Abstract: This paper presents a design of software distributed shared memory. Inspired by the snooping-based cache coherence, it adopts a new kind of memory coherence protocol which is quite different from the previous ones. The protocol aims to improve the performance of the distributed shared memory by reducing the messages needed in the critical path of execution. This paper further gives the practical implementation and optimization. The preliminary evaluation implies a 45% rise at most in performance.

Key words: distributed shared memory, memory coherence, distributed system
