Abstract. The complexity of simultaneously providing customized user interfaces and transparent Grid access has led to a situation where current Grid portals tend to either be tightly coupled to specific middlewares or only provide generic user interfaces. In this work, we build upon the methodology of the Grid Job Management Framework and propose a flexible and robust 3-tier integration architecture that decouples application interface customization from Grid job management. Furthermore, we illustrate the approach with a proof of concept integration of the Lunarc Application Portal, which here serves as both a framework for the creation of application-oriented user interfaces and a Grid portal, and the Grid Job Management Framework, a framework for transparent access to multiple Grid middlewares. The loosely coupled architecture facilitates creation of sophisticated user interfaces customized to enduser applications while preserving the middleware-independence of the job management framework. The integration architecture is presented together with brief introductions to the integrated systems, and a system evaluation is provided to demonstrate the flexibility of the architecture. 1
