A Comparative Analysis between EGEE and GridWay Workload Management Systems ⋆

By J. L. Vázquez-poletti, E. Huedo, R. S. Montero and I. M. Llorente


Abstract. Metascheduling is a key functionality of the grid middleware in order to achieve a reasonable degree of performance and reliability, given the changing conditions of the computing environment. In this contribution a comparative analysis between two major grid scheduling philosophies is shown: a semi-centralized approach, represented by the EGEE Workload Management System, and a fully distributed approach, represented by the GridW ay Metascheduler. This comparative is both theoretical, through a functionality checklist, and experimental, through the execution of a fusion plasma application on the EGEE infrastructure.
