subroutine spariterprecond::pardiagprec	(	double precision, dimension(*)	u,
		double precision, dimension(*)	v,
		integer, dimension(*)	ipar
	)

Parallel diagonal preconditioning.

subroutine spariterprecond::parilu0

(

type (matrix_t)

Matrix)

This routine is used to perform ILU(0) preconditioning setup Incomplete LU factorization is saved to Matrix % ILUValues. Diagonal entries are inverted.

subroutine spariterprecond::parlprec	(	double precision, dimension(*)	u,
		double precision, dimension(*)	v,
		integer, dimension(*)	ipar
	)

This routines performs a forward solve for ILU factorization, i.e. solves Lu = v. Diagonal values of U must be already inverted.

subroutine spariterprecond::parluprec	(	double precision, dimension(*)	u,
		double precision, dimension(*)	v,
		integer, dimension(*)	ipar
	)

This routines performs a forward and backward solve for ILU factorization, i.e. solves (LU)u = v. Diagonal values of U must be already inverted.

Here is the call graph for this function:

subroutine spariterprecond::paruprec	(	double precision, dimension(*)	u,
		double precision, dimension(*)	v,
		integer, dimension(*)	ipar
	)

This routines performs backward solve for ILU factorization, i.e. solves Uu = v. Diagonal values of U must be already inverted.
