The UK
National Grid Service

The Mission of the
NGS
To provide coherent electronic access for
UK researchers to all computational and
data based resources and facilities
required to carry out their research,
independent of resource or researcher
location
The Vision of the NGS
• National infrastructure services which allow researchers to:
– systematically create, process, preserve and publish digital
information;
– easily navigate through the available resources;
– be confident in the quality of the services available;
– tie into international efforts
• To achieve this, the NGS will
– Lead the deployment of a common grid infrastructure
– Promote common open standards
– Through the NGS Partnership programme, integrate
services to access a growing number, scale and variety of
resources
• A production Service
The NGS Today
NGS-2
• Each Core Site
• Thin compute node
– 48 dual socket dual core AMD Opteron 280
– 8GB memory
• Fat compute node
– 8 quad socket dual core AMD Opteron 280
– 32GB memory
• Storage
• Leeds and Oxford
– 15 TB Fibre SAN
– 3 dual socket dual core AMD Opteron 280 servers
• Manchester and CCLRC
In Total
1024 Cores, 2.5TB
– 60 TB Fibre SAN
– 8 dual socket dual core AMD Opteron 280 servers memory, 150TB disk,
100kW power
Application
Repository
Access to NGS
• Evolving models
• Several agenda’s
– Encourage new users, support collaborative activities, enable
research
• How do users get access
– Lightweight “peer review” (e-science certificate)
– Individual users -> projects
• What do users get
– Access to resources (that they are authorised to use or pay for)
– Access to core services
– “free” allocations on core nodes (and some partners)
• Time limited allocations
• No guarantees beyond each re-application - best efforts
• Opportunity to build a collaboration/case/support
– Many users news to the game, e.g. students
Conclusions
• National Grid Service in operation since 2004.
• Key strategic component
• JISC, EPSRC, CCLRC
• Inclusive infrastructure, not exclusive club
• Look forward to working with a increasingly wide
range of research projects

International Identity
• The NGS operates the UK e-Science Certification
Authority (CA) providing X.509 certificates for the UK eScience community.
• It is the CA for Grid and e-Science activities in the UK,
meaning it is internationally approved to issue
certificates to people and hosts in the UK.
• Identity certified by network of Registration Authorities
throughout the UK.
