Priority Scheduling
Aim To schedule snapshot of processes queued according to Priority scheduling.
Algorithm 1. 2. 3. 4.
Define an array of structure process with members pid, btime, pri, wtime & ttime. Get length of the ready queue, i.e., number of process (say n) Obtain btime and pri for each process. Sort the processes according to their pri in ascending order. a. If two process have same pri, then FCFS is used to resolve the tie. 5. The wtime for first process is 0. 6. Compute wtime and ttime for each process as: a. wtimei+1 = wtimei + btimei b. ttimei = wtimei + btimei 7. Compute average waiting time awat and average turn around time atur 8. Display the btime, pri, ttime and wtime for each process. 9. Display GANTT chart for the above scheduling 10. Display awat and atur 11. Stop
Result Thus waiting time & turnaround time for processes based on Priority scheduling was computed and the average waiting time was determined.
