Join us as we welcome Professor Puneet Gupta from the University of California, Los Angeles as he presents "Scale-Out Computing Systems: Waferscale and Photonic Examples."
Abstract: Increasing demand for compute from machine learning workloads while slowing down conventional technology scaling has made the search for alternative scaling paradigms imperative.
In this talk, Gupta will discuss two such alternatives: chiplet-based waferscale computing and leveraging photonics for compute. First, he motivates benefits of waferscale computing using a GPU example, then describes efforts to design a 2048-chiplet waferscale system. Next, he looks further into the future and describes benefits and pitfalls for photonic computing with the example of the PhotoFourier architecture and ongoing effort to prototype it.
PUNEET GUPTA received a bachelor’s degree in electrical engineering from the Indian Institute of Technology Delhi in 2000, and a doctoral degree from the University of California, San Diego in 2007. He is a faculty member of the electrical and computer engineering department at the University of California, Los Angeles. He co-founded Blaze DFM Inc. in 2004 and served as its product architect until 2007. He has authored more than 200 papers, holds 18 U.S. patents, authored a book and two book chapters in the areas of design-technology co-optimization as well as variability/reliability aware architectures. Gupta is an IEEE Fellow and received an NSF CAREER Award, the ACM/SIGDA Outstanding New Faculty Award, SRC Inventor Recognition Award, and the IBM Faculty Award. He has led the multi-university IMPACT+ Center which focused on future semiconductor technologies. He leads the system benchmarking theme within the SRC CHIMES JUMP 2.0 center.
