: : ABSTRACT

Currently, Grid computing is facing a "Grid interoperability contradiction". While Grid addresses interoperability over heterogeneous resources, we now see major interoperability and portability problems between different Grids. As a result, Grid developers are constantly recreating the basics, leading to slow progress in the implementation of fundamental Grid services, which in turn makes the development of portable high-level Grid applications immensely difficult.

Motivated by this contradiction, this presentation focuses on the development of standards-based infrastructure components for Grid resource and project management that contribute to a healthy Grid ecosystem that is not tied to particular Grid middlewares. The approach will be illustrated by ongoing development projects like the SweGrid Accounting System (SGAS), the Decentralized Grid-wide fairshare scheduling system (FSGrid), a Decentralized, cross-middleware Grid Job Submission Service (JSS), a multi-level Grid Job Management Framework (GJMF), and a Generic Grid Workflow Execution Service.
