Application-Controlled Coherence Protocols for Scope Consistent Software DSMs

摘要: To use the shared memory programming paradigm in distributed architectures where there is no physically memory, an abstraction must be created. This known as Distributed Shared Memory (DSM). reduce communication costs, DSM systems usually replicate data. approach generates a coherence problem, which generally solved by protocol. Unfortunately, it seems that protocol achieves good performance for large set of applications since most appropriate depends on how application accesses For this reason, interesting system to provide multiple protocols. article presents and evaluates low-overhead mechanism allows choose among was incorporated JIAJIA, implements scope consistency with write-invalidate Our results some benchmarks show significant reduction number messages exchanged, leading better results.
