Adaptive Write Detection in Home-Based Software DSMs

This paper proposes a new write detection scheme in a home-based software DSM called JIAJIA[3]. It automatically recognizes single write to a shared page by its home host and assumes the page will continue to be written by the home host in the future until the page is written by remote hosts. During the period the page is assumed to be singly written by its home host, no write detection of this home page is required and page faults caused by home host write detection can be avoided. Evaluation with some well-known DSM benchmarks reveals that the new write detection can reduce page faults dramatically and improve performance significantly
