Function Documentation

int main	(	int	argc,
		char **	argv
	)

Main function which selects the process to be a master or a worker based on MPI myid.

Parameters:

	argc	Number of arguments.
	argv	Pointer to the argument pointers.

Returns:

0 on success.

static int parse_args	(	int	argc,
		char *	argv[],
		struct test_params_s *	test_params_p
	)			[static]

Parse the command line arguments and set the test_params structure

Parameters:

	argc	Number of arguments.
	argv	Pointer to the argument pointers.
	test_params_p	Pointer to test_params.

Returns:

0 on success.

static int precalculate_results	(	struct test_params_s *	test_params_p,
		struct frag_preresult_s **	query_frag_preresult_matrix
	)			[static]

In order to help generate repeatable pseudo-random results for a given set of input parameters, the master precalculates how many results will be generated for each query.

Parameters:

	test_params_p	Pointer to test_params.
	query_frag_preresult_matrix	Pointer to the matrix of (query,frag) results.

Returns:

0 on success.

static int print_hints

(

struct test_params_s *

test_params_p

)

[static]

Get the hint information from the MPI_Info variable stored in the test_params and print it out.

Parameters:

test_params_p

Pointer to test_params.

Returns:

0 on success.

static void print_settings	(	struct test_params_s *	test_params_p,
		int	numprocs
	)			[static]

Print out the setting information for the application run.

Parameters:

	test_params_p	Pointer to test_params.
	numprocs	Number of processes used.

Returns:

0 on success.

static void print_usage

(

char *

exefile

)

[static]

Prints out the usage of the executable

Parameters:

exefile

Pointer to the name of the executable.
