Pittsburgh Supercomputing Center
One of the highlights of Hot Chips 2019 was the presentation of the Cerebras Wafer Scale Engine - an AI processor chip that was as big as a wafer, containing 1.2 trillion transistors and set at over 46225 square millimetres of silicon. This was enabled through breakthrough techniques in cross-reticle patterning, but with the level of redundancy built into the design, ensured a yield of 100%, every time. The first WSE system, the CS-1, was put out on display at Supercomputing 2019, where we got a chance to bite into the design with Andrew Feldman, the founder and CEO of Cerebras. Unfortunately I never got around to writing up my discussions with Andrew, however what we did learn at the time is that the CS1...
