Abstract
An approach is provided to identifying cache extension sizes that correspond to different partitions that are running on a computer system. The approach extends a first hardware cache associated with a first processing core that is included in the processor's silicon substrate with a first memory allocation from a system memory area, with the system memory area being external to the silicon substrate and the first memory allocation corresponding to one of the plurality of cache extension sizes that corresponds to one of the partitions that is running on the computer system. The approach further extends a second hardware cache associated with a second processing core also included in the processor's silicon substrate with a second memory allocation from the system memory area with the second memory allocation corresponding to another of the cache extension sizes that corresponds to a different partitions that is being executed by the second processing core.
