GOSC Roles UK Grid Services
National Services Authentication, authorisation, certificate management, VO management,
security, network monitoring, help desk + support centre. NGS Services
Job submission, simple registry, data transfer, data access and integration, resource brokering, monitoring and accounting, grid management services, workflow, notification, operations centre.
NGS core-node Services CPU, (meta-) data storage, key software
Services to be coordinated with others (eg OMII, NeSC, LCG): Integration testing, compatibility & Validation Tests, User Management,
training
Administration: Policies and acceptable use SLA’s, SLD’s Coordinate deployment and Operations

GOSC + ETF
• Core of GOSC built around experience in deploying and running National Grid Service (NGS)
– Support service
• Important to coordinate and integrate this with deployment and operations work in EGEE, LCG and similar projects.
– e.g. EGEE – low level services, CA, GOC, CERT...
• Focus on deployment and operations, NOT development.

ETF• Registry
– A freely available UDDI implementation has been deployed/tested between 4 sites – Experience passed on to the GRIMOIRES OMII project.
• Secure Flocking of Condor– Condor pools at 4 sites have been flocked together, through firewalls– authentication through use of X.509 certifcates– OMII test bed
• Portals– Support access to the NGS.– Tied in with JISC VRE developments
• Evaluations– InnerGrid - Contractual issues delayed start - just started.– OMII – Start later this month– GT4 – Start later this month– gLite – start next month

Stuff We Don’t Do
• Run a repository• Develop software
– contribute to developments to influence/adapt cf “I’ve got one of those you can have. You just need to …”
• (Training – Edinburgh/NeSC are part of GOSC)• Extensive user hand-holding and app support
– Need the e-Science Centres– Priorities will be driven by users

How do I Join ?
• Acceptable use and Security policies• Install required interfaces (~EGEE)
– VDT– EGEE CE and SE interfaces (and
Authorisation)– Monitoring and accounting
• Provide services as defined in your own SLD– Buys you representation at the board (?)
