Public Member Functions
void	Isend (int rank, MPI_Comm comm)
	Non-blocking send to processor 'rank'. Returns immediately. Completion (as tested by MPI_Wait/Test) does not mean the message was received – it may be on its way or just buffered locally.

void	Issend (int rank, MPI_Comm comm)
	Non-blocking synchronous send to processor 'rank'. Returns immediately. Completion (MPI_Wait/Test) means that the message was received.

void	Recv (int rank, int size, MPI_Comm comm)
	Post-probe receive from processor 'rank' of message size 'size'.

void	RecvDrop (int rank, int size, MPI_Comm comm)
	Like Recv(), but throw away the message.

	VarMessage ()

void	Clear ()
	Clear the message and associated request.
