DiskScheduling Algorithm 磁盘调度在多道程序设计的计算机系统中，各个进程可能会不断提出不同的对磁盘进行读/写操作的请求。由于有时候这些进程的发送 请求的速度比磁盘响应的还要快，因此我们有必要为每个磁盘设备建立一个等待队列，常用的磁盘调度算法有以下四种： 先来先服务算法（FCFS）， 最短寻道时间优先算法（...

We introduce a new deadline driven disk scheduling algorithm designed for multimedia servers. The proposed algorithm supports real time requests with multiple priorities, e.g., those for different object classes in digital library applications. The proposed algorithm enhances utilization of disk bandwidth...

effect (as I said, memory is not a problem at all on my system, but this is a question of fair scheduling of qBittorrent with other processes, and it's legitimate for users to want to give lower priority to qBittorrent I/O when the applciation is just left rtuennign in the back...

这篇文章是参考好几篇博客而整理的关于磁盘I/O调度算法的内容,都比较基础,应该也挺重要。文中涉及到的代码的完整源码都放在了我的Github关于算法部分当中了。 磁盘调度算法 在操作系统中,各个进程可能会不断提出不同的对磁盘进行读/写操作的请求,有时候这些进程的发送请求的速度比磁盘响应的还要快,所以需要为每个磁...
各位同学大家好,在这个小节中我们会学习一个很重要很高频的考点磁盘调度算法,首先我们会介绍一次读磁盘操作或者一次写磁盘操作到底需要多少时间,我们应该怎么计算。它总共分为寻道时间、延迟时间和传输时间这样三个部分 磁盘调度算法的不同会影响寻找时间的长短,所以选择一个合适的磁盘调度算法,对于磁盘...
