MPI_Cart_coords function

Determines process coords in cartesian topology given rank in group.

Syntax

int MPIAPI MPI_Cart_coords(
   MPI_Comm               comm,
   int                    rank,
   int                    maxdims,
   _Out_cap_(maxdims) int *coords
);

Parameters

• comm
  Communicator with cartesian structure.

• rank
  Rank of a process within group of comm.

• maxdims
  Length of vector coords in the calling program.

• coords
  Integer array (of size maxdims) containing the Cartesian coordinates of specified process.

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.
