By run-time characteristic analysis of parallel workloads, we found that a majority of shared data accesses of parallel workload has temporal locality. Based on this characteristic, we present a sharing relation cache (SRC for short) based CMP architecture, saving recently used sharing relations to provide destination set information for following cache-to-cache miss requests. Token-SRC protocol integrates SRC into token protocol,reducing network traffic of token protocol.Simulations using SPLASH-2 benchmarks show that, a 16-core CMP system with token-SRC achieved average 15% network traffic reduction of that with token protocol.
