选择一个调度算法，实现处理器调度。

二、实习目的

在采用多道程序设计的系统中，往往若干个进程同时处于就绪状态。当就绪进程个数大于处理器数时，就必须依照某种策略来决定那些进程优先占有处理器。本实习模拟在单处理器情况下的处理器调度，加深了解处理器调度的工作。

-choose a scheduling algorithm to achieve processor scheduling. 2, internships aim of the introduction of multi-channel programming systems, a number of process often at the same time readiness. When the number is greater than the process in place when the number of processors, it must, in accordance with a strategy to determine who has priority process processor. This attachment to the single-processor simulation of the processor scheduling, a better understanding of the processor scheduling work.
