Schedulingis important in many different computer environments. One of the most important areas is scheduling which programs will work on the CPU. This task is handled by the Operating System (OS) of the computer and there are many different ways in which we can choose to configure programs. ...
一、技术总结 1.vmstat Linux系统上 vmstat 命令的作用是“Report virtual memory statistics”。 2.scheduling algorithms (1)FCFS(first-come first-serve) (2)SJF(shortest-job-first) 准确的叫法应该是“shortest-next-CPU-burst”。 二、英语总结(生词:4) 1.convoy (1)convoy: con-("together") + via(...
This paper gets into task scheduling in operating systems. Main methods and techniques of scheduling are presented. With a short introduction including long-term, medium-term, short term and dispatcher scheduling, main concepts are described. We will also study the scheduling algorithms (their ...

By the way, the world went through a long period (late 80's, early 90's) in which the most popular operating systems (DOS, Mac) had NO sophisticated CPU scheduling algorithms. They were single threaded and ran one process at a time until the user directs them to run another process....
