Function Documentation

mirml_membench_bandwidth()

mirkl_error_t * mirml_membench_bandwidth	(	int	test_number,
		mirml_membw_ctx_t *	ctx
	)

Function for the determination of memory bandwidth.

Parameters

[in]	test_number	Test number, valid values are in the range [1,MIRML_MEMBENCH_BANDWIDTH_MAXTEST]
[in,out]	ctx	Context. Can be used for fine tuning of testing by setting respective parameters. On output contains results.

Note

On input set the required fields of context structure to zero for using default settings.

mirml_membench_latency()

mirkl_error_t * mirml_membench_latency	(	mirkl_size_t	buf_size,
		mirml_memlat_ctx_t *	ctx
	)

Function for the determination of memory latency.

Parameters

[in]	buf_size	Size of the test buffer in bytes.
[in,out]	ctx	Context. Can be used for fine tuning of testing by setting respective parameters. On output contains results.

Note

On input set the required fields of context structure to zero for using default settings.
