SE: How do you define a compute cluster, and what does a chip architect need to know? Emmer: From a chip architect’s point of view, a compute cluster is not just a collection of servers. Maybe there are big companies with that much inference demand, but training typically requires large clusters to be available and pipelined. SE: Compute clusters are common in AI laboratories, life sciences, high-frequency trading, and other specialized applications. It is something that we are doing in the U.S., and we have several of these exascale compute clusters already operational.
