On Residual Smoothing in ILUM-type Preconditioning
Lutz Grosz
Abstract:
Incomplete block factorizations are used to construct
flexible preconditioners for iterative linear solvers. In practice
these approaches have shown to be very effective and rather
robust. Especially they are more suitable for parallel computer
architectures when comparing to classic ILU preconditioning. In
this paper we introduce residual smoothing into the
forward/backward substitution in order to compensate the element
dropping in the Schur complement.
