Performance Modeling of Parallel FEM Computations on Clusters

ParallelNuscaS is an object-oriented package for the parallel finite element modeling, developed at Czestochowa University of Technology. This paper is devoted to modeling the performance of the package on PC-clusters. Such modeling allows for analyzing and predicting the performance of this complex scientific application on different computing platforms. Because both uniprocessor and SMP nodes are considered, we investigate not only the message-passing model of parallel programming, but also the hybrid model, which is a mixture of multithreading inside SMP nodes and message passing between them.
