Three batch jobs, A through E, arrive at a computer center at almost the same time. They have estimated running times of 10, 6, 2, 4 and 8 minutes. Their priorities are 3, 5, 2, 1 and 4 respectively, with 5 being the highest priority.
(a) For each of the following scheduling algorithms, determine the mean turnaround time. Ignore any process switching overhead.
1. Round Robin
2. Priority scheduling
3. First come, First served (run in order 10, 6, 2, 4, 8)
4. Shortest job first
For (a), assume that the system is multiprogrammed, and that each job gets its fair share of the CPU. For (b) through (d) assume that only one job runs at a time, until it finishes. All jobs are completely CPU bound.
