Deadblock Aware Adaptive Eviction Policy for Shared Last-Level Cache

The shared Last-Level Cache (LLC) plays a major role in improving the performance of multicore processor. Multiple applications running concurrently interfere with each other, which results in significant performance degradation for Cache-friendly applications. Prior work mainly reduces interference by cache partitioning. This paper proposes a novel cache replacement Deadblock Aware Adaptive Eviction Policy (DAAEP) that allocates LLC space reasonably according to the different types of applications. Evaluation on SPEC2006 shows that DAAEP provides a weighted speedup of 7.5% over SRRIP and 0.9% over DAAIP on a 2-core system.
