CS 3733 Operating Systems, Fall 2001 Assignment 2 Comments

The assignment was graded on a basis of 30 points.
The first two parts were 5 points each and the last two parts were 10 points each.

1. The simulator ignores the context switch time.
2. CPU utilizations of 99.3% and 99.6% are close enough that you should not say that one is better than another.
3. If the duration of a process is shorted than the CPU burst, the actual burst will be shortened so that the process has the correct duration.
4. It does not make sense to have a duration shorter than the CPU bursts.
5. Time in the simulator has no dimensions. You should not assume it is in ms.
6. Absolute number of the quantum are meaningless, other than in comparison to other times of the processes, such as CPU burst times.
7. An experiment cannot show that any of the statements in Part 3 are true.
8. In Part 3 you must indicate why you agree or disagree with the statement.
9. Processes do not have quantums, algorithms do. Processes have CPU bursts.
10. Don't use the expression "smaller process" unless you explain what you mean. This usually refers to the amount of memory needed by the process.
