However, it is challenging for researchers to effectively utilize available resources that are under control by independent resource providers as the number of jobs (that should be submitted at once) increase dramatically (as in parameter sweeps or N-body calculations).=0A=0AWe designed a HTCaaS (HTC as a Service) system which aims to provide researchers with ease of exploring a large-scale and complex HTC problems by leveraging Grids, Supercomputers and Cloud. Our contributions include Meta-Job based automatic job split & submission, intelligent resource selection algorithm that automatically selects more responsive and effective resources, pluggable resource interface to heterogeneous computing environment and client application independency through a simple and uniform WS-Interface. We demonstrate the architecture of our system and how it works with several examples.
