The Multi-level Feedback Queue (MLFQ) sched-uler was ?rst described by Corbato et al in 1962 [C+62] in a systemknown as the Compatible Time-Sharing System (CTSS) and this workalong with later work on Multics led the ACM to award Corbato itshighest honor theTuring Award
Multilevelfeedback queues require parameters to de?ne the number of queuesthe scheduling algorithms for each queue the criteria used to moveprocesses between queues and so on These algorithms are thus really sets of algorithms (for example theset ofRRalgorithms for all time slices and so on)
Multi-Level Feedback Scheduling • A scheduling method for exploiting past behavior – First used in Cambridge Time Sharing System (CTSS) – Multiple queues each with different priority » Higher priority queues often considered “foreground” tasks – Each queue has its own scheduling algorithm

Multilevel Feedback Queues (MLFQ) • Multilevel feedback queues use past behavior to predict the future and assign job priorities => overcome the prediction problem in SJF • If a process is I/O bound in the past it is also likely to be I/O bound in the future (programs turn out not to be random )
Multilevel Queue Scheduling Operating Systems 26 Multilevel Feedback Queue A process can move between the various queues; aging can be implemented this way Multilevel-feedback-queue scheduler
What is multilevel feedback queue scheduling?
Multilevel feedback queue (MLFQ) scheduling uses a system of queues, each designated a different priority. Each queue is assigned a different quantum time for Round-Robin (RR) scheduling.
How does a multilevel queue-scheduling algorithm work?
To further understand how this scheduling operates, let’s look at an example of a multilevel queue-scheduling algorithm with five queues: Every queue would take precedence over queues with lower priorities. Until the high-priority queues are empty, no process may proceed.
Is there starvation in multilevel feedback queue?
In multilevel feedback queue there is a large chance of starvation for the processes at the lowest priority queues. As the gamers may achieve the ability to remain in the highest priority queue as shown in the figure below,
Is there an algorithm for feedback scheduling?
A simple yet illustrative feedback scheduling algorithm is given. From a programming perspective, we describe how to modify the implementation of control tasks to facilitate the application of feedback scheduling.
