Estimation of Ready Queue Processing Time Under ... - CORE
Estimation of Ready Queue Processing Time Under Systematic Lottery Scheduling Scheme . By Anjali Jain and D. Shukla. Abstract. This paper presents a scheduling scheme which provides lottery tickets (containing random numbers) to each process in the ready queue. The CPU has a unit to draw random numbers, whenever a scheduling decision has to be ......
 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...
Multilevel feedback queue - Wikipedia
Process scheduling. Unlike multilevel queue scheduling algorithm where processes are permanently assigned to a queue, multilevel feedback queue scheduling allows a process to move between queues. This movement is facilitated by the characteristic of the CPU burst of the process. If a process uses too much CPU time, it will be moved to a lower-priority queue....
