Optical data movement: how nanophotonics is poised to revolutionize interconnection networks in future systems

Wednesday April 13, 2016 at 3:00 pm, Amphi Jade

Performance scalability of next generation computing systems is becoming increasingly constrained by limitations in memory access, power dissipation and chip packaging. The processor-memory communication bottleneck, a major challenge in current multicore processors due to limited pin-out and power budget, becomes a detrimental scaling barrier to data-intensive computing. These challenges have emerged as some of the key hardware barriers to realizing the required memory bandwidths and system wide data movement. Recent manufacturing advances in nanoscale silicon photonic interconnect and switching technologies are providing the infrastructure for developing energy-efficient high-bandwidth optical interconnection networks. Importantly, the insertion of photonics into next-generation computing systems is not a one-to-one replacement. This talk examines the design and potential impact of photonic-enabled architectures for creating new classes of future extreme scale computing.

Keren Bergman is the Charles Batchelor Professor and Chair of Electrical Engineering at Columbia University where she also directs the Lightwave Research Laboratory. She leads multiple research programs on optical interconnection networks for advanced computing systems, data centers, high-performance embedded computing, and chip multiprocessor nanophotonic networks-on-chip. Dr. Bergman holds a Ph.D. from M.I.T. and is a Fellow of the IEEE and of the OSA.
