Function Documentation

coeftab_dmemory_lr()

void coeftab_dmemory_lr	(	const SolverMatrix *	solvmtx,
		const pastix_int_t *	iparm,
		pastix_fixdbl_t *	dparm
	)

Compute the memory gain of the low-rank form over the full-rank form for the entire matrix.

This function returns the memory gain in bytes for the full matrix when column blocks are stored in low-rank format compared to a full rank storage.

Parameters

[in]	solvmtx	The solver matrix of the problem.
[in]	iparm	The integer parameter array
[in,out]	dparm	The double parameter array which is going to be updated.

coeftab_dmemory_fr()

void coeftab_dmemory_fr	(	const SolverMatrix *	solvmtx,
		const pastix_int_t *	iparm,
		pastix_fixdbl_t *	dparm
	)

Compute the memory usage of the full-rank form for the entire matrix.

This function returns the memory usage in bytes for the full matrix when column blocks are stored in full-rank format.

Parameters

[in]	solvmtx	The solver matrix of the problem.
[in,out]	dparm	The double parameter array which is going to be updated.
[in]	iparm	The integer parameter array
