The selected proposals will have to:

  • Develop a roadmap for European scalable inter-node interconnects targeting HPC exascale and post-exascale systems. The roadmap should take into account the EuroHPC supported work in this area such as the components being developed in the EuroHPC RED-SEA project  as well as in the area of processors and accelerators.
  • Develop the inter-node interconnect hardware addressing design, development, testing and tape-out as well as integration in test-beds. The work should foster synergies with the EuroHPC supported work in the area of processors and accelerators.
  • Develop the software, installation, configuration and management tools for the developed interconnect, driven by the needs of relevant HPC workflows and application requirements.
  • Address issues like high bandwidth, low latency, power efficiency, virtualisation, scalability, reliability, security, etc.
