MPI_Cart_rank function

Determines process rank in communicator given Cartesian location.

Syntax

int MPIAPI MPI_Cart_rank(
        MPI_Comm comm,
  _In_  int      *coords,
  _Out_ int      *rank
);

comm
Communicator with cartesian structure.
coords [in]
Integer array (of size ndims, the number of dimensions of the Cartesian topology associated with comm) specifying the cartesian coordinates of a process.
rank [out]
Rank of specified process.

Returns MPI_SUCCESS on success. Otherwise, the return value is an error code.

In Fortran, the return value is stored in the IERROR parameter.

    MPI_CART_RANK(COMM, COORDS, RANK, IERROR)
        INTEGER COMM, COORDS(*), RANK, IERROR
