Navigation and service


In preparation for the upcoming replacement of the JUROPA HPC cluster, a prototype system called JUROPA-3 has recently been installed and successfully accepted at JSC. JUROPA-3 is the outcome of a cooperation between JSC, ParTec Cluster Competence Center GmbH, and T-Platforms. The purpose of the cooperation is to study possible solutions for fundamental questions in large-scale cluster computing. Topics like application check-point/restart, end-to-end data integrity, network topology, failure prediction and energy efficiency will be addressed. JUROPA-3 will serve as a testbed for these investigations.

In addition, a small sub-partition of JUROPA-3 will be used as a platform for long-running application codes solving static non-linear structural mechanics problems with high memory demands. This partition, financed by ZEA-1 (Engineering and Technology) at Jülich, will be hosted by JSC.

JUROPA-3 comprises 60 compute nodes, each equipped with two Intel Xeon E5-2650 CPUs (Sandy Bridge-EP) providing a total of 960 processor cores with a peak performance of 15.3 teraflops. In addition, eight compute nodes are each enhanced with either two NVIDIA Tesla K20X GPUs or two Intel Xeon Phi 5110P co-processors. The co-processors amount to an extra performance of 18.5 teraflops peak.
