The European Commission (EC) and the European High Performance Computing Joint Undertaking (EuroHPC JU) are investing in preparing application domains for the upcoming exascale supercomputers presently being developed in Europe. In this context, ten Centres of Excellence (CoEs) have been recently launched to support research and innovation actions that will develop and adapt HPC for the exascale and post-exascale era. Coordinated by the Spanish Barcelona Supercomputing Center-Centro Nacional de Supercomputación (BSC-CNS), the 3rd phase of the Centre of Excellence in Simulation of Weather and Climate in Europe, ESiWACE3, is one of the CoEs funded by the EuroHPC JU and co-funded by the EC. It aims to substantially improve the efficiency and productivity of numerical weather and climate simulation, supporting the entire end-to-end workflow of global Earth System modelling. The purpose of ESiWACE3 is to prepare the European weather and climate community to use future exascale supercomputing systems in a co-design effort involving modelling groups, computer scientists, and the HPC industry. These efforts will contribute to stretching the capability and capacity of existing software and hardware to the limits and, therefore, directly impact both weather and climate modelling and the competitiveness of the European HPC industry. The ambition is to establish ESiWACE3 as a science community platform providing domain-specific services, benchmarks, and tools, envisioning this platform as a primary driver of a continuous innovation and co-design cycle. The close interaction of ESiWACE3 with two well-established European networks—the Research Infrastructure for the European Network for Earth System Modelling (ENES-RI) and the European Centre for Medium-Range Weather Forecasts (ECMWF, partner of the Consortium)—ensures the close embedding of the CoE in the overall strategy of the European weather and climate community. In particular, the work developed within ESiWACE3 will fundamentally contribute to the technical details of developing two Digital Twins of the Earth to monitor and simulate natural and human activity, which will be implemented as part of the EC's Destination Earth initiative. Moreover, two of the pre-exascale systems, LUMI at CSC and the planned MareNostrum5 at BSC are present in the ESiWACE3 Consortium. ESiWACE - Towards exascale weather and climate simulation |
