communications
SYNOPSIS
C:
#include <mpi.h>
int MPI_Testall( count, array_of_requests, flag,
array_of_statuses )
int count;
MPI_Request array_of_requests[];
int *flag;
MPI_Status *array_of_statuses;
C++:
#include <mpi.h>
static bool Request::Testall(
int count,
Request array_of_requests[])
Fortran:
INCLUDE "mpif.h" (or USE MPI)
LOGICAL flag
INTEGER count, array_of_requests(*),
array_of_statuses(MPI_STATUS_SIZE,*), ierror
CALL MPI_TESTALL(count, array_of_requests(*), flag,
array_of_statuses(MPI_STATUS_SIZE,*), ierror)
STANDARDS
This release implements the MPI 1.2 standard, as documented by the MPI
Forum in the spring 1997 release of MPI: A Message Passing Interface
