VAST: A service based resource integration system for Grid Society

Grid and P2P are two different ways of organizing heterogeneous resources. However, the similarity in their target of resource sharing determines that they could be and should be treated together. Reference [4] proposed the concept as well as system model of 'Grid Society', which describes the Grid-P2P mixed environment and demonstrates the similarity between Grid Society and Human Society. Following this idea, we continued by an in-depth analysis of Grid Society environment from systematical aspect and designed a service-based architecture for VAST, a resource integration system. In VAST, Grid and P2P Resource Access Entry assists the Portal to co-schedule resources by providing a set of well-defined service interfaces; DCI, a P2P software system, was also developed to meet the special requirements of Portal; and Portal, coordinator of the whole system, links those two Access Entries and provides a friendly interface to the End Users for controlling and monitoring the submitted jobs. VAST has already been implemented using Java and Web Service technologies, which helps to achieve good portability. Further more, an experiment of parameter sweep application has also been conducted to test the prototype of VAST and through it VAST shows a promising potential for the collaboration of different kinds of resources.
