SLA-Based Scheduling of Bag-of-Tasks Applications on Power-Aware Cluster Systems

Abstract

Power aware scheduling problem has been a recent issue in cluster systems not only for operational cost due to electricity cost but also for system reliability In this paper we provide SLA based scheduling algorithms for bag of tasks applications with deadline constraints on power aware cluster systems The scheduling objective is to minimize power consumption as long as the system provides the service levels of users A bag of tasks application should finish all the sub tasks before the deadline as the service level We provide the power aware scheduling algorithms for both time shared and space shared resource sharing policies The simulation results show that the proposed algorithms reduce much power consumption compared to static voltage schemes
