The lectures will be presented by Dr.-Ing. Thomas Boenisch, head of the Project User Accounting and Management Department at HLRS. His research interests include parallel algorithms for CFD problems, benchmarking for high performance computing systems and high performance I/O. Thomas Boenisch was among the developers of a parallel algorithm for non-equilibrium re-entry flows in 3D that what used to model the prospective X-38 re-entry vehicle that was ported to several different high performance computing systems including NEX SX and Cray T3 families.
