The French Alternative Energies and Atomic Energy Commission (CEA) is a large French Research and Technological Organisation (RTO). CEA is a key player in research, development and innovation in four main areas: low carbon energies (nuclear and renewable energies), technological research for industry, fundamental research in the physical sciences and life sciences, defence and security. CEA owns and operates two world-class supercomputing facilities (TERA and TGCC), and deploys related HPC services, for the benefit of national and European research, industry (CCRT) and defence. TGCC hosts and operated the PRACE French Tier-0 system JOLIOT-CURIE funded and made available by GENCI. As part of TGCC, CCRT is a dedicated infrastructure for industrial uses of HPC and related partnerships. CEA is active also in HPC R&D&I all along the value chain (micro-nano-electronics components, system architecture and related co-design, system integration, HPC facilities and infrastructures design and optimisation, energy efficiency, HPC software stacks and middleware, solvers and applications in numerical simulation, big data and AI). CEA is a founding member of ETP4HPC Association for European HPC Technologies, and a member of its Steering Board (ETP4HPC is a private member of EuroHPC JU and contributes to its Research and Innovation Advisory Group) (www-hpc.cea.fr). DSSI (CEA/DIF Information and Simulation Sciences Department) encompasses CEA HPC dedicated division, located in Paris Region. DSSI operates the TERA and TGCC facilities and leads R&D in HPC hardware and software technologies - incl. system architectures, software stacks, middleware, but also HPC tools and applications. DRT is CEA Technological Research Directorate, focusing in particular on information technology and biotechnology for health, and deeply involved in transferring scientific knowledge and innovation to industry and support industry digitalisation at large.


DEEP-SEA

CEA will contribute to:

  • Work package “Co-design applications”, by providing the PATMOS application as a use case.
  • Work package “Measuring, Modelling, Mapping and Monitoring”, by working on application modelling and application to architecture mapping.
  • Work package “Software Architecture and System Software”, by updating its NUMA-aware allocator to support heterogeneous memory systems and support gateways for network communications.
  • Work package “Node-level programming”, by providing a high-level programming model and improving the code generation to maintain performances across different types of architectures.
  • Work package “System-level programming”, by improving its MPI implementation to provide efficient collective algorithms for MSA, and leading the task “Interfaces to support modular/heterogeneous systems”.
