Preface
It is a pleasure to announce that after the installation of the IBM Blue Gene/P at NIC/JSC in May 2009, as part of the Gauss Centre for Supercomputing (GCS) – linking together the three national supercomputing centres HLRS (Stuttgart), NIC/JSC (J¨ulich), and LRZ (Garching) – the next major step has been realized at HLRS with the installation of a new system, HERMIT, in October 2011. HERMIT is a large Cray XE-6 with a peak speed of more than 1 PFLOP/s. Based on the new AMD Interlagos chip, two sockets form a node, and HERMIT brings together 3,552 compute nodes with 113,664 cores, integrated into 38 water-cooled cabinets. Additionally, the system is tightly integrated with external servers for pre- and postprocessing to support complex workflows. The new system entered the Top500 list in November 2011 and ranked n
