The code is easily transferable. The numerics remained all vectorized, enabling a vector as well as a parallel run on multi- ple computer systems. The implicit solver works blockwise. This technique saves memory in case of a sequential run and enables high speed-ups in case of a parallel run. Parallelization remains coarse grain for any number of nodes that are introduced. INTRODUCTION Present research and development in aerospace science disclose the strong need for more computing power and - not least - memory. Traditional super vector computers more and mor
