An Optimum Multilevel Dynamic Round Robin Scheduling Algorithm
share
The main objective of this paper is to improve the Round Robin scheduling algorithm using the dynamic time slice concept. CPU scheduling becomes very important in accomplishing the operating system (OS) design goals. The intention should be allowed as many as possible running processes at all time in order to make best use of CPU. CPU scheduling has strong effect on resource utilization as well as overall performance of the system. Round Robin algorithm performs optimally in time-shared systems, but it is not suitable for soft real time systems, because it gives more number of context switches, larger waiting time and larger response time. In this paper, a new CPU scheduling algorithm called An Optimum Multilevel Dynamic Round Robin Scheduling Algorithm is proposed, which calculates intelligent time slice and changes after every round of execution. The suggested algorithm was evaluated on some CPU scheduling objectives and it was observed that this algorithm gave good performance as compared to the other existing CPU scheduling algorithms.
