Abstract: A method, system, and computer program product for augmenting cache replacement operations are provided. The method identifies a set of cache lines within a first cache level of a multilevel cache. A first candidate cache line is identified based on a first replacement scheme of the first cache level. A second candidate cache line is identified based on the first replacement scheme of the first cache level. A replacement cache line is selected for replacement in the first cache level. The replacement cache line is selected from the first candidate cache line and the second candidate cache line and based on the first replacement scheme of the first cache level and a second replacement scheme of a second cache level. The method removes the replacement cache line from the first cache level.
