MLFQ

Here is a partial Gantt chart for the processes above:

MLFQ Multilevel Feedback Queue (preemptive - absolute priority in higher queues) Queue 1 uses RR scheduling with Tq 5 Queue 2 uses RR scheduling with Tq 10 Queue 3 uses FCFS All processes enter first queue 1. If time quantum (Tq) expires before CPU burst is complete, the process is downgraded to next lower priority queue. Processes are not downgraded when preempted by a higher queue level process. Once a process has been downgraded, it will not be upgraded. sumptions: 1. All processes are activated at time 0 2. Assume that no process waits on LO devices. 3. After completing an IO event, a process is transferred to the ready queue. 4. Waiting time is accumulated while a process waits in the ready queue. 5. Turnaround time is a total of (Waiting time) + (CPU burst time) + (IO time) 6. Response time is the first measure of waiting time from arrival at time 0 until the first time on the CPU MLFQ Multilevel Feedback Queue (preemptive - absolute priority in higher queues) Queue 1 uses RR scheduling with Tq 5 Queue 2 uses RR scheduling with Tq 10 Queue 3 uses FCFS All processes enter first queue 1.
