Experiment Details A Grid based approach, using the reality Grid steering library enables us to launch, monitor checkpoint and spawn multiple simulations Each simulation is a parallel molecular dynamic simulation running on a supercomputer class machine At any given instant, we had up to nine simulations in progress(over 140 processors) on machines at 5 different sites e.g 1X TG-SDSC, 3X TG-NCSA, 3x NGS-OXford 1x NGS-Leeds 1X NGS-RALExperiment Details • A Grid based approach, using the RealityGrid steering library enables us to launch, monitor, checkpoint and spawn multiple simulations • Each simulation is a parallel molecular dynamic simulation running on a supercomputer class machine • At any given instant, we had up to nine simulations in progress (over 140 processors) on machines at 5 different sites: e.g 1x TG-SDSC, 3x TG-NCSA, 3x NGS-Oxford, 1x NGS-Leeds, 1x NGS-RAL
