The Vision ThingThis UK Grid Operation Support Centre is a distributed “virtual centre” providing deployment and operations support for the UK e-Science programme. The centre is a collaboration of CCLRC, the University of Manchester, the University of Oxford, the University of Edinburgh and the White Rose Grid at the University of Leeds. The core of the GOSC is built around operation of the National Grid Service (NGS). The GOSC will support UK services for user authentication, user authorization and project organization, credential management, resource discovery, access portals to facilitate collaborative research and resource sharing across the UK and internationally.

The principal roles of the GOSC (as defined in the original call) include:

– Middleware deployment– Central grid service support– General User support and helpdesk– Network services– Grid Security – User and Administrator support– Interoperability and collaboration with international projects, e.g.

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.

Operations

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

OMII

LCG

•Used for batch production Now.

• worldwide de facto standards

•Currently trying to interface analysis S/W

• on top of gLite from EGEE

•Need to move out of the physics dept’s

GRIDPP • UK Contribution to LCG

– Also supports current users• GridPP1 (2001-2004)

– 33% deployment/operations– 33% middleware dev.– 33% applications

• GridPP2 (2004-2007)– 60% deployment/operations

• LCG2 -> EGEE– 15% middleware dev.– 25% applications

• Not just PPARC funding– Universities

• support LHC• benefit from grid experience• You should know/meet these

people

• Start from LCG2• “Harden” middleware

• Expand applications• €32 from EU

– The EU Grid Infrastructure– 50% deployment/operations– lots at CERN

• matched by PP

• UK + I– training– GOC dev + ops– regional deployment+support

• T2 coordinators

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 (?)

Core services to facilitate collaborative (grid) computing – run by GOSC

Where Next?

• Make the NGS work– Resource Broker/scheduler– VO/Project support– Monitoring and Accounting

• Compatibility with EGEE• Define and agree criteria for success• Web Services

• National e-Infrastructure– Science and Innovation strategy 2004-2014

The Last Slide

• We are in the game of providing a service– built on leading edge academic stuff !

• The challenge– not the latest and greatest grid– not what any given user wants

• The solution– want to make it work

• for our researchers• for our institutions

– one site will not make a useful grid• Sign people/users up (to the vision)

– “get out more”
