Function Documentation

cpucblk_zcfillin()

int cpucblk_zcfillin	(	pastix_coefside_t	side,
		const SolverMatrix *	solvmtx,
		const pastix_bcsc_t *	bcsc,
		pastix_int_t	itercblk
	)

Initialize the coeftab structure from the internal bcsc.

Parameters

[in]	side	Define which side of the matrix must be initialized. PastixLCoef if lower part only PastixUCoef if upper part only PastixLUCoef if both sides.
[in]	solvmtx	PaStiX structure to store numerical data and flags
[in]	bcsc	The internal bcsc structure that hold the graph with permutation stored by cblk.
[in]	itercblk	The index of the cblk to fill in both bcsc and solvmtx structures.

Returns

0 on success, 1 in case of overflow during initialization.

cpucblk_zcinit()

void cpucblk_zcinit	(	pastix_coefside_t	side,
		const SolverMatrix *	solvmtx,
		const pastix_bcsc_t *	bcsc,
		pastix_int_t	itercblk,
		const char *	directory
	)

Fully initialize a single mixed-precision cblk.

The cblk is allocated, intialized from the bcsc, and compressed if necessary.

Parameters

[in]	side	Define which side of the matrix must be initialized. PastixLCoef if lower part only PastixUCoef if upper part only PastixLUCoef if both sides.
[in]	solvmtx	The solver matrix data structure.
[in]	bcsc	The internal block CSC structure to fill-in the matrix.
[in]	itercblk	The index of the cblk to initialize.
[in,out]	directory	The pointer to the temporary directory where to store the output files. Used only if PASTIX_DEBUG_DUMP_COEFTAB is defined.

Try to compress the cblk if needs to be compressed
