ESiWACE2

Excellence in Simulation of Weather and Climate in Europe, Phase 2

ESiWACE2 will leverage the potential of the envisaged EuroHPC pre-exascale systems to push European climate and weather codes to world-leading spatial resolution for production-ready simulations, including the associated data management and data analytics workflows. For this goal, the portfolio of climate models supported by the project has been extended with respect to the prototype-like demonstrators of ESiWACE1. Besides, while the central focus of ESiWACE2 lies on achieving scientific performance goals with HPC systems that will become available within the next four years, research and development to prepare the community for the systems of the exascale era constitutes another project goal. 

These developments will be complemented by the establishment of new technologies such as domain-specific languages and tools to minimise data output for ensemble runs. Co-design between model developers, HPC manufacturers and HPC centres is to be fostered, in particular through the design and employment of High-Performance Climate and Weather benchmarks, with the first version of these benchmarks feeding into ESiWACE2 through the FET-HPC research project ESCAPE-2. Additionally, training and dedicated services will be set up to enable the wider community to efficiently use upcoming pre-exascale and exascale supercomputers.
