That’s an interesting point. In architecture class (which was basic and abstract so I’m sure Cerebras is doing something much more clever), we learned that defects cluster, but this is a good thing. A bunch of defects clustering on one core takes out the core, a bunch of defects not clustering could take out… a bunch of cores, maybe rendering the whole chip useless.

I wonder why they don’t like clustering. I could imagine in a network of little cores, maybe enough defects clustered on the network could… sort of overwhelm it, maybe?

Also I wonder how much they benefit from being on one giant wafer. It is definitely cool as hell. But could chiplets eat away at their advantage?
