The Leibniz Supercomputing Centre (LRZ) and the Bavarian Competence community for Technical and Scienti?c excessive functionality Computing (KONWIHR) put up within the current e-book result of numerical simulations facilitated through the excessive P- formance computing device method in Bavaria (HLRB II) in the final years. The papers have been awarded on the Fourth Joint HLRB and KONWIHR assessment and - sult Workshop in Garching on eighth and ninth December 2009, and have been chosen from all development studies of tasks that use the HLRB II. just like the workshop years in the past, the vast majority of the contributed papers belong to the realm of computational ?uid dynamics (CFD), condensed topic physics, astrophysics, chemistry, computing device sciences and high-energy physics. We notice a substantial raise of the person c- munity in a few parts: in comparison to 2007, the variety of papers elevated from 6 to twelve in condensed topic physics and from 2 to five in high-energy physics. Bio s- ences contributed just one paper in 2007, yet 4 papers in 2009. this means that the realm of program of supercomputers is constantly transforming into and getting into new ?elds of analysis. The 12 months 2007 observed significant occasions of specific significance for the LRZ. First, after a considerable improve with dual-core processors the SGI Altix 4700 superc- puter reached a height functionality of greater than sixty two Tera?op/s. And moment, the n- pro?t association Gauss Centre for Supercomputing e. V. (GCS) used to be based on April 13th.
