Question 3 Suppose that the following processes arrive for execution at the times indicated. Each process has the shown priorities and will run for the amount of time listed (all times are in ms) Process Arrival Time Burst Time Priority Queue P1 15 3 P2 20 3 P3 20 20 2 P4 25 10 2 P5 30 2 P6 35 15 1 To schedule the execution of these process, a preemptive multi-level queue scheduler is designed to apply the following policy at each decision instant (namely whenever a new process arrives and whenever a burst completes execution) : • Serve the process at the highest priority queue first • If two processes are in the same queue: . If they have different remaining time, follow the SRTF policy • If they have same remining time, follow a RR policy (slice time = 2 ms) Given the above: 1. Show the scheduling order of the bursts using a Gantt chart.

Part I Assume that the ready queue has just received for processes: P1, P2, P3, P4, in that order. All at time 0. The CPU execution times for these processes are as follows: Process Execution Time P1 P2 P3 P4 13 8 15 6 Draw the Gantt chart and calculate the metric listed in parentheses for each of the following scheduling algorithms: 1. First Come, First Served (Total Wait Time) 2. Shortest Job First (Total Wait Time) 3. Round Robin, with a time quantum of 5 ms (Total Wait and Response Times) Part II Now assume that P1 arrives in the ready queue at time 0, P2 arrives at time 4, P3 arrives at time 10, and P4 arrives at time 20.

Concurrent Processes / Monitors select which is true options: a CV (condition variable) queues in a monitor store suspended processes waiting on the corresponding condition. b The "Signal and Wait" approach (Hoare semantics) leads to more efficient implementation and reduces the number of context switches. c Two or more processes can be active in the same monitor simultaneously. d When the "Signal and Continue"-approach (Mesa semantics) is applied, the signaling process P continues executing. e The monitor-based solution to the Dining-Philosophers problem discussed in class is restricted to 5 philosophers.
