NAME
MPI_Dims_create - Creates a division of processors in a cartesian gridSYNOPSIS
#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.
