Abstract : |
This paper presents a new cache consistency scheme for hierarchically-structured sharedmemory multiprocessors. The scheme is simple, fast and efficient, and it does not require a large amount of state information to be maintained. The scheme exploits the broadcast capability of these systems, but limits the extent of the broadcasts by means of a novel filtering mechanism. As a specific example, it is shown how the proposed cache consistency scheme can be implemented on the Hector multiprocessor architecture. Using trace-driven simulations, it is demonstrated that the scheme is scalable and performs well for common applications., |
