Libraries and Methods for Parallel Particle Simulations

We used the high performance systems at HLRS in the last year for two different works. One was the hybrid implementation and optimization of ParaSPH a library for the parallel computation of particle simulations. We give details of the parallelization of ParaSPH for hybrid architectures (clustered SMPs) using MPI and OpenMP and discuss performance results for single node and speedups of the code on the Opteron Cluster and the NEC SX-6. The other work we present is the enhancement of an object-oriented framework for messages passing called TPO++ to support object-oriented parallel I/O.
