set collective option in their data transfer with chunk storage, the library silently converted the option to INDEPENDENT and that caused trememdous performance penalty. Some application like WRF-parallel HDF5 IO module has to use contiguous storage for this reason. However, chunking storage has its own advantage(supporting compression filters and extensible dataset), so to make collective MPIO possible inside HDF5 with chunking storage is a very important task. This check-in make collective chunk IO possible for some special cases. The condition is as follows(either case is fine with using collective chunk IO) 1. for each process, the hyperslab selection of the file data space of each dataset is regular and it is fit in one chunk. 2. for each process, the hyperslab selection of the file data space of each dataset is single and the number of chunks for the hyperslab selection should be equal. Solution: Lift up the contiguous storage requirement for collective IO. Use H5D_isstore_get_addr to get the corresponding chunk address. Then the original library routines will take care of getting the correct address to make sure that MPI FILE TYPE is built correctly for collective IO> Platforms tested: arabica(sol), copper(AIX), eirene(Linux) parallel test is checked at copper.
