摘要: A system and method for a multilevel region coherence protocol use in Region Coherence Arrays (RCAs) deployed clustered shared-memory multiprocessor systems which optimize cache-to-cache transfers (interventions) by using hint bits each RCA to allow memory requests lines of the be optimally sent only determined portion without broadcasting all processors system. sufficient number are used uniquely identify level system's interconnect hierarchy predict likely includes processor that has cached copies data from region.
