在多道程序和多任务系统中，系统内同时处于就绪状态的进程可能有若干个。也就是说能运行的进程数大于处理机个数。为了使系统中的进程能有条不紊地工作，必须选用某种调度策略，选择一进程占用处理机。要求学生设计一个模拟处理机调度算法，以巩固和加深处理机调度的概念-In multi-channel process and multi-tasking system, the system is in a state of readiness at the same time the process may have several. This means that the process will be able to run more than the number of processors. In order to make the process of the system can work in an orderly manner, we must choose some kind of scheduling strategy, the process to select a processor occupancy. Requires students to design an analog processor scheduling algorithm, so as to consolidate and deepen the concept of processor scheduling
