Libraries and Methods for Parallel Particle Simulations

  • Conference paper
High Performance Computing in Science and Engineering’ 05

  • 687 Accesses

Summary

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.

The range of applications using our libraries and methods is extended continuously. At present it covers many different astrophysical phenomena, basically accretion procedures, impact simulations, the simulation of brittle material and the simulation of separated two phase flows, for example the injection of diesel jets. Recently we work on a solution to simulate granular media with SPH.

This project is funded by the DFG within SFB 382: Verfahren und Algorithmen zur Simulation physikalischer Prozesse auf Höchstleistungsrechnern (Methods and algorithms to simulate physical processes on supercomputers).
