A grid is large-scale virtual organization which solves complex scientific and compute-intensive problems. As grid technique is growing rapidly in recent years, large-scale grid systems appear to provide the capability of flexible, secure, coordinated resource sharing, and problem solving among dynamic virtual organizations. These systems consequently are required to manage a large amount of related resources. In particular, the shared grid resources can vary from plain desktop systems to clusters and from storage devices to large datasets, even grid service could be seen as an extension of grid resource.
