TUX-INTERO: A Portal for secure interoperation of Grids

摘要

In this paper, we propose TUX-INTERO - a portlet-based Grid portal for integrating existing grid technologies under a common interface and providing reliable services to the users. We have developed a prototype of TUX-INTERO - a grid portal using portlet technology. The paper presents design and development of TUX-INTERO. The requirements for the portal, its design and technology choices lead to the utilization of Globus Toolkit as middleware for connecting global resources, SUN N1 GE6 and Condor as Local Resource Management Systems for connecting local resources and GridSphere as the portal framework. The results demonstrate secure interoperation of grids as TUX-INTERO and TUX-TMS (Thapar University Extensible-Trust Management System) integrates to provide reliable services to the user.
