Multi Dataset (#2120)
* Fix bug with cross platform compatibility of references within vlens.
No testing yet.
* Merge from multi_rd_wd_coll_io to a more recent branch from develop.
Untested, probably does not work yet.
* Committing clang-format changes
* Committing clang-format changes
* Fix many bugs in multi dataset branch. Mostly works, some issues in
SWMR tests.
* Committing clang-format changes
* Disable test in swmr.c that was failing due to bug in HDF5 unrelated to
multi dataset.
* Committing clang-format changes
* Fixed fortran multi-dataset tests
* Fixed xlf errors
* Added benchmark code for multi-datasets
* loops over datasets
* added missing error arg.
* Added gnuplot formatting
* Jonathan Kim original MD benchmarking code
* updated MD benchmarking code
* code clean-up
* Only make files in feature test mode
* misc clean-up
* removed TEST_MDSET_NO_LAST_DSET_2ND_PROC option
* Committing clang-format changes
* Change multi dataset API to use arrays of individual parameters instead
of the parameter struct.
* Committing clang-format changes
* Update to new multi dataset Fortran API and tests. (#1724)
* Update to new multi dataset Fortran API and tests.
* Sync Fortran with develop.
* skipping h5pget_mpio_actual_io_mode_f for now
* Fixed issue with dxpl_id, changed to variable size dim. (#1770)
* Remove "is_coll_broken" field from H5D_io_info_t struct
* Committing clang-format changes
* Minor cleanup in multi dataset code.
* Committing clang-format changes
* Clean up in multi dataset code.
* Committing clang-format changes
* Committing clang-format changes
* Fix speeling
* Fix bug in parallel compression. Switch base_maddr in io_info to be a
union.
* Committing clang-format changes
* Implement selection I/O support with multi dataset. Will be broken in
parallel until PR 1803 is merged to develop then the MDS branch.
* Committing clang-format changes
* Spelling
* Fix bug in multi dataset that could cause errors when only some of the
datasets in the multi dataset I/O used type conversion.
* Committing clang-format changes
* Integrate multi dataset APIs with VOL layer. Add async versions of
multi dataset APIs.
* Committing clang-format changes
* Spelling fixes
* Fix bug in non-parallel HDF5 compilation.
* Committing clang-format changes
* Fix potential memory/free list error. Minor performance fix. Other minor
changes.
* Committing clang-format changes
* Fix memory leak with memory dataspace for I/O.
* Committing clang-format changes
* Fix stack variables too large. Rename H5D_dset_info_t to
H5D_dset_io_info_t.
* Committing clang-format changes
* Remove mem_space_alloc field from H5D_dset_io_info_t. Each function is
now responsible for freeing any spaces it adds to dset_info.
* Committing clang-format changes
* fixed _multi Fortran declaration
* Refactor various things in (mostly) the serial I/O code path to make
things more maintainable.
* Committing clang-format changes
* updated to array based, doxygen, and examples
* Reinstate H5D_chunk_map_t, stored (via pointer) inside
H5D_dset_io_info_t.
* Change from calloc to malloc for H5D_dset_io_info_t and H5D_chunk_map_t.
Switch temporary dset_infos to be local stack variables.
* Committing clang-format changes
* format cleanup
* format cleanup
* added coll and ind
* Modify all parallel I/O paths to take dset_info instead of assuming
dset_info[0].
* Committing clang-format changes
* fixed output
* Rework parallel I/O code to work properly with multi dataset in more
cases. Fix bug in parallel compression.
* Committing clang-format changes
* Prevent H5D__multi_chunk_collective_io() from messing up collective opt
property for other datasets in I/O. Other minor cleanup. Add new test
case to t_pmulti_dset.c for H5FD_MPIO_INDIVIDUAL_IO, disabled for now
due to failures apparently unrelated to multi dataset code.
* Fix spelling
* Committing clang-format changes
* Replace N log N algorithm for finding chunk in
H5D__multi_chunk_collective_io() with O(N) algorithm, and remove use of
io_info->sel_pieces in that function.
* Committing clang-format changes
* Replace sel_pieces skiplist in io_info with flat array of pointers, use
qsort in I/O routine only when necessary.
* Committing clang-format changes
* Add new test case to mdset.c
* Committing clang-format changes
* Fix spelling
* Very minor fix in H5VL__native_dataset_read()
* Fix bug that could affect filtered parallel multi-dataset I/O.
* Add RM entries for H5Dread_multi(), H5Dread_multi_async(),
H5Dwrite_multi(), and H5Dwrite_multi_async()
* Unskip test in swmr.c
* Committing clang-format changes
* Eliminate H5D__pre_read and H5D__pre_write
* Remove examples/ph5mdsettest.c. Will fix and re-add as a test.
* Enable hyperslab combinations in mdset test
* Committing clang-format changes
* Clarify H5Dread/write_multi documentation.
* Fix bugs in multi-dataset I/O. Expand serial multi dataset test.
Update macro in parallel multi dataset test.
* Committing clang-format changes
* Spelling
* Remove obsolete entry in bin/trace
* Rework type conversion buffer allocation. Only one buffer is shared
between datasets in mdset mode, and it is malloced instead of calloced.
* Committing clang-format changes
