How does a multilevel feedback queue work?
Whereas the multilevel queue algorithm keeps processes permanently assigned to their initial queue assignments, the multilevel feedback queue shifts processes between queues. The shift is dependent upon the CPU bursts of prior time-slices. If a process uses too much CPU time, it will be moved to a lower-priority queue.How does MLFQ prevent starvation?
This is accomplished by adding a second level of feedback to redirect a “safe” amount of CPU time to the lowest-priority queue to prevent starvation of processes in that queue. Multi-tasking operating systems strive keep multiple processes in the computer's main memory in order to keep the processor highly-utilized.Is MLFQ preemptive?
2.7 MLFQ Scheduling (Multi-Level Feedback Queue): Preemptive
Same as MLQ but a process can move among the various queues. Pros: o Very flexible: we can configure the MLFQ scheduler to match a specific system o Automatically classifies processes into I/O bound and CPU bound. Cons: o Very complex to design and implement.- Multi-Level Feedback Queue Scheduling - MLFQS uses multiple queues with priorities, drop- ping CPU-bound jobs that consume their entire quanta into lower-priority queues.
