Abstract: Initial work in the Grid ENabled Integrated Earth system model (GENIE) project involved a series of parameter sweep experiments using a Grid infrastructure consisting of a flocked Condor pool, a web service oriented data management system and a web portal. In this paper we introduce the Imperial College E-Science Networked Infrastructure (ICENI) Grid middleware, and describe how it can be used to increase the efficiency of GENIE parameter sweep experiments. We perform several experiments using a combination of different computational resources and different job deployment mechanisms. Our results suggest that ICENI does not produce any significant overhead in the sojourn time of a GENIE parameter sweep experiment and can promote the sharing of computational resources between institutions.
