From 0aa8d4d88a7d90cbb841bafacf54d97bc1d7a3f7 Mon Sep 17 00:00:00 2001 From: Jonathan Kim Date: Tue, 4 Sep 2012 12:00:38 -0500 Subject: [svn-r22735] Purpose: HDFFV-8143 Provide a routine(s) for telling the user why the library broke collective data access Description: Added H5Pget_mpio_no_collective_cause() function that retrive reasons why the collective I/O was broken during Read/Write IO access. Reasons to break collective I/O: - SET_INDEPENDENT - DATATYPE_CONVERSION - DATA_TRANSFORMS - MPIPOSIX - NOT_SIMPLE_OR_SCALAR_DATASPACES (NULL Space) - POINT_SELECTIONS - NOT_CONTIGUOUS_OR_CHUNKED_DATASET (Compact or External-Storage) - FILTERS Tested: jam (linux32-LE), koala (linux64-LE), ostrich (linuxppc64-BE), tejeda (mac32-LE), linew (solaris-BE) --- bin/trace | 1 + release_docs/RELEASE.txt | 3 + src/H5Dio.c | 2 +- src/H5Dmpio.c | 66 +++-- src/H5Dpkg.h | 3 +- src/H5Dprivate.h | 2 + src/H5Pdxpl.c | 51 ++++ src/H5Ppublic.h | 14 + src/H5trace.c | 54 ++++ testpar/t_dset.c | 684 +++++++++++++++++++++++++++++++++++++++++++++++ testpar/testphdf5.c | 4 + testpar/testphdf5.h | 16 ++ 12 files changed, 871 insertions(+), 29 deletions(-) diff --git a/bin/trace b/bin/trace index a35e106..e9d1203 100755 --- a/bin/trace +++ b/bin/trace @@ -38,6 +38,7 @@ $Source = ""; "H5FD_mpio_chunk_opt_t" => "Dh", "H5D_mpio_actual_io_mode_t" => "Di", "H5D_layout_t" => "Dl", + "H5D_mpio_no_collective_cause_t" => "Dn", "H5D_mpio_actual_chunk_opt_mode_t" => "Do", "H5D_space_status_t" => "Ds", "H5FD_mpio_xfer_t" => "Dt", diff --git a/release_docs/RELEASE.txt b/release_docs/RELEASE.txt index a8818c9..328bba6 100644 --- a/release_docs/RELEASE.txt +++ b/release_docs/RELEASE.txt @@ -167,6 +167,9 @@ New Features Parallel Library: ----------------- + - Add H5Pget_mpio_no_collective_cause() function that retrive reasons + why the collective I/O was broken during read/write IO access. + (JKM - 2012/08/30 HDFFV-8143) - Special Collective IO (IO when some processes do not contribute to the IO) and Complex Derived Datatype MPI functionalities are no longer conditionally enabled in the library by configure.
