519 Improving Energy- Efficiency of Computational Grids via Scheduling Ziliang Zong South Dakota School of Mines and Technology, USA Xiaojun Ruan Auburn University, USA Adam Manzanares Auburn University, USA Kiranmai Bellam Auburn University, USA Xiao Qin Auburn University, USA Chapter 22 AbsTRACT High performance Grid platforms and parallel computing technologies are experiencing their golden age because of the convergence of four critical momentums: high performance microprocessors, high- speed networks, free middleware tools, and highly increased needs of computing capability. We are witnessing the rapid development of computational Grid technologies. Dozens of exciting Grid infra- structures and projects like Grid-tech, Grid Portals, Grid Fora, and Commercial Grid Initiatives are being built all over the world. However, the fast growing powerconsumption of data centers has caused serious concerns for building more large-scale supercomputers, clusters, and Grids. Therefore, design- ing energy-efficient computational Grids to make them economically attractive and environmentally friendly for parallel applications becomes highly desirable. Unfortunately, most previous studies in Grid computing primarily focus on the improvement of performance, security, and reliability, while completely ignoring the energy conservation issue. To address this problem, we propose a general architecture for building energy-efficient computational Grids and discuss the potential possibilities for incorporating power-aware techniques to different layers of the proposed Grid architecture.
