Preface
Again, the last year has been very successful for high performance computing in Baden-Württemberg and beyond. The NEC SX-8 vector supercomputer is highly utilized and has been very successfully used by many scientific projects. In February 2007, the new “Landes-Höchstleistungsrechner HP XC4000” has been inaugurated at the SSC in Karlsruhe. This massively parallel high performance system complex, built from hundreds of Intel Itanium processors and more than three thousand AMD Opteron cores, has helped in doing additional science on a very high level. Nevertheless, the time has already come to start thinking about the next follow-up system in future. The discussions and plans on all scientific, advisory, and political levels to realize an even larger “European Supercomputer” in Germany, where the hardware costs alone wi
