Abstract: CASTEP is an application which uses the density functional theory to calculate physical properties of materials and molecules. This paper investigates the execution mechanisms for running CASTEP applications using grid resources. First, a lightweight execution environment is developed for CASTEP, so that the CASTEP applications can be run on any grid computing resource even without the CASTEP server being installed. Then, two execution mechanisms are developed and implemented. One is based on Condor's file transfer mechanism, and the other based on independent data servers. Both mechanisms are complete with the GridSAM job submission and monitoring service. Finally, the performance of these mechanisms is evaluated by deploying them on CamGrid, a university-wide grid at the University of Cambridge. These presented execution mechanisms also offer excellent opportunities to be applied to other e-science applications.
