      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.},
