Abstract: A technique includes, in response to a cache miss occurring with a given processing node of a plurality of processing nodes, using a directory-based coherence system for the plurality of processing nodes to regulate snooping of an address that is associated with the cache miss. Using the directory-based coherence system to regulate whether the address is included in a snooping domain is based at least in part on a number of cache misses associated with the address.
