DESCRIPTION:Dr. Sébastien Rumley\, Columbia University\, New York\nAbstra
 ct: In this talk we review the architecture of large scale high-performanc
 e computing interconnects and analyze where optical technologies can play 
 a major role in the future. Today\, optical cables are largely used in sup
 ercomputers and datacenters\, principally for meter-scale communications. 
 Through improved integration of optical transceivers\, photonic transmissi
 on will also be progressively leveraged for shorter distances in the next 
 years. The figures of merit of future on-chip optical transceivers\, deepl
 y integrated within the compute nodes and servers\, will be presented. We 
 also review the prospects of optical switching. Switching using photonic d
 evices is undoubtedly subject to very distinct rules and constraints when 
 compared to its electrical counterpart\, and its insertion in very large s
 cale architectures must be carefully engineered to be advantageous. The Fl
 exfly architecture\, in which low-radix optical switches are integrated in
  a dragonfly topology\, is presented as an example\n\nBio: Sébastien Ruml
 ey 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 Lightwa
 ve Research Laboratory\, Columbia University\, New York\, as Research Scie
 ntist since 2014. His research focuses on multilayer\, cross-scale modelin
 g and optimization of large scale interconnection networks. This includes 
 analysis of nanophotonic devices and the integration thereof in next gener
 ation computing systems\, network topology design and dimensioning\, chara
 cterization of data-movement requirements and end-to-end evaluation of int
 erconnect power consumption.
