Scheduling Algorithms Exponential Queues • Popular in interactive systems • A single queue is maintained for each priority level • A new process is added at the end of the highest priority queue – It is alloted a single time quantum when it reaches the front • If it yields the CPU within the time quantum, it is moved to the rear ......
 CPU Scheduling
5 Round Robin (RR) n Each process gets a small unit of CPU time (time quantum).After time slice, it is moved to the end of the ready queue. Time Quantum = 10 - 100 milliseconds on most OS n n processes in the ready queue; time quantum is q n each process gets 1/n of the CPU time in q time units at once. n no process waits more than (n-1)q time units. n each job gets equal shot at the CPU...

end of the ready queue Suppose N processes in ready queue and time quantum is Q ms: Each process gets 1/N of the CPU time In chunks of at most Q ms What is the maximum wait time for each process? No process waits more than (n-1)q time units Lec 3. Operating Systems. 15 Round Robin (RR) Scheduling. Round Robin Scheme...
 Processes and Threads - Binghamton
Instead of running jobs to completion, RR runs a job for a time slice (scheduling quantum) and switches to the next job in the ready queue; repeatedly does so until jobs are finished. Time slicing – length of time slice = multiple of timer-interrupt period. SJF response time = 5. RR response time = 1...

Round Robin (RR) Scheduling Each process gets a small unit of CPU time (time quantum), usually 10-100 milliseconds. After this time has elapsed, the process is preempted and added to the end of the ready queue. If there are n processes in the ready queue and the time quantum is q, then each process gets 1/n of the...
