Function Documentation

int check_irecv	(	int	myid,
		int	wait_status,
		int *	flag_p,
		MPI_Request *	req_p,
		int *	req_status_p,
		int	new_req_status,
		struct mpe_events_s *	mpe_events_p,
		struct test_params_s *	test_params_p
	)

Check irecv request, shared by both the master and workers. It depends heavily on check_isendrecv().

Parameters:

	myid	MPI myid.
	wait_status	Status of the master/worker processes.
	flag_p	Pointer to request completion.
	req_p	Pointer to MPI request.
	req_status_p	Pointer to current state of request.
	new_req_status	The next state for the request (if successful).
	mpe_events_p	Pointer to timing structure.
	test_params_p	Pointer to test_params.

Returns:

0 on success.

int check_isend	(	int	myid,
		int	wait_status,
		int *	flag_p,
		MPI_Request *	req_p,
		int *	req_status_p,
		int	new_req_status,
		struct mpe_events_s *	mpe_events_p,
		struct test_params_s *	test_params_p
	)

Check isend request, shared by both the master and workers. It depends heavily on check_isendrecv().

Parameters:

	myid	MPI myid.
	wait_status	Status of the master/worker processes.
	flag_p	Pointer to request completion.
	req_p	Pointer to MPI request.
	req_status_p	Pointer to current state of request.
	new_req_status	The next state for the request (if successful).
	mpe_events_p	Pointer to timing structure.
	test_params_p	Pointer to test_params.

Returns:

0 on success.

static int check_isendrecv	(	int	icomm_type,
		int	myid,
		int	wait_status,
		int *	flag_p,
		MPI_Request *	req_p,
		int *	req_status_p,
		int	new_req_status,
		struct mpe_events_s *	mpe_events_p,
		struct test_params_s *	test_params_p
	)			[static]

Check either an isend or irecv request to gauge progress. This function is called by check_irecv() and check_isend() functions.

Parameters:

	icomm_type	Either ISEND or IRECV.
	myid	MPI myid.
	wait_status	Status of the master/worker processes.
	flag_p	Pointer to request completion.
	req_p	Pointer to MPI request.
	req_status_p	Pointer to current state of request.
	new_req_status	The next state for the request (if successful).
	mpe_events_p	Pointer to timing structure.
	test_params_p	Pointer to test_params.

Returns:

0 on success.
