UDC 004.051 A simple GRID system model for estimating a job scheduling algorithm impact on power consumption I.L. Kaftannikov, South Ural State University, Chelyabinsk, Russian Federation, kil@comp.susu.ac.ruK.M. Khankin, South Ural State University, Chelyabinsk, Russian Federation, hc@comp.susu.ac.ruAbstractThe model of GRID system including two clusters is described. Model is created by simulation in AnyLogic. The main purpose of the model is to estimate the impact of GRID broker scheduling algorithm on GRID power consumption. Model displays task scheduling process and counts average power consumption by task, average local queues length, average waiting time in queues and probability distribution for average waiting time. The scheduling algorithm that makes power consumption lower is described and compared with algorithm of queue length equality. Described algorithm performs scheduling by the criterion of graphic processing unit presence on the cluster and implementation for the GPU presence in task.
