The Design and Implementation of Reverse Page Table in Page Migration System
Hua Dai · 2004
Page migration is an important policy to exploit memory optimization in CC-NUMA systems,and it is a way to dynamically exploit data locality. The realization of page migration policy involves translation from physical addresses to virtual addresses in virtual memory area,it needs travel through all the process address space with traditional approaches, which is inefficient and costly. Aiming at this problem, an efficient technology to realize translation from physical addresses to virtual addresses-reverse page table is introduced in this paper. Emphasis is put on the design,realization and maintenance for reverse page table
