GridPP VisionGridPP Vision

From Web to Grid - Building the next IT Revolution

PremiseThe next IT revolution will be the Grid. The Grid is a practical solution to the data-intensive problems that must be overcome if the computing needs of many scientific communities and industry are to be fulfilled over the next decade.

Aim

The GridPP Collaboration aims to develop and deploy a large-scale science Grid in the UK for use by the worldwide particle physics community.

GridPP ContextGridPP Context 5. Interoperability5. Interoperability


Grid issues – CoordinationGrid issues – Coordination

• Technical part is not the only problem • Sociological problems? resource sharing

– Short-term productivity loss but long-term gain

• Key? communication/coordination between people/centres/countries– This kind of world-wide close coordination across multi-national

collaborations has never been done in the past

• We need mechanisms here to make sure that all centres are part of a global planning

– In spite of different conditions of funding, internal planning, timescales etc

• The Grid organisation mechanisms should be complementary and not parallel or conflicting to existing experiment organisation

– LCG-DataGRID-eSC-GridPP– BaBar-CDF-D0-ALICE-ATLAS-CMS-LHCb-UKQCD

• Local Perspective: build upon existing strong PP links in the UK to build a single Grid for all experiments


Authentication/AuthorizationAuthentication/Authorization

GridPP –GridPP – Achievements and Issues Achievements and Issues

• 1st Year Achievements• Complete Project Map

– Applications: Middleware: Hardware

• Fully integrated with EU DataGrid and LCG Projects

• Rapid middleware deployment /testing

• Integrated US-EU applications development e.g. BaBar+EDG

• Roll-out document for all sites in the UK (Core Sites, Friendly Testers, User Only).

• Testbed up and running at 15 sites in the UK

• Tier-1 Deployment• 200 GridPP Certificates issued• First significant use of Grid by an

external user (LISA simulations) in May 2002

• Web page development (GridSite)

• Issues for Year 2• Status: 30 Aug 2002 17:38 GMT

– monitor and improve testbed deployment efficiency from Sep 1…

• Importance of EU-wide development of middleware

• Integrated Testbed for use/testing by all applications

• Common “integration” layer between middleware and application software

• Integrated US-EU applications development

• Tier-1 Grid Production Mode• Tier-2 Definitions and Deployment• Integrated Tier-1 + Tier-2 Testbed• Transfer to UK e-Science CA• Integration with other UK projects

e.g. AstroGrid, MyGrid…


SummarySummary

• Grid success is fundamental for PP

1. CERN = LCG, Grid as a Service.

2. DataGrid = Middleware built upon Globus and Condor-G. Testbed 1 deployed.

3. Applications – complex, need to interface to middleware.

LHC Analyses – ongoing feedback/development.

Other Analyses have immediate requirements. Integrated using Globus, Condor, EDG tools

4. Infrastructure = Tiered computing to the physicist desktop:

Scale in UK? 1 PByte and 2,000 distributed CPUs

GridPP in Sept 2004 5. Integration = ongoing…6. Dissemination• Co-operation required with other

disciplines/industry7. Finances – under control• Year 1 was a good starting point.

First Grid jobs have been submitted..

• Looking forward to Year 2. Web services ahead..
