This book constitutes the refereed proceedings of the First IEEE/ACM International Workshop on Grid Computing, GRID 2000, held in Bangalore, India in December 2000. The 18 revised full papers presented together with an invited paper and a keynote paper were carefully reviewed and selected for inclusion in the proceedings. The papers are grouped in topical sections on grid resource management, grid middleware and problem solving environments, grid test beds and resource recovery, and application-level scheduling on the grid.
