Claim 8:
9. A computer-implemented method of up-eviction in a cache hierarchy, the method comprising:
storing cache lines evicted from a first processor group into a first cache;
down-evicting cache lines from the first cache into a second cache below the first cache in the cache hierarchy;
storing cache lines evicted from a second processor group into the second cache;
up-evicting a first cache line from the second cache to the first cache in response to an eviction of a second cache line from the second processor group to the second cache, wherein the second cache line is evicted from the second processor group into the second cache;
receiving a request for the first cache line from the second processor group; and
providing the up-evicted first cache line from the first cache to the second processor group in response to the request for the first cache line from the second processor group.
