[in]	exclude_diag	exclude diagonal if true,
[in]	sync	synchronize ghost cells if true
[in]	d_x	multipliying vector values (on device)
[out]	d_y	resulting vector (on device)

Matrix.vector product y = A.x with MSR matrix, scalar HIP version.

Parameters

[in]	matrix	pointer to matrix structure
[in]	exclude_diag	exclude diagonal if true,
[in]	sync	synchronize ghost cells if true
[in]	d_x	multipliying vector values (on device)
[out]	d_y	resulting vector (on device)

cs_matrix_spmv_hip_msr_b()

void cs_matrix_spmv_hip_msr_b	(	cs_matrix_t *	matrix,
		bool	exclude_diag,
		bool	sync,
		cs_real_t	d_x[],
		cs_real_t	d_y[]
	)

Matrix.vector product y = A.x with MSR matrix, block diagonal HIP version.

Parameters

[in]	matrix	pointer to matrix structure
[in]	exclude_diag	exclude diagonal if true,
[in]	sync	synchronize ghost cells if true
[in]	d_x	multipliying vector values (on device)
[out]	d_y	resulting vector (on device)

Matrix.vector product y = A.x with MSR matrix, block diagonal HIP version.

Parameters

[in]	matrix	pointer to matrix structure
[in]	exclude_diag	exclude diagonal if true,
[in]	sync	synchronize ghost cells if true
[in]	d_x	multipliying vector values (on device)

cs_matrix_spmv_hip_msr_bb_rocsparse()

void cs_matrix_spmv_hip_msr_bb_rocsparse	(	cs_matrix_t *	matrix,
		bool	exclude_diag,
		bool	sync,
		cs_real_t	d_x[],
		cs_real_t	d_y[]
	)

Matrix.vector product y = A.x with MSR matrix, block rocSPARSE version.

Remmark: this functions is available with older rocSPARSE versions not providing the generic API, because they assume dense matrixes are always in column-major order, while row-major is needed with interleaved blocks.

Parameters

[in]	matrix	pointer to matrix structure
[in]	exclude_diag	exclude diagonal if true,
[in]	sync	synchronize ghost cells if true
[in]	d_x	multipliying vector values (on device)
[out]	d_y	resulting vector (on device)

		bool	exclude_diag,
		bool	sync,
		cs_real_t	d_x[],
		cs_real_t	d_y[]
	)

Matrix.vector product y = A.x with MSR matrix, scalar HIP version.

Parameters

[in]	matrix	pointer to matrix structure
[in]	exclude_diag	exclude diagonal if true,
[in]	sync	synchronize ghost cells if true
[in]	d_x	multipliying vector values (on device)
[out]	d_y	resulting vector (on device)
