Production Grids are becoming widely utilized by the e-Science community to run computation and data intensive experiments more efficiently. Unfortunately, different production Grid infrastructures are based on different middleware technologies, both for computation and for data access. Although there is significant effort from the Grid community to standardize the underlying middleware, solutions that allow existing nonstandard tools to interoperate are one of the major concerns of Grid users today. This paper describes the generic requirements towards the interoperation of Grid data resources within computational workflows, and suggests integration techniques that allow workflow engines to access various heterogeneous data resources during workflow execution. Reference implementations of these techniques are presented and recommendations on their applicability and suitability are made.

“…This workflow level integration now allows the seamless interoperation of SRB catalogues, GridFTP file systems and EGEE storage elements (based on SRM) at the level of P-GRADE workflows. Figure 6 illustrates a workflow simulating urban car traffic [41]. As it is shown on the figure, jobs of the workflow are running in different grids (US OSG, UK NGS, EGEE) and utilise data resources based on different technologies (SRB, SRM, GridFTP, local) from these different grids .…”

Abstract-The lack of widely accepted standards and the use of different middleware solutions divide today's Grid resources into non-interoperable production Grid islands. On the other hand, more and more experiments require such a large number of resources that the interoperation of existing production Grids becomes inevitable. This paper, based on the current results of grid interoperation studies, defines generic requirements towards the workflow level interoperation of grid solutions. It concentrates on intra-workflow interoperation of grid data resources, as one of the key areas of generic interoperation, and describes through an example how existing tools can be extended to achieve the required level of interoperation.
