Abstract
A computer-implemented method includes receiving a request to access a cache entry in a shared cache. The request references a synonym for the cache entry. A cache directory of the shared cache includes, for each cache entry of the shared cache, a first-ranked synonym slot for storing a most recently used synonym for the cache entry and a second-ranked synonym slot for storing a second most recently used synonym for the cache entry. The method includes, based on receiving the request, writing contents of the first-ranked synonym slot for the cache entry to the second-ranked synonym slot for the cache entry, and writing the synonym referenced in the request to the first-ranked synonym slot for the cache entry.
