MPI_Dims_create function
Creates a division of processors in a cartesian grid.
Syntax
int MPIAPI MPI_Dims_create(
int nnodes,
int ndims,
_Inout_count_(ndims) int *dims
);
Parameters
nnodes
Number of nodes in a grid.ndims
Number of cartesian dimensions.dims
Integer array of size ndims specifying the number of nodes in each dimension. A value of 0 indicates that MPI_Dims_create should fill in a suitable value.
Return value
Returns MPI_SUCCESS on success. Otherwise, the return value is an error code.
In Fortran, the return value is stored in the IERROR parameter.
