The RED-SEA project prepares a new-generation European Network Interconnect, capable of powering the EU Exascale systems to come, leveraging efficient European interconnect technology (BXI) associated with a standard and mature technology (Ethernet), in full coordination with other EU-funded initiatives. RED-SEA brings together the top European academic centres and the key European industrial forces in the domain of interconnect networks, with a consortium gathering 12 partners from 6 countries.

RED-SEA will build upon the European interconnect BXI (BullSequana eXascale Interconnect), together with standard and mature technology (Ethernet) and previous EU-funded initiatives to provide a competitive and efficient network solution for the exascale era and beyond. This involves developing the key IPs and the software environment that will deliver:

• scalability, while maintaining an acceptable total cost ofownership and power efficiency;
• virtualization and security, to allow various applications to efficiently and safely share an HPC system;
• Quality-of-service and congestion management to make it possible to share the platform among users and applications with different demands;
• reliability at scale, because fault tolerance is a key concern in a system with a very large number of components;
• support of high-bandwidth low-latency HPC Ethernet, as HPC systems increasingly need to interact
• securely with the outside world, including public clouds, edge servers or third party HPC systems;
• support of heterogeneous programming model and runtimes to facilitate the convergence of HPC and HPDA;
• support for low-power processors and accelerators.
