* VFD ctl feature (#981)jhendersonHDF2021-09-231-19/+71
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * Added "ctl" callback to the VFD interface, and the associated H5FDctl() and H5FD_ctl() calls. Modified the MPIO VFD accordingly -- specifically: Added ctl() call with op-code support to expose rank, size, and communicator. Modified H5FD_mpi_get_rank(), H5FD_mpi_get_size(), and H5FD_mpi_get_comm() to use the new ctl() callback. In passing removed the const qualifier from the file parameter of these functions, as the file parameter of the ctl callback is not const. Deleted the old H5FD__mpio_mpi_rank(), H5FD__mpio_mpi_size(), and H5FD__mpio_communicator() calls from the MPIO VFD. Deleted H5FD_class_mpi_t from H5FDprivate.h, and modified the MPIO VFD accordingly. Note that all VFDs now use H5FD_class_t, with no special class for VFDs that that support MPI. Some minor touch ups to the Neil's selection I/O mods in passing. Tested serial and parallel, debug and production on charis and jelly. * Reserve a range of VFD "ctl" opcodes for library and experimental usage * Add "ctl" callbacks to passthrough VFDs * Add RELEASE.txt entry for "ctl" callback * Use H5FDopen with H5F_ACC_RDWR flag instead of H5F_ACC_TRUNC in vfd test * Remove handling of passthrough "ctl" flag from multi VFD * Move logic for testing H5FD_CTL__TEST_OPCODE into a testing VFD Revise description of "ctl" callback in RELEASE.txt Remove unused H5FD_CTL__NUM_OPCODES definition Fix some warnings in multi VFD Co-authored-by: mainzer <mainzer#hdfgroup.org>

* | Checkin of fix for CGNS bugmainzer2017-04-061-0/+39
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | (https://jira.hdfgroup.org/browse/HDFFV-10055). Briefly, in H5C_collective_write() in H5Cmpio.c, the metadata cache attempts to perform a collective write of metadata cache entries. This worked fine as long as all processes had at least one entry to write. However, when the process has no entries, the function tries to participate in the collective write by calling MPI_File_set_view(), MPI_File_write_all() and then MPI_File_set_view() again, to match the calls in H5FD_mpio_write(). After pull request 183, the CGNS test benchmark_hdf5 started failing. On investigation, I determined that the failure occurred in the first call to MPI_File_set_view() in the "no data to write" path through H5C_collective_write(). Note that pull request 183 did not create the problem, it only exposed it. The bug can be observed after pull request 182 if one executes the CGNS progam src/ptests/benchmark_hdf5 with 90 processes. The problem appears to have been that the calls to MPI_File_set_view() in H5C_collective_write() and H5FD_mpio_write() were using different values for the info parameter. I patched the problem by adding a MPI specific VFD call allowing me to get the MPI_Info used in H5FD_mpio_write() for use in MPI_File_set_view() calls in H5C_collective_write(). Tested serial & parallel, debug & production on Jelly.

* [svn-r8731] Purpose:Quincey Koziol2004-06-231-4/+0
| | | | | | | | | | | | | | | 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. Platforms tested: FreeBSD 4.10 (sleipnir) w/gcc34 h5committest

* [svn-r8126] Purpose:Quincey Koziol2004-01-311-0/+538
Bug fix/optimization Description: Address slowdown in MPI-I/O file metadata operations that was introduced mid-stream. We now _require_ a POSIX compliant parallel file system for the MPI-I/O file driver (as well as for the MPI-POSIX file driver). Also optimized file open operation when the file is being created by reducing the number of collective & syncronizing calls. Additionally, refactor the MPI routines into a common place, eliminating duplicated code. Platforms tested: FreeBSD 4.9 (sleipnir) w/parallel h5committest
