Comparison of UK L2 grid and PP Grid now(ish) Application PP Applications L2 Grid Value added components EDG 2.0 Value added Components Simple User management ??? UK MDS EDG Info VOMS RB Data Man. Only Linux 7.3 in places GT2 GT2 eScience CA Network monitoring Stakeholders Meeting
Concrete sugestions • Simple back end convergence in places • Make common use of e-Science support centre a reality • Embark on limited do-able steps: step 1 Study and implement Information service convergence “How can Grid-A discover resources on Grid-B, which it can use” • Build on Edinburgh workshop • Natural synergy at CCLRC • Small study group could work this out • May converge on use of R-GMA Stakeholders Meeting

Concrete proposals • Simple back end convergence in places • Make common use of e-Science support centre a reality • Embark on limited do-able steps: step 1 Study and implement Information service convergence “How can Grid-A discover resources on Grid-B, which it can use” • Build on Edinburgh workshop • Natural synergy at CCLRC • Small study group could work this out • May converge on use of R-GMA Stakeholders Meeting
Concrete proposals (2) • ??? step 2 ??? • Mutual acceptance of users credentials and roles (Im way out of my depth here… but…) • User credential issuing should be left to VOs – and should be arbitrary • ? Resource VO agreements should be standardised • ? Scalable way of checking any credential against policy is needed • Lots of UK expertise !! … and in all this keep GGF developments in mind Stakeholders Meeting
Needs: • Policy agreement • Mandate and resource for small working parties to study and recommend convergence solutions • Resource to do something about it Stakeholders Meeting
Application PP Application L2 Grid PP Grid GT2 GT2 Possibility for future ~ 1 year timescale If UK is backing EGEE (which it is).. ..then it probably makes sense to embrace EGEE-0 which will be based upon GT2 … this way we would influence development, and reap benefit of leverage EGEE-0 (GT2) Stakeholders Meeting
… and for the future GT3 • EGEE will probably want to pilot GT3 as “production service” by end 2004 (PP wont move seriously to GT3 production Grid until then) • EGEE should procure from outside • EGEE needs GT3 value added services developing and proving !! UK e-Science L3 Grid could be TRAILBLAZING Stakeholders Meeting
