Abstract:
A processor of an aspect includes a plurality of logical processors each having one or more corresponding lower level caches. A shared higher level cache is shared by the plurality of logical processors. The shared higher level cache includes a distributed cache slice for each of the logical processors. The processor includes logic to direct an access that misses in one or more lower level caches of a corresponding logical processor to a subset of the distributed cache slices in a virtual cluster that corresponds to the logical processor. Other processors, methods, and systems are also disclosed.
