Graphical Framework for Grid Interactive and Parallel Applications

Considering how complex Grid technology is, it is essential to provide adequate support on users' level in order to simplify interaction and attract users. Intuitive and easy-to-use graphical user interfaces could be critical for the useful- ness of the whole infrastructure and may play a significant role within successful stories. We would like to present the int.eu.grid approach to a Migrating Desktop product that brings the grid interactive services to a users desktop. The Migrating Desktop as the framework for grid applications aims at providing a unified and intuitive graphical work environment that allows users to control sophisticated in- teractive services, access Grid resources, run sequential and parallel jobs - using both batch and interactive paradigms. The Migrating Desktop provides a front-end for embedding some of the application mechanisms and interfaces, and it allows the user to have virtual access to Grid resources. Generic API for applications based on the OSGi specification provides mechanisms for the job submission phase, inter- action with an application and remote visualization of the results which assemble the powerful platform for the Grid environment.
