The CExA project (Computing at Exascale with Accelerators at CEA) was launched back in september 2023 in order to help the transition of CEA's HPC codes to GPU in preparation of the arrival of EuroHPC's first exascale systems in Europe and, in particular, the Alice Recoque system which will be hosted at CEA. The goals were to provide 1. a sustainable programming model 2. support for select CEA application demonstrators 3. dissemination of information through trainings and meetings. The programming model chose by the CExA project is Kokkos, a C++ performance portability library developed by US National Laboratories during the Exascale Computing Project, which offers the ability to run on CPU and GPU with a single source code. As the end of the project approaches, CEA has confirmed itself as one of the three main organizations involved in the development of Kokkos, alongside Sandia National Laboratories and Oak Ridge National Laboratory. This collaboration with US National Laboratories allowed the CExA project to help strengthen the presence of CEA in the HPC ecosystem as a whole, in particular through its participation as a general member of the High Performance Software Foundation (HPSF). This poster presents some of the CExA project's contributions to Kokkos and its ecosystem.
