ESiWACE Service 3 will start later. It will build on work in the EU funded project ESCAPE-2. The project ESCAPE-2 will develop a benchmark suite called HPCW 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. ESiWACE2 extends 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.
