Analysis and Performance Assessment of CPU Scheduling Algorithms in Cloud using CloudSim

Abstract

Scheduling refers to a set of policies and mechanisms to control the order of work to be performed by a computer system. CPU is by far the most important resource of the computer system. Recent advances in software and architecture of the system increased the complexity of the processing as the computing is now distributed and parallel. Job scheduling is complex in this environment. The VM (Virtual Machine) can use a distinctive VCPUs (Virtual CPU) running queue for each physical CPU, which is referred to Partition Queue Model (PQM). As a contrast, a Sharing Queue Model (SQM) of CPU scheduling algorithm can be used. This paper is analyzing and evaluating the performance of various CPU scheduling in cloud environment using CloudSim.
