BALTIMORE, Oct. 16, 2023 – The 2023 John von Neumann Theory Prize, awarded by INFORMS, is bestowed to Christos H. Papadimitriou and Mihalis Yannakakis for their significant contributions to the field of operations research and analytics. The combined work of Papadimitriou and Yannakakis, both from Columbia University, has focused on computational complexity theory and providing an […]
@HPCpodcast: Silicon Photonics – Columbia Prof. Keren Bergman on the Why, How and When of a Technology that Could Transform HPC
April 10, 2023 by
Silicon photonics has the potential to transform HPC: it’s a dual-threat interconnect technology that could – if and when it is wrestled into commercial, cost-effective form – move data within chips and systems much faster than conventional, copper-based interconnects while also delivering far greater energy efficiency. Venture-backed start-ups and established tech companies….
Altair Invests $10M in Columbia Univ. Photonics Startup

TROY, Mich., December 20, 2022 – Altair (Nasdaq: ALTR) has invested $10 million in Xscape Photonics, a start-up that developed patented technology for photonic chips for ultrahigh-bandwidth connections inside data centers and high-performance computing (HPC) systems (see related story). In its announcement, Altair said, “Until now, computing leveraged a traditional electronic approach to moving vast […]
Dr Keren Bergman previews ISC Keynote on Optical Computing for HPC
June 24, 2018 by
In this special guest feature from Scientific Computing World, Dr Keren Bergman, Professor of Electrical Engineering at the School of Engineering and Applied Science, Columbia University discusses her keynote on the development of silicon photonics for HPC ahead of her Tuesday keynote presentation at ISC 2018. “So today we are able to make all the components of photonic links and this includes 50 GHz data modulators, 50 GHz receivers, nanosecond scale switches all kinds of structures and we can do wave division multiplexing into these interconnect structures. The capabilities are just enormous.”
