JURECA Booster to Be Decommissioned in October

JSC will decommission the JURECA Booster at the end of October 2022. In November 2021, 400 nodes were already taken offline to provide an additional power budget for JURECA-DC. The remaining 1,240 nodes will stay available until the end of October. Because the JURECA Booster is accessed via JURECA-DC logins, the access pattern will not change. Users who currently rely on the JURECA Booster should migrate their workloads to other systems like JURECA-DC or the JUWELS Booster, given the additional performance these platforms provide.

The JURECA Booster entered production in 2017 and extended the existing JURECA Cluster supercomputer to create the first production-ready modular supercomputer, a result of the DEEP projects and prototypes that paved the way for the development of the Modular Supercomputing Architecture (MSA). At the time, JURECA was the first system to combine high-speed NVIDIA Mellanox InfiniBand and Intel OmniPath interconnects via bridging on the hardware and software level. The deployment involved a concerted effort by the participating partners, namely Dell, Intel, JSC, ParTec, and T-Platforms. JURECA was the first modular supercomputer to be included on the Top500 list. In November 2017, it was ranked 30th with the Linpack benchmark running across both the JURECA Cluster, installed in 2015 with 2.3 petaflops, and the JURECA Booster, with a peak performance of 5 petaflops based on Intel Knights Landing processors.
