Performance improvement techniques for software distributed shared memory

This paper presents our novel lazy home-based protocol briefly and two implementation techniques. These techniques are developed by exploiting a relaxed memory consistency model such as scope consistency. First, we present a novel diff integration technique which can solve most diff accumulation problems that are prevalent in migratory DSM applications. Second, we propose a dynamic home migration protocol that solves the static home assignment problem in the original home-based protocol. To evaluate our protocol and techniques, we have done performance tests using well known DSM benchmark applications. The performance results proved our diff integration and dynamic home allocation solve the diff accumulation and wrong static home assignment problems respectively.
