We address the problem of how to exploit optics for ultrascale High Performance Computing interconnect fabrics. We show that for high port counts these fabrics require multistage topologies regardless of whether electronic or optical switch components are used. Also, per stage electronic buffers remain indispensable for maintaining throughput, lossless-ness(More)
— A crucial part of any high-performance computing system is its interconnection network. In the OSMOSIS project, Corning and IBM are jointly developing a demonstrator interconnect based on optical cell switching with electronic control. Starting from the core set of requirements, we present the system design rationale and show how it impacts the practical(More)
