* [svn-r24878] Description:Quincey Koziol2014-03-241-4/+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-r24785] Description:Quincey Koziol2014-03-121-6/+7
| | | | | | | | | | | | | Bring r24769 & r24772 from trunk to 1.8 branch: Check in Mohamad's changes to support collective I/O on point selections, along with some other minor cleanups. Correct some dynamically sized arrays that fail on Windows. Tested on: Mac OSX/64 10.9.2 (amazon) w/parallel (And has been through the daily test regime on the trunk)

* [svn-r19093] Description:Quincey Koziol2010-07-191-11/+10
| | | | | | | | | | | | | | | | | | | | Bring r19092 from trunk to 1.8 branch: Bring "shape same" changes from LBL branch to trunk. These changes allow shapes that are the same, but projected into dataspaces with different ranks to be detected correctly, and also contains code to project a dataspace into greater/lesser number of dimensions, so the I/O can proceed in a faster way. These changes also contain several bug fixes and _lots_ of code cleanups to the MPI datatype creation code. Many other misc. code cleanup are included as well...

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

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | New feature Description: Check in baseline for compact group revisions, which radically revises the source code for managing groups and object headers. WARNING!!!! WARNING!!!! WARNING!!!! WARNING!!!! WARNING!!!! WARNING!!!! WARNING!!!! WARNING!!!! WARNING!!!! WARNING!!!! WARNING!!!! WARNING!!!! This initiates the "unstable" phase of the 1.7.x branch, leading up to the 1.8.0 release. Please test this code, but do _NOT_ keep files created with it - the format will change again before the release and you will not be able to read your old files!!! WARNING!!!! WARNING!!!! WARNING!!!! WARNING!!!! WARNING!!!! WARNING!!!! WARNING!!!! WARNING!!!! WARNING!!!! WARNING!!!! WARNING!!!! WARNING!!!! Solution: There's too many changes to really describe them all, but some of them include: - Stop abusing the H5G_entry_t structure and split it into two separate structures for non-symbol table node use within the library: H5O_loc_t for object locations in a file and H5G_name_t to store the path to an opened object. H5G_entry_t is now only used for storing symbol table entries on disk. - Retire H5G_namei() in favor of a more general mechanism for traversing group paths and issuing callbacks on objects located. This gets us out of the business of hacking H5G_namei() for new features, generally. - Revised H5O* routines to take a H5O_loc_t instead of H5G_entry_t - Lots more... Platforms tested: h5committested and maybe another dozen configurations.... :-)

Description: Prior to this checkin, management of the is_dirty flag was handled above the level of the metadata cache. This can no longer be allowed, as it introduces a race condition in the proposed fix for a cache coherency bug in PHDF5. Solution: Move management fo the is_dirty flag to the cache code proper.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Bug Fix/Code Cleanup/Doc Cleanup/Optimization/Branch Sync :-) Description: Generally speaking, this is the "signed->unsigned" change to selections. 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. I've also tagged the repository before making this checkin with the label "before_signed_unsigned_changes".

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. Platforms tested: FreeBSD 4.10 (sleipnir) w/parallel IBM p690 (copper) w/parallel

| | | | | | | | | | | | | | Description: This is the second step of checkin for encoding and decoding objects. H5Tencode and H5Tdecode have been committed in the previous step. H5Sencode and H5Sdecode are checked in this time. Solution: Given object ID, these functions encode and decode object information into and from binary buffer and return new object ID. They take advantage of the existing codes of object header message and encode in the same format. Platforms tested: fuss and h5committest. Misc. update: RELEASE.txt

| | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | Code cleanup & minor optimization Description: Re-work the way interface initialization routines are specified in the library to avoid the overhead of checking for them in routines where there is no interface initialization routine. This cleans up warnings with gcc 3.4, reduces the library binary size a bit (about 2-3%) and should speedup the library's execution slightly.

* [svn-r8677] Purpose:Quincey Koziol2004-06-141-1/+1
| | | | | | | | | | | | | | | | | | | Code cleanup & optimization Description: Remove old structures that used a union to store information about the dataspace extent and just store the information directly in the dataspace extent itself. Remove ifdef'd references to permutation ordering in dataspaces. We'll definitely need more than this code if/when we implement this feature. Change allocation of dataspace information from calloc() to malloc(). Platforms tested: Solaris 2.7 (arabica) FreeBSD 4.10 (sleipnir) w/parallel Too minor to require h5committest
