Shortest Job First(SJF) Scheduling Algorithm Code in C

Splet20. jan. 2024 · Shortest Job First (SJF) is a Scheduling Algorithm where the process are executed in ascending order of their burst time, that is, the process having the shortest burst time is executed first and so on. The processor knows burst time … SpletThe waiting time of the first element is always zero. So, the remaining waiting time is calculated by using two for loops. So the inner for loop is controlled by another for loop … SpletThe CPU scheduling algorithm Shortest Job First ( SJF ), allocates the CPU to the processes according to the process with smallest execution time. SJF uses both preemptive and non-preemptive scheduling. The preemptive version of SJF is called SRTF (Shortest Remaining Time First).

Splet07. mar. 2024 · Computer Architecture SJF is a Shortest job first or shortest job next scheduling algorithm that picks the waiting process which has the smallest execution time to be executed next. SJF scheduling algorithm is also called as a Greedy Algorithm. SJF Scheduling algorithm is a non-preemptive algorithm. SpletProgram Explanation. 1. Initialize two array pid [] and bt [] of size 15. 2. Ask the user for number of processes n. 3. Ask the user for process id and burst time for all n processes and store them into pid [] and bt [] respectively. 4. Calculate waiting time of each process by the formula wt [i] = wt [i-1] + bt [i-1].
