JSC currently hosts the fastest supercomputer in Europe, code-named JUQUEEN. With a peak performance of 5.9 Petaflops, JUQUEEN was also the first HPC system in Europe to pass the 5 Petaflops barrier (quadrillions of calculations per second). It holds 7th place on the world-wide listing (TOP500, June 2013).

JUQUEEN is an IBM BlueGene/Q system based on the IBM POWER architecture hosting 458,752 compute core. The 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 amongst the most energy-efficient supercomputers in the world. With a performance/power ratio of approximately 2 Gigaflop/s per Watt, JUQUEEN provides a fivefold improvement in energy efficiency compared to its predecessor JUGENE thanks to a direct water cooling system that takes away heat directly from the processors.
