An optimized round robin cpu scheduling algorithm with dynamic time quantum
CPU scheduling is one of the most crucial operations performed by operating system. Different algorithms are available for CPU scheduling amongst them RR (Round Robin) is considered as optimal in time shared environment. The effectiveness of Round Robin completely depends on the choice of time quantum. In this paper a new CPU scheduling algorithm has been proposed, named as DABRR (Dynamic Avera...
متن کاملModified Round Robin Scheduling Algorithm Using Variable Time Slice
CPU scheduling is the basis of multi-programmed operating systems. The main objective of scheduling algorithms is to reduce the response time, waiting time and to increase the throughput and CPU utilization. Round Robin assumes that all processes are equally important; each receives an equal portion (time slice) of the CPU. This will sometimes affect the performance of CPU. This paper considers...
متن کاملEvaluation of Surplus Round Robin Scheduling Algorithm
In multi-service packet networks the packet scheduling algorithm plays a key role in delivering guaranteed service to different flows. In this article we evaluate surplus round robin (SRR) scheduling algorithm. We apply the Latency-Rate (LR) servers theory in order to obtain bounds on the latency and delay provided by the algorithm. We compare the performance characteristics of SRR with the pop...
متن کاملEstimation of Quantum Time Length for Round-robin Scheduling Algorithm using Neural Networks
The quantum time length is usually taken as a fixed value in all applications that use Round Robin (RR) scheduling algorithm. The determination of the optimal length of the quantum that results in a small average turn around time is very complicated because of the unknown nature of the tasks in the ready queue. The round robin algorithm becomes very similar to the first in first served algorith...
متن کاملAn Optimum Time Quantum Using Linguistic Synthesis for Round Robin Scheduling Algorithm
In Round Robin CPU scheduling algorithm the main concern is with the size of time quantum and the increased waiting and turnaround time. Decision for these is usually based on parameters which are assumed to be precise. However, in many cases the values of these parameters are vague and imprecise. The performance of fuzzy logic depends upon the ability to deal with Linguistic variables. With th...
