New Exascale Interconnect Based on Sandia Technology

 French Supercomputer vendor Atos, formerly Bull, recently announced plans to develop a new interconnect for exascale computing systems based on Sandia’s Portals 4 network programming interface. A keynote talk at the recent IEEE Symposium on High-Performance Interconnects entitled “The BXI Interconnect Architecture” detailed the design of the network interface and switch hardware that comprise the interconnect. The network interface is designed specifically to implement the semantics of the Portals 4 interface, including completely offloading several features, such as MPI tag matching.

The abstract and slides from the keynote talk are available at the following site:
