Building on the successful BXI (BullSequana eXascale Interconnect) European HPC Interconnect, NET4EXA will continue the development of the next generation of European Interconnects (BXIv3).

The earlier versions BXIv1 and BXIv2 have been deployed in European supercomputers ranking among the TOP15.

The project will showcase a fully functional Pilot at TRL 8, poised for adoption and integration into exascale and post-exascale European supercomputers.

The project will contribute by offering analysis and preliminary design for upcoming interconnect features, thus paving the way for continued progress in the field. NET4EXA will also prepare the subsequent version, BXIv4.
