Forschungszentrum Jülich - Annual Report 2012

Forschungszentrum Jülich | Annual Report 201240 The supercomputers in the Jülich Supercomputing Centre (JSC) JUGENE/JUQUEEN Relative numbers according to users JUROPA The Jülich supercomputers are used extensively by users outside Forschungszentrum Jülich. Computing time is allocated by independent science committees. GCS: Gauss Centre for Supercomputing (association of the three national supercomputing centres JSC, HLRS and LRZ) NIC: John von Neumann Institute for Computing (national allocation body, funded by the three Helmholtz centres Forschungszentrum Jülich, DESY, GSI) GRS: German Research School for Simulation Sciences PRACE: Partnership for Advanced Computing in Europe (European HPC infrastructure) DECI: DEISA Extreme Computing Initiative DEISA: Distributed European Infrastructure for Supercomputing Applications (European HPC infrastructure, forerunner of PRACE) User statistics In 2012, 2.2 billionprocessor core hours were allocated on JUGENE/JUQUEEN, and almost 125 millionon JUROPA (with the JUROPA processors being more powerful than the JUGENE processors). Coveted computing time – overbooking factor JUGENE/JUQUEEN 2 JUROPA 5 In 2012, within the framework of the Partnership for Advanced Computing in Europe (PRACE Tier-0), 21 European projects were calculated on JUGENE/JUQUEEN. Most of the computing time – 48% – was assigned to basic physics research, followed by the research area of medicine and life sciences – 16%.

The Jülich Supercomputing Centre provides scientists and engineers at Forschungszentrum Jülich, universities and research institutions both in Germa- ny and throughout Europe, as well as companies in the commercial sector with access to computing capacity of the highest performance class, assisting them in solving highly complex prob- lems using simulation calculations. The John von Neumann Institute for Comput- ing is responsible for the scientific eval- uation of projects. Jülich’s new super- computer JUQUEEN was installed during the second half of 2012. It was the first supercomputer in Europe to achieve a peak performance of 5.9 petaflop/s. This means that Forschungszentrum Jülich is currently the best equipped partner in the Gauss Centre for Super- computing (GCS) and takes a leading position in the supercomputing infra- structure of both Germany and Europe.
