Title: New Results on Parallel ILU Preconditioners

Submitter/s: Wayne Joubert, Los Alamos National Laboratory

Abstract: In this talk we present results on the use of ILU preconditioners
on large scale distributed memory parallel computers.  We give theoretical 
and experimental results on the performance of ILU with various parallel
orderings on parallel computers.  We also present a new fully parallel
global ILU implementation with natural ordering for structured grids
which scales well on large parallel computers.
