Weaving computational grids: How analogous are they with electrical grids?

Abstract

Can computational grids make as great an impact in the 21st century as electrical grids did in the 20th? A comparison of the two technologies could provide clues about how to make computational grids pervasive, dependable, and convenient. In this article, we describe how computational grids developed, their layered structure, and their emerging operational model, which we envisage as providing seamless, utility-like access to computational resources. We also attempt to show the similarities and dissimilarities between this system, still in its infancy, and the mature electrical power grid. By identifying quantities and parameters that are analogous between the two grids, we hope that we can ..
