Function Documentation

HICMA_zgytlr_Tile()

int HICMA_zgytlr_Tile	(	MORSE_enum	uplo,
		MORSE_desc_t *	AUV,
		MORSE_desc_t *	AD,
		MORSE_desc_t *	Ark,
		unsigned long long int	seed,
		int	maxrank,
		double	tol,
		int	compress_diag,
		MORSE_desc_t *	Dense
	)

HICMA_zgytlr_Tile - Generate a random matrix by tiles. Operates on matrices stored by tiles. All matrices are passed through descriptors. All dimensions are taken from the descriptors.

HICMA_zgytlr_Tile - Generate matrix by tiles.

Parameters

[in]	uplo	Which part of matrix will be generated.
[in]	M	The number of rows of A.
[in]	N	The order of the matrix A. N >= 0.
[out]	AUV	On exit, U and V factors.
[out]	AD	On exit, diagonal tiles.
[out]	Ark	On exit, rank for each tile.
[in]	LDA	The leading dimension of the array A. LDA >= max(1,M).
[in]	seed	The seed used in the random generation.
[in]	maxrank	The limit for ranks.
[in]	tol	Threshold used in approximation.

Returns

Return values

MORSE_SUCCESS	successful exit
<0	if -i, the i-th argument had an illegal value

HICMA_zgytlr_Tile_Async()

int HICMA_zgytlr_Tile_Async	(	MORSE_enum	uplo,
		MORSE_desc_t *	AUV,
		MORSE_desc_t *	AD,
		MORSE_desc_t *	Ark,
		unsigned long long int	seed,
		int	maxrank,
		double	tol,
		int	compress_diag,
		MORSE_desc_t *	Dense,
		MORSE_sequence_t *	sequence,
		MORSE_request_t *	request
	)

HICMA_zgytlr_Tile_Async - Generate a random matrix by tiles. Non-blocking equivalent of HICMA_zgytlr_Tile(). May return before the computation is finished. Allows for pipelining of operations at runtime.

Parameters

[in]	sequence	Identifies the sequence of function calls that this call belongs to (for completion checks and exception handling purposes).
[out]	request	Identifies this function call (for exception handling purposes).
