Abstract: Abstract A major goal of the Sonderforschungsbereich 382 is the development of different particle methods for solving physical problems. In this paper, we present two different implementations of parallel Smoothed Particle Hydrodynamics codes and a newly developed method called Finite Mass Methode. We follow up with the results of some test simulations which show the pros and cons of the different approaches. We talk about our experiences with these codes and conclusions for parallelization in general. Our recent work concentrated on object-oriented physical codes and runtime systems. The newly established particle method called Finite Mass Method (FMM), which got developed within the SFB 382 was ported to C++, and parallelized using MPI-1.1. The experiences made with this code led to an object- oriented parallel runtime system, based on message passing and threads. Finally we describe our proposed solutions for higher-level programming abstractions, including design patterns and application-domain specific libraries. Based on this work we currently develop an object-oriented prototype of a QMC simulation.
