TurboTag: Lookup filtering to reduce coherence directory power


On-chip coherence directories of today's multi-core systems are not energy efficient. Coherence directories dissipate a significant fraction of their power on unnecessary lookups when running commercial server and scientific workloads. These workloads have large working sets that are beyond the reach of on-chip caches of modern processors. Limited to… (More)
