Parameters

comm
Type: System..::.Int32
Existing communicator from which the new communicator will be created.
ndims
Type: System..::.Int32
Number of dimensions for Cartesian communicator's grid to have.
dims
Type: System..::.Int32 *
Array to specify sizes in each dimension.
periods
Type: System..::.Int32 *
