- Four processes arrive at the same time with their priorities, execution times and I/O times given in the table below. Assuming a Round-Robin Scheduling works with a quantum time of 3, but the scheduler selects the process with highest priority from the queue (NOT those arrived earliest), other than currently pre-empted process, at each turn; a-)Draw the timeline for CPU- and I/O- bursts for these processes b-)Calculate average turn-around timeReal-time scheduling: In a system consisting of two processes, P1 and P2, suppose process P1 has a period p1 of 50, an execution time t1 of 25, and a deadline that matches its period (50). Further, suppose that P2 has a period p2 of 75, an execution time t2 of 30, and a deadline that matches its period (75). Is this real-time system schedulable under rate-monotonic scheduling? Explain your answer using the concept of overall CPU utilization and schedulability.Given three processes (process id P0, P1, P2 respectively) with compute time bursts 6, 2, and 8 units. All processes are available at t=0. Consider the shortest-job-first scheduling algorithm and find the sequence in which the processes will be scheduled.
- Consider the following set of processes. Process BurstTime Priority Arrival P1 30 20 0 P2 5 25 5 P3 15 20 12 P4 10 30 48 Assume that the CPU is idle at time 0 and that processes are being scheduled using a preemptive, priority-based, round-robin scheduling algorithm. Each process is assigned a numerical priority, with a higher number indicating a higher relative priority. For processes with the same priority, a round-robin scheduler will be used with a time quantum of 10 units. If a process is preempted by a higher-priority process, the preempted process is placed at the end of the queue. a.What is the turnaround time for P3? Give your answer as an integer. b. What is the waiting time for P1? Give your answer as an integer. c. Indicate whether the processes run concurrently. 1P1 and P3 2P2 and P3 3P4 and P3 d. How many times does a context switch from P1 occur? Give your answer as an integer.consider the following set of processes with the length of the cpu burst time in given ms: process burst time arrival time p1 8 0.00 p2 4 1.001 p3 9 2.001 p4 5 3.001 p5 3 4.001 a) draw four gantt chart illustrtaing the exaction of these processes using FCFS SJF PRIORITY and RR (quantum=2) scheduling b) also calculate waiting time and turnaround time for each scheduling algorithmsConsider the following set of six processes, with the arrival times, CPU burst time (in milliseconds), and priority. process arrival time burst time priority P1 22 10 3 P2 8 4 2 P3 28 12 6 P4 10 8 1 P5 35 6 5 P6 8 20 4 (a) Draw four Gantt charts that illustrate the execution of these processes using the following scheduling algorithms: FCFS, SJF, preemptive priority (a smaller priority number implies a higher priority), and RR (quantum= 8).(b) Compute the average wait time in each of the scheduling algorithms in part (a)?
- Consider the following five processes each having its own unique execution time and arrival time Process Arrival Time Execution Time A 0 6 B 3 2 C 5 4 D 7 6 E 10 3 Draw a timeline and compute the average turnaround time and average waiting time for reach of the scheduling algorithms below: 1.FCFS 2.Round Robin (time slice = 3) 3. SRT 4. SJFA real-time system executing four different periodic tasks Ti(p,t) is given, with p and t representing the period and the execution time of the task, respectively. Each task's deadline matches its period p. The system is executing the following set of tasks: S = {T1(10,2), T2(4,1), T3(10,3), T4(7,1)}. Is this real-time system schedulable under Rate-Monotonic (RM) scheduling? Is this real-time system schedulable under Earliest Deadline First (EDF) scheduling? Explain your answers using the concept of overall CPU utilization.Consider the FCFS, SJF, and RR (quantum = 8 milliseconds) scheduling algorithms for this set of processes. Process Burst Time P1 8 P2 25 P3 3 P4 7 P5 11 The processes are assumed to have arrived in the order P1, P2, P3, P4, P5, all at time 0. a) Draw Gantt charts that illustrate the execution of these processes using the following scheduling algorithms: FCFS, SJF, and RR. b) What is the waiting time of each process for each of these scheduling algorithms? c) Which of the algorithms results in the minimum average waiting time (overall processes)? d) Derive the Need (max-Alloc) matrix. It should be presented like the Allocation or Maximum matrices above. e) If the request from process P1 arrives for (0,1,2,0), can the request be granted? Why?
- Consider the following set of processes (a smaller priority number implies a higher priority). The processes are assumed to have arrived in the order P1, P2, P3, P4, P5 all at time 0. Process Priority Burst Time P1 1 20 P2 3 25 P3 4 25 P4 2 15 P5 5 30 Draw four Gantt charts that illustrate the execution of these processes using the following scheduling algorithms: FCFS, SJF (if two jobs have the same burst time, schedule them following priority), and non-preemptive priority.ProcessBurst Time Priority Arrival TimeP1 10 3 0P2 1 1 0P3 2 5 0P4 1 4 0P5 5 2 0For the set of processes directly above, draw a Gantt chart for the FCFS Scheduling Algorithm.Six batch jobs arrive almost at the same time in the following order: p1;p2; : : : ;p6.
