This paper studies the isolated and combined effects of several latency-tolerance techniques for software-based distributed shared-memory systems (software DSM5). More specifically, we focus on data prefetching, update-based coherence, and single-writer optimizations for page-based software DSM5. Our experimental results with six parallel applications show that, when these techniques are carefully combined, they can provide running time and speedup improvements of up to 54 percent and 110 percent, respectively, on a cluster of eight PCs.
