Abstract

Directory coherence protocols, available in any NUMA system suffer from performance degradation when dealing with 3-hop fetches. This is especially a problem in commercial workloads (due to the sharing patterns). Today several algorithms exist to monitor and predict the 3-hop fetches to accelerate performance. Presented here is a method that takes this performance acceleration a step forward.
