Abstract
An apparatus of an aspect includes a plurality of cores. The plurality of cores are logically grouped into a plurality of clusters. A cluster sharing map-based coherence directory is coupled with the plurality of cores and is to track sharing of data among the plurality of cores. The cluster sharing map-based coherence directory includes a tag array to store corresponding pairs of addresses and cluster identifiers. Each of the addresses is to identify data. Each of the cluster identifiers is to identify one of the clusters. The cluster sharing map-based coherence directory also includes a cluster sharing map array to store cluster sharing maps. Each of the cluster sharing maps corresponds to one of the pairs of addresses and cluster identifiers. Each of the cluster sharing maps is to indicate intra-cluster sharing of data identified by the corresponding address within a cluster identified by the corresponding cluster identifier.
