The work on the HPCW benchmark will start later. It will build on work in the EU funded project ESCAPE-2, which will develop a representative High Performance Climate and Weather (HPCW) benchmark that isolates key elements in the workflow of weather and climate prediction systems to improve performance and to allow a detailed performance comparison for different hardware. Once ESCAPE-2 ends, ESiWACE2 will take over to extend the HPCW suite to represent a wider range of community models, tests the performance of HPCW benchmarks on different computing systems, including the pre-exascale EuroHPC systems of the EU. The decision which components will be picked and supported will be based on a peer-reviewed process.
