摘要
进程调度是操作系统内核的重要功能。组调度是当前操作系统内核调度算法的发展方向之一,在linux最新内核中,在完全公平调度算法CFS的基础之上,实现了基于分组的进程调度。该文以Kernel2.6.27源代码为参考,从数据结构和程序实现等方面对组调度算法做了分析,并举例说明了组调度应用的方法。
As one of the directions of scheduling algorithm in OS Kernel,Group Scheduler is realized in Linux Kernel.According to the source code of Kernel 2.6.27,an analysis of Group Scheduler from such aspects as data structure and programming is made,and a examples for illustrate the application of group scheduler is given in this paper.
