CCHIME: A Cache Coherent Hybrid Interconnected Memory Extension

This paper presents a hybrid shared memory architecture which combines the scalability of a multistage interconnection network with the contention reduction benefits of coherent caches. We achieve this by replacing the memory modules and final stages of a multistage interconnection network with clusters of coherent caches. The performance of Cache Coherent Hybrid Interconnected Memory Extension (CCHIME) is evaluated by analyzing the results of extensive simulations of the network and coherent cache clusters. These results indicate that the CCHIME architecture can achieve lower memory access latencies and higher throughputs than typical multistage interconnection networks.
