Abstract
A system, method, and program product are provided that identifies a cache set using Segment LookAside Buffer attributes. When an effective address is requested, an attempt is made to load the received effective address from an L2 cache. When this attempt results in a cache miss, the system identifies a segment within the Segment LookAside Buffer that includes the effective address. A class identifier is retrieved from the identified segment within the Segment LookAside Buffer. This class identifier identifies a cache set selected from the cache for replacement. Data is then reloaded into the cache set of the cache by using the retrieved class identifier that corresponds to the effective address.
