Function Documentation

cs_blas_cuda_asum()

double cs_blas_cuda_asum	(	cs_lnum_t	n,
		const cs_real_t	x[]
	)

Return the absolute sum of vector values using CUDA.

Parameters

[in]	n	size of array x
[in]	x	array of floating-point values (on device)

Returns

sum of absolute array values

cs_blas_cuda_axpy()

void cs_blas_cuda_axpy	(	cs_lnum_t	n,
		const cs_real_t *	alpha,
		const cs_real_t *	x,
		cs_real_t *	y
	)

cs_blas_cuda_dot()

double cs_blas_cuda_dot	(	cs_lnum_t	n,
		const cs_real_t	x[],
		const cs_real_t	y[]
	)

Return the dot product of 2 vectors: x.y using CUDA.

Parameters

[in]	n	size of arrays x and y
[in]	x	array of floating-point values (on device)
[in]	y	array of floating-point values (on device)

Returns

dot product

cs_blas_cuda_finalize()

void cs_blas_cuda_finalize

(

void

)

Finalize CUDA BLAS API.

This frees resources such as the cuBLAS handle, if used.

cs_blas_cuda_scal()

void cs_blas_cuda_scal	(	cs_lnum_t	n,
		const cs_real_t *	alpha,
		cs_real_t *	x
	)
