Bull eXascale Interconnect (BXI)

Exascale entails an explosion of performance, of the number of nodes/cores, of data volume and data movement. At such a scale, optimizing the interconnect network that is the backbone of the system becomes a major contributor to global performance. This is why we developped our own new-generation interconnect: the Bull eXascale Interconnect or BXI introduces a paradigm shift in terms of performance, scalability, efficiency, reliability and quality of service for extreme workloads.
