MPI_Dims_create
Creates a division of processors in a cartesian grid 
Synopsis
#include "mpi.h"
int MPI_Dims_create(nnodes, ndims, dims)
int  nnodes;
int  ndims;
int *dims;
Input Parameters
|  | nnodes | number of nodes in a grid (integer) 
 | 
|  | ndims | number of cartesian dimensions (integer) 
 | 
In/Out Parameter
- dims  
-  integer array of size  ndims specifying the number of nodes in each 
dimension  
Notes for Fortran
All MPI routines in Fortran (except for MPI_WTIME and MPI_WTICK) 
havean additional argument ierr at the end of the argument list.  
ierris an integer and has the same meaning as the return value of the 
routinein C.  In Fortran, MPI routines are subroutines, and are invoked with 
thecall statement.
All MPI objects (e.g., MPI_Datatype, MPI_Comm) are of type 
INTEGERin Fortran.
