CPU Scheduling is the basis of multi-programmed operating system. The scheduler is responsible for multiplexing processes on the CPU. There are many scheduling algorithms available for a multi-programmed operating system like FCFS, SJF, Priority, Round Robin etc. In this paper, the results of the...
Experiment and comparison show that the VRRP outperforms other CPU scheduling algorithms. It gives better evaluation results in the form of scheduling criteria. We have used the deterministic model to compare the different algorithms.doi:10.4236/jcc.2015.34005Pawan Singh...
Non-preemptive SchedulingNon-preemptive scheduling algorithms refer to the class of CPU scheduling technique where once a process is allocated the CPU, it holds the CPU till the process gets terminated or is pushed to the waiting state. No process is interrupted until it runs to completion. ...

Let's take an example where four processes, P0, P1, P2, and P3, have different arrival times in the queue. Based on their priority or burst time, these processes are interrupted and allocated the CPU. Non-Preemptive Scheduling Differences Scheduling Algorithms Lesson Summary Register to view ...

Approximation algorithms Speed-scaling Non-preemptive scheduling 1. Introduction One of the main mechanisms used for minimizing the energy consumption in computing systems and portable devices is the so called speed-scaling mechanism [1], where the speed of a processor may change dynamically. If the...
Unlike the preemptive version that is known to be in P, the non-preemptive version of speed scaling is strongly NP-hard. In this work, we present a constant factor approximation algorithm for it. The main technical idea is to transform the problem into the unrelated machine scheduling problem...
