ABSTRACT
The proliferation of the Internet and the availability of powerful computers and high-speed networks as low-cost commodity components are changing the way computing is done today. The interest in coupling geographically distributed computational resources is also growing for solving large-scale problems, leading to what is popularly called Grid Computing. Grids enable the sharing, selection, and aggregation of suitable computational and data resources for solving large-scale data intensive problems in science, engineering, and commerce [1-3].
