PARALLEL FINITE ELEMENT APPROXIMATE INVERSE PRECONDITIONING ON SYMMETRIC MULTIPROCESSOR SYSTEMS

摘要

Parallel normalized preconditioned conjugate gradient type methods based on normalized approximate finite element inverse matrix techniques are investigated for the efficient solution of sparse linear systems. Application of the proposed methods on a three dimensional boundary value problems is discussed and numerical results are given. The parallel implementation of the normalized preconditioned conjugate gradient - type methods is also discussed and speedups are presented.
