Abstract
Methods and apparatuses to control cache line coherence are described. A hardware processor may include a first processor core with a cache to store a cache line, a second set of processor cores that each include a cache to store a copy of the cache line, and cache coherence logic to aggregate in a tag directory an acknowledgment message from each of the second set of processor cores in response to a request from the first processor core to modify the copy of the cache line in each of the second set of processor cores and send a consolidated acknowledgment message to the first processor core.
