ABSTRACT

This paper proposes a new directory-based cache coherence scheme which significantly reduces coherence traffic by omitting unnecessary write-backs to home nodes for migratory exclusively-modified data. The proposed protocol is well matched to such migratory data which are accessed in turn by processors, since write-backs to home nodes are never used for such migratory sharing. The simulation result shows that our protocol dramatically alleviate the coherence traffic, and the traffic reduction could also lead to shorten network latency and execution time.
