CPU调度(CPU Scheduling)和上下文切换(Context Switching)是操作系统管理CPU资源、优化程序执行效率的两个基本机制。这些机制确保了多任务环境下,各个进程和线程能公平、高效地共享CPU资源。 2.4.1 CPU调度 CPU调度是指操作系统决定哪个进程或线程应该获得CPU控制权、以及它们获得控制权的顺序的过程。调度算法的目标是优化...
Write a C Program that implements the Round Robin Scheduling algorithm and determines the average waiting time and turnaround time. What is Round Robin Scheduling in C? Round Robin Schedulingis a CPU scheduling algorithm in which each process is executed for a fixed time slot. Since the resource...

进程调度策略(Process Scheduling) 进程调度策略概述 进程调度策略是操作系统用来决定哪个进程在哪个时间运行的算法。在Linux系统中,有多种进程调度策略可供选择,如先来先服务(FCFS)、最短作业优先(SJF)、轮转法等。 进程调度算法 系统中常用的进程调度算法是完全公平调度(CFS)。CFS通过动态调整进程的时间片大小,实现了...
