页迁移:一种动态开发数据局部性的方法

Page Migration:A Dynamic Way to Exploit Data Locality

页迁移技术包括页迁移和页复制两个方面， 是一种动态开发数据局部性的方法。由于ＣＣ－ＮＵＭＡ机器对远程访问的延迟是本地访问延迟的３～５倍，数据的局部性对ＣＣ－ＮＵＭＡ机器有较大的影响， 静态开发数据的局部性有其局限性。本文主要针对ＣＣ－ＮＵＭＡ体系结构， 讨论了动态开发数据局部性的方法

Page migration including page migration and page replication is a way to exploit data locality.As the remote access latency is expected to be 3 to 5 times the local access latency for CC NUMA machines,data locality has great influence upon the performance of CC NUMA machines.The static ways to exploit data locality are limited.This paper discusses a dynamic way to exploit data locality and page migration for CC NUMA machines.
