Abstract

NuscaS is an object-oriented package designed at Czestochowa University of Technology to investigate thermomechanical phenomena using FEM modeling. Its functionality includes also implementation on clusters. This paper presents our experience in adaptation of the NuscaS system to the CLUSTERIX environment, which is a national grid infrastructure with 12 local Linux PC-clusters connected by the Polish Optical Network PIONIER. Using the MPICH-G2 middleware, the proposed solution allows for running tasks across several local clusters as meta-applications. The performance results of numerical experiments with FEM modeling of casting solidification confirm that CLUSTERIX can be an efficient platform for running numerical meta-applications. However, harnessing its computing power needs to take into account the hierarchical architecture of the infrastructure.
