MPI_File_write_at_all_begin - Begin a split collective
write using explicit offset
SYNOPSIS
C:
#include <mpi.h>
int MPI_File_write_at_all_begin( fh, offset, buf,
count, datatype )
MPI_File fh;
MPI_Offset offset;
void *buf;
int count;
MPI_Datatype datatype;
Fortran:
INCLUDE "mpif.h" (or USE MPI)
<type> buf(*)
INTEGER fh, count, datatype, ierror
INTEGER(KIND=MPI_OFFSET_KIND) offset
CALL MPI_FILE_WRITE_AT_ALL_BEGIN(fh, offset, buf,
count, datatype, ierror)
STANDARDS
This release implements the MPI 2.0 standard, as
documented by the MPI Forum in the July 1997 release of
MPI: A Message Passing Interface Standard.
DESCRIPTION
MPI_File_write_at_all_begin begins a split collective
write using explicit offset. This routine accepts the
following parameters:
fh file handle (handle)
offset file offset (nonnegative integer)
buf initial address of buffer (choice)
count number of elements in buffer (nonnegative
integer)
datatype datatype of each buffer element (handle)
Fortran Programs
All MPI routines in Fortran (except for MPI_WTIME(3F) and
MPI_WTICK(3F)) have the additional argument ierror at the
end of the argument list. ierror is an integer and has
In Fortran, MPI routines are subroutines, and are invoked
with the CALL statement.
All MPI objects (such as MPI_Datatype(3) and MPI_Comm(3))
are of type INTEGER in Fortran.
