Abstract
As an innovative grid computing technique for sharing the distributed memory resources in a high-speed widearea network, RAM Grid exploits the distributed computing nodes, and provides remote memory for the user nodes which are short of memory. The performance of RAM Grid is constrained with the expensive network communication cost. In order to hide the latency of remote memory access and improve the performance, the authors proposed the push-based prefetching to enable the memory providers to push the potential useful pages to the user nodes. For each provider, it employs sequential pattern mining techniques, which adapts to the characteristics of memory page access sequences, on locating useful memory pages for prefetching. They have verified the effectiveness of the proposed method through trace-driven simulations.
