The term “the grid” has emerged in the mid 1990s to denote a proposed distributed computing infrastructure which focuses on large-scale resource sharing, innovative applications, and high-performance orientation [Foster et al., 2001 ]. The grid concept is motivated by a real and specific problem – the coordinated resource sharing and problem solving of dynamic, multi-institutional virtual organizations. The sharing is not primarily a file exchange but rather a direct access to computing resources, software, storage devices, and other resources, with a necessary, highly controlled sharing rule which defines clearly and carefully just what is shared, who is allowed to share, and the conditions under which sharing occurs. A set of individuals and/or institutions defined by such sharing rules forms what we call a virtual organization (VO).
