Abstract

A major challenge in task scheduling is the availability of resources In a heterogeneous environment, where processors operate at different speeds and are not continuously available for computation, achieving a better make-span is a key issue The existing algorithm SSAC has proved to be a good trade-off between availability and responsiveness while maintaining a good performance in the average response time of multiclass tasks But the makespan may be influenced due to load imbalance In this paper we proposed approach try to further optimize this scheduling strategy by using quantum-behaved particle swarm optimization And compared with SSAC and MINMIN in the simulation experiment; results indicate that our proposed technique is a better solution for reducing the makespan considerably.
