Abstract. Existing Distributed Resource Managers (DRMs) lack support for a standard submission language and interoperable interface for describing and launching jobs. This paper presents a standards-based job submission system, GridSAM 1, which utilises Web Services and the Job Submission Description Language (JSDL). GridSAM provides a transparent and efficient bridge between users and existing DRM systems, such as Condor. We demonstrate, through a set of performance results, the small overhead imposed by the GridSAM submission pipeline while improving the overall system throughput and availability. The performance results are gathered from a variety of deployment configurations to exercise the wide-ranging support of GridSAM in terms of launching mechanism, clustering set up and persistence choice.
