JUWELS Cluster and Booster: Exascale Pathfinder with Modular Supercomputing Architecture at Juelich Supercomputing Centre

Damian Alvarez

Abstract


JUWELS is a multi-petaflop modular supercomputer operated by Juelich Supercomputing Centre at Forschungszentrum Juelich as a European and national supercomputing resource for the Gauss Centre for Supercomputing. In addition, JUWELS serves the Earth system modeling community and the AI community within the Helmholtz Association as well. JUWELS currently consists of two modules. The first module deployed in 2018 is the so-called Cluster module. The Cluster is a BullSequana X1000 system with Intel Xeon Skylake-SP processors and Mellanox EDR InfiniBand. The second module deployed in 2020 is the so-called Booster module. The Booster is a BullSequana XH2000 system with 2nd generation AMD EPYC processors, NVIDIA Ampere GPUs and NVIDIA/Mellanox HDR Infiniband. This paper describes in detail the architecture of the system from a users perspective, and additionally provides further insights into the administrative infrastructure used to operate the supercomputer.
