cs_matrix_variant_tuned()

cs_matrix_variant_t* cs_matrix_variant_tuned	(	const cs_matrix_t *	m,
		int	verbosity,
		int	n_measure,
		double	t_measure
	)

Build a matrix variant tuned matrix.vector product operations.

The variant may later be applied to matrices of the same type and fill type.

In presence of supported accelerated devices, an array of 3 variants is returned; the second one applies to the host only, the third one to the device only.

Parameters

[in]	m	associated matrix
[in]	verbosity	verbosity level
[in]	n_measure	minimum number of measuring runs
[in]	t_measure	minimum measure time

Returns

pointer to tuning results structure
