Empowering a Flexible Application Portal with a SOA-based Grid Job Management Framework

There exists today a number of web-based portals and Grid middlewares that support the submission of jobs to Grid resources. A majority of these portals are tightly coupled with the underlying middleware, and rarely provide user interfaces customized to the end-user applications. The Lunarc Application Portal is a Grid portal that supports the development of customized user interfaces for Grid jobs. The Grid Job Management Framework is an application toolkit providing middleware-independent job management. This work describes an integration project combining these two architectures to provide a Grid portal that supports customization of application user interfaces and uses multiple middlewares in a flexible, robust, and loosely coupled way. The integration architecture is presented together with brief introductions to the two systems involved. Finally a performance analysis is performed.
