MPI_File_read_all_begin - Begin a split collective read
using individual file pointer
SYNOPSIS
C:
#include <mpi.h>
int MPI_File_read_all_begin( fh, buf, count, datatype )
MPI_File fh;
void *buf;
int count;
MPI_Datatype datatype;
Fortran:
INCLUDE "mpif.h" (or USE MPI)
<type> buf(*)
INTEGER fh, count, datatype, ierror
CALL MPI_FILE_READ_ALL_BEGIN(fh, 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_read_all_begin begins a split collective read
using an individual file pointer. This routine accepts
the following parameters:
fh file handle (handle)
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
the same meaning as the return value of the routine in C.
In Fortran, MPI routines are subroutines, and are invoked
with the CALL statement.
are of type INTEGER in Fortran.
