Optimize chunked dataset fill operation by making it collective.
+ add a workaround for new algorithm to work with ompi.
Update RELEASE.txt with this new optimization.
Merged r25508 from the trunk.
Adds a check that ensure the page_size parameter in
H5Pset_core_write_tracking is not zero. This ensures that the behavior
matches the text in the reference manual.
Tested on:
32-bit LE linux (jam), tested with make check-vfd.
This is a very minor change and does not require full testing.
Reviewed and revised version information for unix daily tested machines in supported a
d tested platforms sections.
Added description of LD_LIBRARY_PATH change to configure and using scripts to compile
nd run installed example files to Bug Fixes/Configuration section.
Text change only.
Merged r24993 from the trunk.
Adds core VFD write tracking functionality. When enabled, the core VFD
will track dirty regions of the file and only write out the changed
regions. The new H5Pget/set_core_write_tracking() API call controls this
feature. A new "core_paged" VFD target was added to the check-vfd target
in test/Makefile.am that runs all tests with the new write tracking
functionality.
Tested on:
32-bit LE linux (jam)
64-bit LE linux (koala)
64-bit BE linux (ostrich)
Each platform was tested with HDF5_DRIVER set to "core" and "core_paged".
Jam was also tested with the standard sec2 driver.
Merged r24893, r24961, r24965 from trunk.
Fix for thread-local storage resource leaks on Windows with Win32 threads.
Prohibits thread-safe + C++/Fortran/static library in CMake.
Tested on:
64-bit Windows 7 w/ Visual Studio 2012
Merged r24857 from the trunk.
Changes to configure.ac so that --with-pthreads is not required
when the --enable-threadsafe configure option is set as long as
the Pthreads library is in a standard location.
Tested on:
32-bit LE linux (jam) with --enable-threadsafe
64-bit LE linux (koala) with --enable-threadsafe
64-bit BE linux (ostrich) with --enable-threadsafe
Merge of r24937 from the trunk
Adds H5free_memory to the API. This function should be used to free
memory allocated by the library (e.g., returned values from
H5Tget_tag, H5Pget_class_name, etc.).
This is mainly to help Windows applications deal with multiple CRT
instances, but can also be helpful when a debug memory manager is
being used or when the HDF5 API is being wrapped for managed languages
like Python and Java.
Tested on:
32-bit LE linux (jam) with fortran and C++
64-bit BE linux (ostrich)
64-bit LE linux (koala)
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)
