A grid hosting system for multiple virtual organizations

Abstract

Virtual Organizations (VOs) are dynamic and possibly overlapping groups of resources and users in the Grid. With the current development of Grid technologies, it is a still a major challenge to build and run virtual organizations. Firstly, from an administrative perspective, it is difficult to manage dynamic and overlapping virtual organizations. Secondly, for users it is cumbersome to work in multiple virtual organizations. To address these issues, this thesis proposes a concept of providing a VO hosting service and presents a software package called GHOSTS (Grid HOSTing System). The system employs a simple Virtual Organization model and it can host multiple VOs with dynamic and overlapping sets of resources and users. It is based on a centralized server that integrates VO management and Portlet-based Grid portals. This solution can hide complexity of VO management and also provides an easy-to-use working environment for using Grid resources.
