Abstract: In this talk we review the architecture of large scale high-performance computing interconnects and analyze where optical technologies can play a major role in the future. Today, optical cables are largely used in supercomputers and datacenters, principally for meter-scale communications. Through improved integration of optical transceivers, photonic transmission will also be progressively leveraged for shorter distances in the next years. The figures of merit of future on-chip optical transceivers, deeply integrated within the compute nodes and servers, will be presented. We also review the prospects of optical switching. Switching using photonic devices is undoubtedly subject to very distinct rules and constraints when compared to its electrical counterpart, and its insertion in very large scale architectures must be carefully engineered to be advantageous. The Flexfly architecture, in which low-radix optical switches are integrated in a dragonfly topology, is presented as an example
Bio: Sébastien Rumley received the M.S. and Ph.D. degrees (in communication system) from EPFL, Switzerland, in 2005 and 2011. Since 2012 he has been with the Lightwave Research Laboratory, Columbia University, New York, as Research Scientist since 2014. His research focuses on multilayer, cross-scale modeling and optimization of large scale interconnection networks. This includes analysis of nanophotonic devices and the integration thereof in next generation computing systems, network topology design and dimensioning, characterization of data-movement requirements and end-to-end evaluation of interconnect power consumption.
