Maps process to Cartesian topology information
Synopsis
int MPIX_Nodecart_map(MPI_Comm comm, int ndims, const int dims[],
const int periods[], int *newrank)
Input Parameters
- comm
- input communicator (handle)
- ndims
- number of dimensions of Cartesian structure (integer)
- dims
- integer array of size ndims specifying the number of processes in
each coordinate direction
- periods
- logical array of size ndims specifying the periodicity
specification in each coordinate direction
Output Parameters
- newrank
- reordered rank of the calling process; MPI_UNDEFINED if
calling process does not belong to grid (integer)
