Preface

The Leibniz Supercomputing Centre (LRZ) and the Bavarian Competence Network for Technical and Scientific High Performance Computing (KONWIHR) publish in the present book results of numerical simulations facilitated by the High Performance Computer System in Bavaria (HLRB II) within the last two years. The papers were presented at the Fourth Joint HLRB and KONWIHR Review and Result Workshop in Garching on 8th and 9th December 2009, and were selected from all progress reports of projects that use the HLRB II. Similar to the workshop two years ago, the majority of the contributed papers belong to the area of computational fluid dynamics (CFD), condensed matter physics, astrophysics, chemistry, computer sciences and high-energy physics. We note a considerable increase of the user community in some areas: Compared to 2007, the number of papers i
