2015 IEEE 23rd Annual Symposium on High-Performance Interconnects, 2015•ieeexplore.ieee.orgBXI, Bull eXascale Interconnect, is the new interconnection network developed by Atos for
High Performance Computing. In this paper, we first present an overview of the BXI network.
The BXI network is designed and optimized for HPC workloads at very large scale. It is
based on the Portals 4 protocol and permits a complete offload of communication primitives
in hardware, thus enabling independent progress of computation and communication. We
then describe the two BXI ASIC components, the network interface and the BXI switch, and …

The BXI network is designed and optimized for HPC workloads at very large scale. It is based on the Portals 4 protocol and permits a complete offload of communication primitives in hardware, thus enabling independent progress of computation and communication. We then describe the two BXI ASIC components, the network interface and the BXI switch, and the BXI software environment. We finally explain how the Bull exascale platform integrates BXI to build a large scale parallel system and we give some performance estimations.
