时间片轮转调度算法(Round Robin Scheduling)是一种基于时间片的进程调度算法,旨在公平地分配CPU时间给各个就绪进程。 时间片轮转调度算法的工作过程如下: 将所有就绪进程按照到达时间的顺序放入就绪队列。 设定一个固定的时间片大小,通常为几十毫秒。 从就绪队列中选择一个进程,分配给它一个时间片的CPU时间。 若该进...
Convoy Effec:假设有一个CPU密集型(大突发时间)进程,在准备队列中,其他几个进程的突发时间相对爆发时间较少,但有输入/输出(I/O)约束(经常需要I/O操作)。 然后会发生以下情况: I/O绑定的进程首先被分配CPU时间。由于它们的CPU密集度较低。由于它们的CPU密集度较低,很快就会被执行,然后转到I/O队列。 现在,CPU...

遵循非抢占式调度原则的作业或进程调度方法被称为最短作业优先调度。在这种情况下,调度程序从等待列表中选择完成时间最短的作业或进程,并将CPU分配给它。因为SJF比FIFO更优化,可以减少平均等待时间,从而提高吞吐量,所以它优于FIFO。 抢占式和非抢占式SJF算法都是可行的。最短剩余时间优先调度是抢占式调度的另一个名...
