Beschreibung
Zusammenfassung:	New parallel Normalized Explicit Preconditioned Conjugate Gradient-type methods are introduced for solving finite element systems on distributed memory MIMD systems. The performance and applicability of the proposed methods implemented in message passing interface, is discussed by solving a characteristic two dimensional boundary value problem and numerical results are given.
