To not let any process wait longer than 500 ms, a system developer programs the Round Robin procedure with a dynamic time quantum size. With ‘n’ processes ready, the time quantum Q is set to 500 ms/n. What do you think of this scheduling strategy? (In which situations is this strategy feasible, and when is it not? Are there edge cases?) Explain your reasoning.
Table 1. 4 processes arriving shown in Operating System Scheduling PDF for Shortest Job Next, non- preemptive Process Arrival Times Execution Times Service Times sequence Wait Times calculations PO 0 12 P1 21 9 P2 41 6 P3 6 3 Total wait time = ? Here the 4 processes of the PDF are repeated in Table 1, with arrival times changed to 0, 2, 4, and 6 respectively. Also, the execution times are changed to 12, 9, 6, and 3. You will be asked to fill table 1 with the numbers like the service times (when is each process serviced), the sequence of executions of these 4 processes in part (a) and part (b) below. Also, you will compute the total wait time. Note for FCFS, it is 1, 2, 3, 4 for P0, P1, P2, and P3; • for the SJN or Shortest Job Next with non-preemptive, PO is #1, P1 may not be #2; for SRT, or shortest remaining time, the preemptive version of SJN, PO is #1, but after 2 time units when P1 comes, P1 kicks out PO since its execution time is 4 < 9- 2 = 7; and P1 may be preempted by P2 later…
In the following resource allocation graph, are the processes deadlocked? If “yes” explain why and state which processes are involved in deadlock. If “not” explain why.
Please help with this question!!
Let the processes P1, P2, P3, P4, and P5 be given. They arrive in the system at the same time in this order. The processes have the attached service times (in time units) and priorities. For each of the scheduling methods (First Come, first served (FIFO), Shortest Job First, Round Robin, and Priority Scheduling), specify the execution order of the processes and the average execution time (average turnaround time) for all processes. First, determine and state the execution times of the individual processes and then calculate the average value. Note: • For Shortest Job First, If the required service time (CPU time) is the same for two or more processes, use First Come, first served to resolve the conflict. • For Round Robin, the time quantum q = one time unit. • For Priority Scheduling, low integer priority values signify high priorities, with O being the highest possible priority. If multiple processes have the same priority, use First Come, first served to resolve the conflict. Also,…
When a stalemate occurs, those processes should be terminated, with the following outcomes:
