Detailed Description

Direct blocking sending of messages without any intermediate buffer.

The blocking synchronous send-operation returns only when the receiver has completely received the message.

Functions
int	MOC_Ssend (void *buf, int count, MOC_Datatype datatype, int dest, int tag, MOC_Comm comm)
	Performs a blocking synchronous mode send operation.

Function Documentation

int MOC_Ssend	(	void *	buf,
		int	count,
		MOC_Datatype	datatype,
		int	dest,
		int	tag,
		MOC_Comm	comm
	)

Performs a blocking synchronous mode send operation.

Note:

This routine blocks until the message is received.

Parameters:

	buf	in Pointer to buffer where data is stored
	count	in Number of elements to be send (not equal to actual byte-value)
	datatype	in Type of elements to be send
	dest	in Rank of receiving process
	tag	in Tag of message
	comm	in communicator of message

Return values:

	MOC_SUCCESS	No error; MPI routine completed successfully.
