摘要

Memory interference is a critical impediment to system performance in CMP systems. To address this problem, we first propose a Dynamically Proportional Bandwidth Throttling policy (DPBT), which dynamically throttles back memory-intensive applications based on their memory access behavior. DPBT achieves a more balance memory bandwidth partitioning. Moreover, we improve the previous memory channel partitioning scheme by integrating it with a bank partitioning. We further integrate DPBT with the improved memory channel partitioning scheme and a memory scheduling policy to leverage the architecture advantages, and present a Stage Memory Resource Management Method (SRM). Experimental results show that DPBT improves system throughput/fairness by 13.5%/31.1%. SRM provides 27.1% better system throughput and 34.8% better system fairness.
