2. Summary NGS Overview –Goals –Status –Use

3. Goals for NGS Provide coherent electronic access for UK researchers to all resources and facilities that they require to carry out their research. –independent of location of resource or researcher. –Common/standard Interfaces –Common/standard procedures Services support the interface and applications use it Goal can not be achieved by NGS alone –NGS will collaborate with Resources and Resource providers Users –Researcher identity and authorisation will be established through standard institutional mechanisms, – Close integration with international partner infrastructures

5. NGS partnership programme Goals: Increase the range and depth of services and resources that NGS can offer to its users by enlisting partners Provide leadership and guidance to sites wanting to put their resources on the Grid by defining NGS compatibility and certifying compliant sites Two levels of partnership An NGS Affiliate is a site certified to be NGS-compatible. –An NGS Partner is a site that offers significant resources or services to NGS users.

9. Applications: 1 Text mining Lattice Boltzmann Molecular Dynamics substrate complex product complex ADP ATP

10. Astronomy Applications: 2 Systems Biology Neutron Scattering Econometric analysis Climate modelling

11. Applications: 3 Many, but not all, applications cover traditional computational sciences –Both user and pre-installed software Several data focused activites Common features are –Distributed data and/or collaborators Not just pre-existing large collaborations – Explicitly encourage new users – Common infrastructure/interfaces Other Applications: nano-particles protein folding ab-initio protein structure prediction radiation transport (radiotherapy) IXI (medical imaging) Biological membranes Micromagnetics Archeology Text mining Lattice QCD (analysis) Astronomy (VO services)

12. Conclusion National Grid Service has now been operational for 18 months –Funded through to 2009 and recognised as strategically important Focused on Services not Technology Ultimate success will be determined by how many resource and users support the interfaces
