Detailed Description

A tag for incomplete LU factorization with threshold (ILUT)

Definition at line 45 of file ilut.hpp.

Constructor & Destructor Documentation

viennacl::linalg::ilut_tag::ilut_tag	(	unsigned int	entries_per_row = `20`,
		double	drop_tolerance = `1e-4`,
		bool	with_level_scheduling = `false`
	)

inline

The constructor.

Parameters

entries_per_row	Number of nonzero entries per row in L and U. Note that L and U are stored in a single matrix, thus there are 2*entries_per_row in total.
drop_tolerance	The drop tolerance for ILUT
with_level_scheduling	Flag for enabling level scheduling on GPUs.
