This paper presents an evaluation of parallel performance of a computational fluiddynamics solver on PC-clusters. The solver uses unstructured grids and is parallelized bydomain decomposition using MPI as the communication library. The influence of nodeconfiguration and type of cluster network on the parallel performance is investigated fortypical applications from an aerospace design environment. The high performance networkbecomes significant when the system scales up. More important is the node configurationwhere memory bandwidth saturation limits the performance on dual nodes.
