An Intra-Tile Cache Set Balancing Scheme

This poster describes an intra-tile cache set balancing strategy that exploits the demand imbalance across sets within the same L2 cache bank. This strategy retains some fraction of the working set at underutilized sets so as to satisfy far-flung reuses. It adapts to phase changes in programs and promotes a very flexible sharing among cache sets referred to as many-from-many sharing. Simulation results using a full system simulator demonstrate the effectiveness of the proposed scheme and show that it compares favorably with related cache designs on a 16-way tiled CMP platform.
