Software-transparent hardware predictor for core-to-core data transfer optimization

Abstract

Apparatus, method, and system for implementing a software-transparent hardware predictor for core-to-core data communication optimization are described herein. An embodiment of the apparatus includes a plurality of hardware processor cores each including a private cache; a shared cache that is communicatively coupled to and shared by the plurality of hardware processor cores; and a predictor circuit. The predictor circuit is to track activities relating to a plurality of monitored cache lines in the private cache of a producer hardware processor core (producer core) and to enable a cache line push operation upon determining a target hardware processor core (target core) based on the tracked activities. An execution of the cache line push operation is to cause a plurality of unmonitored cache lines in the private cache of the producer core to be moved to the private cache of the target core.
