Abstract

Examples described herein relate to processor circuitry to issue a cache coherence message to a central processing unit (CPU) cluster by selection of a target cluster and issuance of the request to the target cluster, wherein the target cluster comprises the cluster or the target cluster is directly connected to the cluster. In some examples, the selected target cluster is associated with a minimum number of die boundary traversals. In some examples, the processor circuitry is to read an address range for the cluster to identify the target cluster using a single range check over memory regions including local and remote clusters. In some examples, issuance of the cache coherence message to a cluster is to cause the cache coherence message to traverse one or more die interconnections to reach the target cluster.
