DESCRIPTION:Abstract: High-performance systems are increasingly bottlenecke
 d by the energy and communications costs of interconnecting numerous compu
 te and memory resources. Current systems face a gap of nearly two orders o
 f magnitude between on-chip\, intra-socket\, communication capacities\, an
 d the capacities of links transporting data over longer distances. The per
  bit energy cost of data movement dominates that of data processing\, as d
 oes density\, throughput\, and latency. Integrated silicon photonics offer
  the opportunity of optical connectivity that delivers high off-chip commu
 nication bandwidth densities with low power consumption. To realize these 
 benefits the co-integration of photonics with the compute and memory is cr
 itical. This talk will cover approaches for leveraging photonic IO that ca
 n scale to realize Petabit/s chip escape bandwidths with sub-picojoule/bit
  energy consumption\, as well as new architectural approaches that enable 
 flexible connectivity tailored to accelerate distributed AI/ML application
 s.\n\nBio: Keren Bergman is the Charles Batchelor Professor of Electrical 
 Engineering at Columbia University where she also serves as the Faculty Di
 rector of the Columbia Nano Initiative. Bergman received the B.S. from Buc
 knell University in 1988\, and the M.S. in 1991 and Ph.D. in 1994 from M.I
 .T. all in Electrical Engineering. At Columbia\, Bergman leads the Lightwa
 ve Research Laboratory encompassing multiple cross-disciplinary programs a
 t the intersection of computing and photonics. Since 2023 Bergman is the D
 irector of the Center for Ubiquitous Connectivity (CUbiC)\, a 5-year multi
 -university center funded by DARPA and the Semiconductor Research Corporat
 ion (SRC) under the Joint University Microelectronics Program 2.0 (JUMP 2.
 0). Bergman serves on the Leadership Council of the American Institute of 
 Manufacturing (AIM) Photonics leading projects that support the institute
 ’s silicon photonics manufacturing capabilities and Datacom applications
 . She is the recipient of the IEEE Photonics Engineering Award and is a Fe
 llow of Optica and IEEE.\n\nPlease note the Zoom link at the bottom of thi
