More than 11 percent of the GPUs at Meta’s Prometheus supercluster in New Albany, Ohio, are either dead or sitting idle waiting to step in when the next drops out, Zuckercorp revealed this week. The massive pool of redundant GPUs is just one of several measures the hyperscaler has taken to keep its AI training runs on track. Prometheus is among Meta's largest compute deployments to date.
