High Performance Computing in Science and Engineering 99

Prof. Dr. Egon Krause Aerodynamisches Institut, RWTH Aachen Wiillnerstr. 5 u. 7, D-52062 Aachen Prof. Dr. Willi Jager Interdisziplinares Zentrum fiir Wissenschaftliches Rechnen Universitat Heidelberg 1m Neuenheimer Feld 368, D-69120 Heidelberg High Performance Computing is progressing as a discipline providing im- portant tools for research and development in science and industry. The High- Performance Computing Center Stuttgart (HLRS) is not only providing the facilities, hard- and software for a growing community of researchers and developers, but it also promotes the know-how to use supercomputers effi- ciently. Regular exchange of information, of ideas and methods is essential in improving the proper use of the facilities,and their performance as well as the application of algorithms and of simulation techniques. A Second Result and Review Workshop on High-Performance Computing in Science and Engineering, (October 4 -6,1999) was organized by the HLRS in order to give an overview of the scientific work carried out during the past year and to demonstrate the state of the art in the various fields. In 1998 the Land Baden-Wiirttemberg decided to extend the responsibilities of the Steering Committee of the HLRS and therewith also the rules of access to its Scientific Supercomputing Center (SSC) Karlsruhe. That center was recently upgraded with the IBM RS 6000 SP, thereby significantly increasing the attractivity of the two centers, since the joint portfolio of computer- architectures now covers most of the application-profile of their users.
