communicator
SYNOPSIS
C:
#include <mpi.h>
int MPI_Comm_rank ( comm, rank )
MPI_Comm comm;
int *rank;
C++:
#include <mpi.h>
int Comm::Get_rank() const
Fortran:
INCLUDE "mpif.h" (or USE MPI)
INTEGER comm, rank, ierror
CALL MPI_COMM_RANK(comm, rank, 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
