associated with a communicator
SYNOPSIS
C:
#include <mpi.h>
int MPI_Topo_test ( comm, top_type )
MPI_Comm comm;
int *top_type;
C++:
#include <mpi.h>
int Comm::Get_topo()
Fortran:
INCLUDE "mpif.h" (or USE MPI)
INTEGER comm, status, ierror,
CALL MPI_TOPO_TEST(comm, status, ierror)
STANDARDS
This release implements the MPI 1.2 standard, as
documented by the MPI Forum in the spring 1997 release of
