Member Function/Subroutine Documentation

 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.
