MPI_DIMS_CREATE(3)					    MPI_DIMS_CREATE(3)

NAME
     MPI_Dims_create - Creates a division of processors in a Cartesian grid

SYNOPSIS
     C:

	  #include <mpi.h>

	  int MPI_Dims_create(nnodes, ndims, dims)
	  int  nnodes;
	  int  ndims;
	  int *dims;

     C++:

	  #include <mpi.h>

	  void Compute_dims(
	  int		    nnodes,
	  int		    ndims,
	  int		    dims[])

     Fortran:

	  INCLUDE "mpif.h" (or USE MPI)

	  INTEGER nnodes, ndims, dims(*), ierror

	  CALL MPI_DIMS_CREATE(nnodes, ndims, dims(*),
	  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_Dims_create routine creates a division of processors in a
     Cartesian grid.  This routine accepts the following parameters:

     nnodes    Specifies the number of nodes in a grid (integer)

     ndims     Specifies the number of Cartesian dimensions (integer)

     dims      Returns an integer array of size ndims that specifies the
	       number of nodes in each dimension

     ierror    Specifies the return code value for successful completion,
	       which is in MPI_SUCCESS.	 MPI_SUCCESS is defined in the mpif.h
	       file.
