MPI_Cart_coords - Determines process coordinates in
Cartesian topology, given the rank in the group
SYNOPSIS
C:
#include <mpi.h>
int MPI_Cart_coords ( comm, rank, maxdims, coords )
MPI_Comm comm;
int rank;
int maxdims;
int *coords;
C++:
#include <mpi.h>
void Cartcomm::Get_coords(
int rank,
int maxdims,
int coords[]) const
Fortran:
INCLUDE "mpif.h" (or USE MPI)
INTEGER comm, rank, maxdims, coords(*),
ierror
CALL MPI_CART_COORDS(comm, rank, maxdims,
coords(*), 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 Standard.
DESCRIPTION
The MPI_Cart_coords routine determines process coordinates
in Cartesian topology, given the rank in the group. This
routine accepts the following parameters:
comm Specifies a communicator with Cartesian
structure (handle)
rank Specifies the rank of a process within the
group of comm (integer)
maxdims Specifies the length of vector coordinates
coords Returns an output integer array (of size
ndims from the MPI_Cart_create(3) routine)
that contains the Cartesian coordinates of
the specified process (integer)
ierror Specifies the return code value for
successful completion, which is in
MPI_SUCCESS. MPI_SUCCESS is defined in the
mpif.h file.
