Time-slicing Scheduling(时间片调度) Each process gets a small unit of CPU time (time quantum), usually 10-100 milliseconds. After this time has elapsed, the process is preempted and added to the end of the ready queue.(每个进程得到一个小单位的CPU时间(时间量子),通常为10-100ms。在这个时间...
Waiting time(等待时间):The amount of time a process has been waiting in the ready queue (一个进程在准备队列中等待的时间) Another metric isfairness(公平性): Performance and fairness are often at odds in scheduling.(性能和公平性在调度中往往是不一致的) 0x01 Algorithm1:先进先出 (FIFO) First ...
TheSJF scheduling algorithmis better thanFCFSas the problems like the convoy effect (if a process is very large, the processes which arrive after that process has to wait for a much longer time even if they have a job of only a few time units)does not occur in this type of schedule. ...

In this article, we are going to learn about implementation of shortest job first (SJF) Non-preemptive scheduling algorithm using C++ program. Submitted by Aleesha Ali, on January 26, 2018 Non-preemptive: We cannot remove a process until it completes it execution....
My Dream Team had to work on scheduling, posting different students at different events through out the day. Always have accountability every hour on where these students were, who was on break, who was working where etc. The Dream Team managed all the in’s and outs of this event and ...
=Sum of Turnaround Time of each Process/ Number of Processes= (6 + 19+ 6 + 5) / 4 = 9 msThe waiting time is given by the time that each process waits in the ready queue. For a non-preemptive scheduling algorithm, waiting time of each process can be simply calculated as −...
