This is a different approach in need of CPU scheduling. According to this algorithm when the CPU is free, the process will be assigned which will have the smallest next CPU burst. SJF is optimal which means it will provide the average waiting time for a given set of processes. Let us co...
Non-preemptive Scheduling Algorithms 非抢占式 谁先来,执行谁,执行完了再执行下一个进程。 Shortest-Job-First (SJF) 优先执行cpu执行时间最少的进程。 当一个进程结束,看当前准备队列里,哪个进程执行时间最少,执行那个。执行完毕整个进程再执行下一个。

I am working on CPU Scheduling and I have to calculate the CPU efficiency for each algorithm i.e. First Come Fist Serve, Shortest Job First, Priority and Round Robin. How can I do this?Follow • 2 Add comment 1 Expert Answer Best Newest Oldest Rodney B. answered • 12/...
In this tutorial, we will learn how to predict of CPU burst time for a process in SJF scheduling by static method?ByMonika JhaLast updated : May 08, 2023 InSJF Scheduling, CPU is assigned to the process having the smallest burst time but it can not be imp...
