Function Documentation

int generate_rand_hist	(	int	myid,
		unsigned int *	seed_p,
		int	sequence_type,
		struct work_info_s *	work_info_p,
		struct mpe_events_s *	mpe_events_p,
		struct test_params_s *	test_params_p
	)

Based on the histogram information provided by either the query or database distributions, generate a sequence size.

Parameters:

	myid	MPI myid.
	seed_p	Seed to generate pseudo-random output.
	sequence_type	Either a QUERY or DATABASE type.
	work_info_p	Pointer to work information structure.
	mpe_events_p	Pointer to timing structure.
	test_params_p	Pointer to test_params.

Returns:

The sequence size, or negative values on error.

void print_hist_params	(	struct test_params_s *	test_params_p,
		int	sequence_type
	)

Prints out the histogram information from the test_params structure that has already been parsed from a file for either query or database distributions.

Parameters:

	test_params_p	Pointer to test_params.
	sequence_type	Either a QUERY or DATABASE type.

int read_hist_params	(	struct test_params_s *	test_params_p,
		int	sequence_type
	)

Reads in histogram information from a file for either query or database distributions.

Parameters:

	test_params_p	Pointer to test_params.
	sequence_type	Either a QUERY or DATABASE type.

Returns:

0 on success.
