• High node counts (hundreds of thousands of nodes, millions of cores) require new levels of parallelism and communication
• Heterogeneous computing devices: modern accelerators (such as GPUs) processing data at high rates (tens of TFlop/s) significantly increase data rates
• These results in huge increases of interconnect network traffic

Next generation of Exascale systems will require innovative, highly efficient interconnect networks

• Must support high node counts and massively parallel processing systems
• Providing a set of “smart” features (i.e., efficient network resource management, in-network computing, fabric mgt) allowing applications to scale efficiently at Exascale levels and beyond
• Support power-efficient accelerators and compute units, and wide-spread data-centric and AI-related applications

Goal: covers the variety of solutions (to the above network requirements)

• Improve the current Atos BXI technology (Bullsequana eXascale Interconnect)
• Contribute to the design and specification of the next BXI generation to anticipating future systems requirements
• Enrich the European interconnect technology ecosystem to foster new kinds of networks, system SW and applications
