A system and method for supporting targeted stores in a shared-memory multiprocessor. A targeted store enables a first processor to push a cache line to be stored in a cache memory of a second processor. This eliminates the need for multiple cache-coherence operations to transfer the cache line from the first processor to the second processor. More specifically, the disclosed embodiments provide a system that notifies a waiting thread when a targeted store is directed to monitored memory locations. During operation, the system receives a targeted store which is directed to a specific cache in a shared-memory multiprocessor system. In response, the system examines a destination address for the targeted store to determine whether the targeted store is directed to a monitored memory location which is being monitored for a thread associated with the specific cache. If so, the system informs the thread about the targeted store.
