We propose an adaptive cache coherence-replacement scheme for distributed systems that is based on several criteria about the system and applications, with the objective of optimizing the distributed cache system performance. We examine different distributed platforms (shared memory systems, distributed memory systems, and web proxy cache systems) and the potential of incorporating coherency-replacement issues in the cache memory management system. Our coherence-replacement scheme assigns a replacement priority value to each cache block according to a set of criteria to decide which block to remove. The goal is to provide an effective utilization of the distributed cache memory and a good application performance.
