Abstract

QoS (quality of service) has become a hot topic of research in service-oriented grid environment. The key question of embedding multidimensional QoS into task scheduling and RMS (resource management system) evaluation is to find a scheme to integrate multiple QoS metrics. In this paper, measurement model of grid QoS is proposed to integrate multiple QoS metrics. By using this model, multi-dimensional QoS scheduling heuristics is put forward. Finally, two simulation experiments are conducted: one is to make a comparison between traditional Min-Min and multi-dimensional QoS guided Min-Min; another is to apply measurement model to evaluate the performance of grid RMS. It is indicated that the measurement model can integrate multiple QoS metrics effectively and multi-dimensional QoS scheduling can enhance the performance of grid environments remarkably.
