Wafer Scale Engine

“So, having solved this, we were left with a machine that was pretty impressive on most of the metrics, being larger, more cores, 10,000 times the memory bandwidth and 33,000 times the fabric bandwidth.”

“By having 400,000 independent cores, it's perfectly fine if we have a few hundred defects on there, and it's only our job to route the information flows around those defects.”

“And when we showed this the world got pretty excited, so there was a large press splash, and in part that's because this had been presumed to be impossible to achieve.”

“We would have 40,000 amps, and that would actually melt the part if we chose to do it that way, so we had to bring some of the geometric thinking beyond how we think geometry in the models into this three D structure.”
