The Next Generation Grid Kostas Tserpes, NTUA Beijing, 22 of June 2005

NextGRID Project Integrated Project Grid Based Systems for Complex Problem Solving Project Start Date: 1 September 2004 Duration: 36 months

Outline Vision Goals & Objectives of NextGRID Consortium Process Specific Areas addressed by NextGRID Topics of Potential Interest

NextGRID Vision An architecture for Next Generation Grids which will enable its widespread use by research, industry and the ordinary citizen thus creating a dynamic market place for new services and products.

NextGRID Goals Develop architectural components that will lead to the emergence of the Next Generation Grid. Prepare the way for the broader use of Grid technologies and their widespread adoption by organisations and individuals from the business and public domains. Improve the technology in key areas such as security, development of applications, interoperability, quality of service and robustness. Contribute to the standards which are essential if Next Generation Grids are to succeed.
