Abstract
In one embodiment, a processor includes: a plurality of cores each to independently execute instructions; a shared cache memory coupled to the plurality of cores and having a plurality of clusters each associated with one or more of the plurality of cores; a plurality of cache activity monitors each associated with one of the plurality of clusters, where each cache activity monitor is to monitor one or more performance metrics of the corresponding cluster and to output cache metric information; a plurality of thermal sensors each associated with one of the plurality of clusters and to output thermal information; and a logic coupled to the plurality of cores to receive the cache metric information from the plurality of cache activity monitors and the thermal information and to schedule one or more threads to a selected core based at least in part on the cache metric information and the thermal information for the cluster associated with the selected core. Other embodiments are described and claimed.
