MPI_Dims_create
Creates a division of processors in a cartesian grid
Synopsis
#include "mpi.h"
int MPI_Dims_create(
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) have
an additional argument ierr at the end of the argument list. ierr
is an integer and has the same meaning as the return value of the routine
in C. In Fortran, MPI routines are subroutines, and are invoked with the
call statement.
All MPI objects (e.g., MPI_Datatype, MPI_Comm) are of type INTEGER
in Fortran.
