In this paper we propose and evaluate the Adaptive++ technique, a novel runtime-only data prefetching strategy for software-based distributed shared-memory systems (software DSMs). Adaptive++ improves the performance of regular parallel applications running on software DSMs by using the past

cluster of eight Pentium II PCs connected by a 100Mbps switched Ethernet. Our experiences imply that with the advances of software DSMs and network technologies, the time for pushing the software DSM into the parallel processing mainstream has come and efforts should be made by software DSM researchers

. In this paper we claim that these MSAs are suboptimal for pagebased software distributed shared-memory systems (software DSMs), as they do not consider the specific characteristics of these systems. We support our claim by studying the communication behavior of several applications running on top

Home-based software DSMs provide a simple, effective, and scalable way to build software DSMs. However, the performance of home-based software DSMs is sensitive to the distribution of home pages. This paper introduces our work on migrating home pages adaptively according to the application sharing

In this paper we propose the use of a PCI-based programmable protocol controller for hiding communication and coherence overheads in software DSMs. Our protocol controller provides three different types of overhead tolerance: a) moving basic communication and coherence tasks away from computation

for eliminating synchronization overhead in software DSMs, developing new algorithms to handle situations found in practice. We evaluate the contributions of synchronization elimination algorithms based on 1) dependence analysis, 2) communication analysis, 3) exploiting coherence protocols in software DSMs, and 4

Among the tradeoffs between home-based and homeless software DSMs, a frequently mentioned disadvantage of the home-based software DSM is that it fetches the whole page on a page fault while the homeless protocol fetches diffs only. This paper proposes the write vector technique to reduce message

patterns of different applications, these measures can reduce system overhead of JIAJIA effectively. 1 Introduction Software DSMs suffer from the high communication and coherence-induced overheads that limit performance. The communication cost of software DSMs is evidently high, large granularity

We evaluate the contributions of synchronization elimination algorithms based on 1) dependence analysis, 2) communication analysis, 3) exploiting coherence protocols in software DSMs, and 4

Write detection is essential in multiple-writer protocols to identify writes to shared pages so that these writes can be correctly propagated. Software DSMs that implement multiple-writer protocol normally employ the virtual memory page fault to detect writes to shared pages. It write
