Fastest Supercomputer in Europe Officially Released for Operation at Jülich Supercomputing Centre (JSC)

JUQUEEN Completes Final Configuration With 28 Racks, Delivering a Peak Performance of Almost 6 Petaflops

Berlin/Germany, February 28, 2013 – The most powerful supercomputer in Europe to date, HPC system JUQUEEN, has now officially been released for operation at GCS member Jülich Supercomputing Centre. JUQUEEN, which currently holds position 5 on the TOP500 list (11/2012), reached its final stage of configuration with the installation of the last four of 28 computer racks. Now, 458,752 compute cores boost the system’s performance to a peak of about 6 Petaflops (6 quadrillion floating point operations per second), a ratio not matched by any other HPC system in Europe.

JSC’s Queen of European Supercomputers was the first HPC system in Europe to pass the 5 Petaflops barrier with its configuration of 24 racks achieved in late 2012. JUQUEEN was first implemented at the Jülich Supercomputing Centre in May 2012 with initially 8 racks and was gradually expanded to its final configuration featuring 28 racks in early 2013. The IBM BlueGene/Q system is especially designed for compute intensive, highly scalable applications which can run in parallel on a very high number of compute cores. "JUQUEEN is targeted to tackle comprehensive and complex scientific questions, called Grand Challenges", explains Prof. Thomas Lippert, Director of JSC. "Projects from various scientific areas can profit from the system’s performance, e.g. in the areas of neuroscience, computational biology, energy, or climate research. Moreover, it enables complicated calculations in quantum physics, which were not possible before.“

The JSC flagship computer is not only a global key player in terms of system speed. With a performance/power ratio of approximately 2 Gigaflop/s per Watt, JUQUEEN holds 5th place on the current Green500 ranking, making the Jülich HPC system one of the most energy efficient supercomputers worldwide.

HPC System for National and European Science and Research Activities

As with the HPC systems of the other two members of the Gauss Centre for Supercomputing – High Performance Computing Center Stuttgart (HLRS) and Leibniz Supercomputing Centre Garching near Munich (LRZ) – computing time on JUQUEEN is granted to researchers in Germany and Europe by a comparative scientific peer review process.

About GCS:

The Gauss Centre for Supercomputing (GCS) combines the three national supercomputing centres HLRS (High Performance Computing Center Stuttgart), JSC (Jülich Supercomputing Centre), and LRZ (Leibniz Supercomputing Centre, Garching) into Germany’s Tier-0 Supercomputing institution. Concertedly, the three centres provide the largest and most powerful supercomputer infrastructure in Europe to serve a wide range of industrial and research activities in various disciplines. They also provide top-class training and education for the national as well as the European High Performance Computing (HPC) community. GCS is the German member of PRACE (Partnership for Advance Computing in Europe), an international non-profit association consisting of 25 member countries, whose representative organizations create a pan-European supercomputing infrastructure, providing access to computing and data management resources and services for largescale scientific and engineering applications at the highest performance level.

GCS is jointly funded by the German Federal Ministry of Education and Research and the federal states of Baden-Württemberg, Bavaria and North Rhine-Westphalia.

GCS has its headquarters in Berlin/Germany.
