SJF CPU Scheduling Program in C++
What is the quickest scheduling of jobs?
The job or process scheduling method that adheres to the non-preemptive scheduling discipline is called shortest job first scheduling. In this case, the scheduler chooses the job or process from the waiting list with the shortest completion time and assigns the CPU to it. Because SJF is more optimal than FIFO and decreases average wait times, which will enhance throughput, it is preferred over FIFO.
Both preemptive and non-preemptive SJF algorithms are possible. Shortest-remaining-time-first scheduling is another name for preemptive scheduling. The new process emerges in the preemptive method while the existing process is still running. The scheduler will prevent the execution of the process with the shorter burst time if the burst of the newly incoming process is smaller than the burst time of the current process.
What is Turn Around, Wait, and Completion time?
