Function Documentation

int custom_MPE_Log_event	(	int	event,
		int	data,
		char *	string,
		struct mpe_events_s *	mpe_events
	)

A set of events are defined by another function. Using the event numbers, the correct timing procedure is done here. Start or stop timers and add to profiling information.

Parameters:

	event	Event number to process.
	data	If MPE is used, this int is logged.
	string	If MPE is used, this string is logged.
	mpe_events_p	Pointer to timing structure.

Returns:

0 on success.

int init_mpe_events

(

struct mpe_events_s *

mpe_events

)

If MPE is used, this function defines the event numbers with the MPE_Log_get_event_number() function. Otherwise, the event numbers are predefined.

Parameters:

mpe_events_p

Pointer to timing structure.

Returns:

0 on success.

void print_timing	(	int	myid,
		struct mpe_events_s *	mpe_events
	)

Print the timing information for the mpe_events structure. This is generally used for debugging.

Parameters:

	myid	MPI myid.
	mpe_events_p	Pointer to timing structure.

int timing_reduce	(	int	myid,
		int	numprocs,
		struct mpe_events_s *	mpe_events
	)

All MPE information and timing information is stored in the mpe_events structure. The timings are reduced to the master and are printed by the master.

Parameters:

	myid	MPI myid.
	numprocs	Number of processes used.
	mpe_events_p	Pointer to timing structure.

Returns:

0 on success.
