A Hot-Page Aware Hybrid-Copy Migration Method

Hybrid-copy migration is a practical mean in cloud computing for memory intensive workload. But it does not perform perfectly in fetching remote pages. Aiming at solving this problem, we present a hot-page hybrid-copy migration method. We design a hot-page capturer to find out hot-pages, and a hot-page syringe to push hot-pages into transmission queue. We present an evaluation called page fault interval time, to evaluate the performance of hybrid-copy migration. The experimental results show that our method can extend the free part in page fault interval time about 19.79%, reduce the amount of remote page faults about 9.6%, and finally improve the performance of hybrid-copy migration.
