Constructor & Destructor Documentation

CommGrid::CommGrid	(	MPI_Comm	world,
		int	nrowproc,
		int	ncolproc
	)

Create row and column communicators (must be collectively called) C syntax: int MPI_Comm_split(MPI_Comm comm, int color, int key, MPI_Comm *newcomm) C++ syntax: MPI::Intercomm MPI::Intercomm::Split(int color, int key) consts Semantics: Processes with the same color are in the same new communicator
