Research and Technological Development for an International Data Grid

Objetivo

The DATAGRID project will develop and implement a large-scale data-oriented computational grid. This will allow distributed data-intensive scientific computing models, drawn from three scientific disciplines, to be demonstrated on a worldwide testbed. The project will develop the necessary middleware software, in collaboration with some of the leading centres of competence in Grid technology, leveraging practice and experience from previous and current grid initiatives in Europe and elsewhere. The project will complement, and help to coordinate at a European level, several on-going national data grid projects. The testbed will use advanced research networking infrastructure provided by another Research Network initiative. The project will extend the state of the art in international, large-scale data-intensive grid computing, providing a solid base of knowledge and experience for exploitation by European industry.

Objectives:
The objective of this project is to enable next generation scientific exploration, which requires intensive computationand analysis of shared large-scaled databases, from hundreds of TeraBytes to PetaBytes, across widely distributedscientific communities. We see these requirements emerging in many scientific disciplines, including physics, biology, and earth sciences. Such sharing is made complicated by the distributed nature of the resources to beused, the distributed nature of the communities, the size of the databases and the limited network bandwidthavailable. To address these problems we propose to build on emerging computational Grid technologies to establisha research Network that will enable the development of the technology components essential for the implementationof a new worldwide Data Grid on a scale not previously attempted.

Work description:
The structure of the programme of work is as follows:
- WP1 Grid workload Management, WP2 Grid Data Management, WP3 Grid monitoring Services well defined parts of the Grid middleware. Each of these can be viewed as a small project itself.
- WP6 Integration Testbed - Production Quality International Infrastructure is central to the success of the project. It is this workpackage which will collate all of the developments from the development workpackages (WPs 1 - 5) and integrate into successive software releases. It will also gather and transmit all feedback from the end -to-endapplication experiments back to the developers thus linking development, testing, and user experiences.
- WP7 Network Services will provide testbed and experiment workpackages with the necessary infrastructure to enable end-to-end application experiments to be undertaken on the forthcoming European Gigabit/s networks.- WP8 High Energy Physics Applications, WP9 Earth Observation Science Application, and WP10 BiologyScience Applications will provide the end-to-end application experiments, which test and feedback their experiencesthrough the testbed workpackages to the middleware development workpackages.
- WP11 Information Dissemination and Exploitation and WP12 Project Management will ensure the active dissemination and results of the project and its professional management.Each of the development workpackages will start with a user requirements gathering phase, followed by an initial development phase before delivering early prototypes to the testbed workpackage. Following the delivery of these prototypes a testing and refinement phase will continue for each component to the end of the project.

Milestones:
Project Month 12: deployment of core service testbed on multiple test-sites.
Project Month 24: delivery of complete infrastructure.
Project Month 36: demonstration of distributed science with three different classes of applications.
