The UKNational Grid Service
Summary
• NGS Overview– Goals– Status– Use
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
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.

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)
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
