Object-oriented SPH-simulations with surface tension

Abstract

Today object-oriented software development is well established in industry and research and has replaced procedural techniques. Nevertheless there is a lack of integration of object-oriented concepts in parallel scientific applications and the underlying parallelization libraries. To benefit from advantages of object-oriented programming like easy configurability and good extensibility, we implemented a framework for SPH simulations to support the ongoing development of the SPH method. We used the high performance systems at HLRS during the last year to test our object-oriented approach and the influences of several configurations on the runtimes and speedup on different machines. We integrated parallel I/O and surface tension in our framework and show first results. The implementation of object-oriented parallel I/O improved the performance significantly. The next step is to optimize and advance the surface tension model.
