      abstract     = {The first exascale supercomputer in Europe, JUPITER, is
                      currently being built using the NVIDIA Grace Hopper
                      superchips as main building blocks. JUPITER is designed to
                      provide computing power for both data-driven (AI) workloads
                      and numerics-based simulation workloads. For both workload
                      types, and particularly for PDE-based simulations,
                      high-performance sparse linear algebra operations are
                      crucial. In this paper, we analyze the performance levels
                      that sparse linear algebra operations can achieve on the
                      JUPITER supercomputer and identify algorithmic modifications
                      that can improve performance by acknowledging the Grace
                      Hopper architecture.},
