| 摘 要： | Cache的缺失严重影响着计算机系统的运行效率.现代构件化软件架构中模块化程度越来越高,操作系统中传统的调度策略忽视任务的模块特性,若模块具有特定的代码/数据访问集合,模块间不合理的任务调度会导致严重的Cache缺失.本文提出了一种基于模块的调度策略MBS,可以尽量连续调度同一模块中的任务,尤其适应于构件化的服务系统.分析与实验结果表明,MBS可以有效减少此类系统的Cache缺失,明显提高系统性能.

| Abstract: | Cache miss affects efficiency of computer system seriously.Modulization is very high in modern component based software architecture.The traditional scheduling policy in operation system neglects the modularity of tasks.It leads severe cache miss because of unreasonable task scheduling among modules if each module has a specific code or data set.This paper presents a module based scheduling policy-MBS.The policy tries its best to continuously schedule tasks which run in a same module.It is especially suitab... |
