JUQUEEN: 5.9 petaflop per second

The high performance Computer JUQUEEN at Forschungszentrum Juelich is the first supercomputer in Europe to reach a maximum compute performance of 5.9 Petaflop/s – equating to almost 6 quadrillion operations per second. The system opens up new possibilities for research intensive grand projects and a wider spectrum of participating work groups.

With 458,752 compute cores, the new system reaches a peak performance of 5.9 Petaflop/s, which equates to approximately 100,000 PCs based on a current performance level. JUQUEEN is an IBM BlueGene/Q system based on the IBM POWER architecture. Supercomputers of this kind are among 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 efficienca compared to its predecessor JUGENE thanks to a direct water cooling system that takes away heat directly from the processors.

Prepared for major challenges

JUQUEEN is targeted to tackle comprehensive and complex scientific questions. The system can be used especially for compute intensive, highly scalable applications which can run in parallel on a very high number of compute cores. Various scientific areas can profit from the new raised performance such as neuroscience, computational biology or energy and climate research or quantum physics.

Behind the Jülich supercomputer is a BlueGene/Q system developed by IBM. Supercomputers of this type currently top the Green500 list of the most energy-efficient supercomputers at two gigaflops per watt.

Scientists out of Juelich have had early access to the IBM BlueGene/Q-Architecture within the Exascale Innovation Center (EIC), a joint project from IBM Research and Development and Forschungszentrum Juelich. This allowed them to adapt their applications in advance to a prototype system. JUQUEEN has already been used for comprehensive calculations in the areal of particle physics and phase changes in materials for storing data.

Furthermore, brain scientists in Juelich are using the new system to simulate activity in brain structures. JUQUEEN promises also new possibilities for the Human Brain Project with its objective to simulate the human brain.

Serving Science

JUQUEEN was equally financed by Federal and State funds.The new system will be accessible to researchers in Germany and the whole of Europe. Two thirds of the computing time will be given to researchers via two supercomputing cooperations: the Gauss Centre for Supercomputing (GCS), a cooperation of the three German national High Performance Compute Centers in Juelich, Garching und Stuttgart, and the European Research Infrastructure PRACE. The third part will be accessible to users of Forschungszentrum Juelich and the Juelich-Aachen Research Alliance (JARA).
