Abstract

The paper develops the Displacement Decomposition technique used already in [1] for parallelization of the Preconditioned Conjugate Gradient method. This time, the solution of very large problems is tackled. We present our experience with (PVM-)parallel solution of a huge finite element model arising from geomechanical practice on usual hardware and describe various facets of the optimizing process, leading to a tenfold improvement of the solution time. Special effects of parallelizing I/O-constrained programs are also addressed.
