Abstract: The climate model ICON is the central research tool at the Max Planck Institute for Meteorology (MPI-M). The ICON team presented the first-ever global simulation of the full Earth system at 1.25 km grid spacing, achieving the highest time compression with an unseen number of degrees of freedom. To achieve this landmark simulation, they harnessed the full power of the GH200 Superchip on Alps and JUPITER, and used NVIDIA Grace CPUs and Hopper GPUs to carefully balance Earth’s components in a heterogeneous setup, utilizing optimizing acceleration techniques available in ICON’s codebase.
