Might it not be more optimal to attach the individual GPU dielets onto a silicon interposer to avoid the yield issues that are inherent when making a large monolithic chip, and save some of the overheads of dealing with dead dielets? I think I read about some researchers/companies going that route but haven't kept up.
- lsb 6y agoPart of the genius of the Cerebras on-chip routing is that it can route around malfunctioning dielets.
