ABSTRACT:
Methods and systems for shared cache eviction in a multi-core processing environment having a cache shared by a plurality of processor cores are provided. Embodiments include receiving from a processor core a request to load a cache line in the shared cache; determining whether the shared cache is full; determining whether a cache line is stored in the shared cache that has been accessed by fewer than all the processor cores sharing the cache if the shared cache is full; and evicting a cache line that has been accessed by fewer than all the processor cores sharing the cache if a cache line is stored in the shared cache that has been accessed by fewer than all the processor cores sharing the cache.
