C-45 3D PARALLEL ELASTIC WAVE MODELING - SCALABILITY ANALYSIS FOR (BEOWULF) CLUSTERS Abstract 1 A scalability analysis of the discretisized elastic wave equation shows that the efficiency of its parallel solution can be kept constant with a strip or 1D decomposition scheme by linearly increasing the problem size in one dimension with the number of processors. In an experiment we verify that this is even true for a Beowulf cluster with a slow network. Introduction Generally elastic wave modeling requires considerable computational resources because of the size of real problems. It appears that computational problems often possess a large degree
