摘要
页迁移是分布共享存储系统中动态开发数据局部性的一种优化策略,但体系结构相关性及时空开销限制了它在实际系统中的应用。本文立足于CC-NUMA系统和具有单地址空间映象的cluster系统,提出了一种通用的、无需特殊硬件支持的、基于瞬时访问信息的动态页迁移机制,并给出了基于Linux操作系统内核的实现方案。
Page migration is an optimization policy to exploit data locality in distributed shared-memory systems but hindered by its temporal and spatial cost and its architectural dependence. In this paper, we propose a common instantaneous information-based page migration mechanism on the standpoint of CC-NUMA and cluster systems with single system image support. Finally we bring along the implementation scheme of our policy based on the Linux kernel.
