Data Structures
struct	timer_data

Functions
void *	start_timer (MPI_Comm comm, char const *fmt,...)
	Starts a timer and returns a pointer to the timer data.
void	stop_timer (void *timer_)
	Stops the timer and prints the timing results.
void	init_grid (int comp_id, char const *grid_name, char const *grid_filename, int *cell_point_id, int *corner_point_id)
	Initializes grid data and registers it with YAC.

Function Documentation

init_grid()

void init_grid	(	int	comp_id,
		char const *	grid_name,
		char const *	grid_filename,
		int *	cell_point_id,
		int *	corner_point_id )

Initializes grid data and registers it with YAC.

Parameters

[in]	comp_id	The component ID.
[in]	grid_name	The name of the grid.
[in]	grid_filename	The filename of the grid.
[out]	cell_point_id	Pointer to the cell center point ID.
[out]	corner_point_id	Pointer to the corner point ID.

Remarks

Supports all grid files that can be read by yac_read_icon_grid_information_parallel

The grid file is read by and decomposed among all processes of the component communicator.

start_timer()

void * start_timer	(	MPI_Comm	comm,
		char const *	fmt,
			... )

Starts a timer and returns a pointer to the timer data.

Parameters

[in]	comm	The MPI communicator.
[in]	fmt	The format string for the timer label.
[in]	...	Additional arguments for the format string.

Returns

A pointer to the timer data.

Here is the caller graph for this function:

stop_timer()

void stop_timer

(

void *

timer

)

Stops the timer and prints the timing results.

Parameters

[in]

timer

A pointer to the timer data.

Remarks

This is a collective operation for all processes in the communicator used to start the timer.

The timing results are printed to stderr by the root process of the communicator.
