From 2b629eaceb37a14a9e33dafa6a2a50765fd7d629 Mon Sep 17 00:00:00 2001 From: Bill Wendling Date: Tue, 18 Dec 2001 13:35:23 -0500 Subject: [svn-r4732] Purpose: Bug Fix Description: Committing the changes in the MPI/IO stuff so that parallel HDF5 will work on HP-UX. It seems that on HP-UX, the MPI_Status variable needs to be initialized to 0 for it to work (i.e., in some other MPI calls, if there's garbage in the MPI_Status variable, then it will barf). Solution: Initialized to 0. Platforms tested: HP-UX parallel, Linux. --- src/H5FDmpio.c | 6 +++--- 1 file changed, 3 insertions(+), 3 deletions(-) diff --git a/src/H5FDmpio.c b/src/H5FDmpio.c index 437d18f..0888924 100644 --- a/src/H5FDmpio.c +++ b/src/H5FDmpio.c @@ -1091,7 +1091,7 @@ H5FD_mpio_read(H5FD_t *_file, H5FD_mem_t UNUSED type, hid_t dxpl_id, haddr_t add const H5FD_mpio_dxpl_t *dx=NULL; H5FD_mpio_dxpl_t _dx; MPI_Offset mpi_off, mpi_disp; - MPI_Status mpi_stat; + MPI_Status mpi_stat = {0}; MPI_Datatype buf_type, file_type; int size_i, bytes_read, n; int use_types_this_time, used_types_last_time; @@ -1347,7 +1347,7 @@ H5FD_mpio_write(H5FD_t *_file, H5FD_mem_t UNUSED type, hid_t dxpl_id, haddr_t ad const H5FD_mpio_dxpl_t *dx=NULL; H5FD_mpio_dxpl_t _dx; MPI_Offset mpi_off, mpi_disp; - MPI_Status mpi_stat; + MPI_Status mpi_stat = {0}; MPI_Datatype buf_type, file_type; int size_i, bytes_written; int mpi_rank=-1; @@ -1552,7 +1552,7 @@ H5FD_mpio_flush(H5FD_t *_file) H5FD_mpio_t *file = (H5FD_mpio_t*)_file; int mpi_rank=-1; uint8_t byte=0; - MPI_Status mpi_stat; + MPI_Status mpi_stat = {0}; MPI_Offset mpi_off; FUNC_ENTER(H5FD_mpio_flush, FAIL); -- cgit v0.12
