2. You’ve heard about LCG… … so what’s happening in the UK? LCG Deployment, now and future The wider UK picture ….and what’s this EGEE? The Plan

3. In LCG Context A. Management Structure ARDA Expmts EGEE LCG Deployment Board Tier1/Tier2, Testbeds, Rollout Service specification & provision User Board Requirements Application Development User feedback Metadata Workload Network Security Info. Mon. PMB CB Storage

4. Recent LCG Tier1 +10 other sites DCs Tier2 structure Support structure GOC Monitoring LCG Accounting

5. GridPP Summary: From Prototype to Production BaBar D0 CDF ATLAS CMS LHCb ALICE 19 UK Institutes RAL Computer Centre CERN Computer Centre SAMGrid BaBarGrid LCG EDG GANGA EGEE UK Prototype Tier-1/A Centre CERN Prototype Tier-0 Centre 4 UK Tier-2 Centres LCG UK Tier-1/A Centre CERN Tier-0 Centre 2007 2004 2001 4 UK Prototype Tier-2 Centres ARDA Separate Experiments, Resources, Multiple Accounts 'One' Production Grid Prototype Grids

6. Vision GridPP2 should deliver a production quality grid Meeting the computing needs of UK Particle Physics Autonomous and self-supporting with its own identity Participating in LCG, EGEE, BaBarGrid, SAMGrid, and any others desired by its members Part of an integrated UK Grid Independent but integrated, separate but seamless

7. Delivery Plans Keep up with LCG Participate in LHC Data Challenges TierA for BaBar and BaBarGrid Participate in LCG Service Challenges Use by other VOs Put in place the structure to deliver this …..and more

8. Production Team Deployment User Support Middleware Support Applications Support Network Support Security Operations

9. UK Tier-2 Centres NorthGrid **** Daresbury, Lancaster, Liverpool, Manchester, Sheffield SouthGrid * Birmingham, Bristol, Cambridge, Oxford, RAL PPD, Warwick ScotGrid * Durham, Edinburgh, Glasgow LondonGrid *** Brunel, Imperial, QMUL, RHUL, UCL Current UK Status: 11 Sites via LCG

10. Tier2 Centres UK model of distributed Tier2 Centres Managerial and organisational ‘centre’ Tier2 is free to organise internally –so I cannot describe yet Tier2 is smaller than an EGEE Region –but some aspects of the model may be useful (their own VO? own RB?) May hide some of the internal structure CE, GIIS?

11. Deployment A Team to roll out software across UK Software release certification, installation support, site certification Specialist support for sysadmins Consists of staff from T1 + T2

12. User Support Migrate from mailing list to problem- tracking From sysadmin support to user support Managed Helpdesk –for assignment, tracking, escalation We already have a lot of experience –we haven’t encapsulated it in FAQs etc

13. Middleware, Security and Network Development M/S/N builds upon UK strengths as part of International development Configuration Management Storage Interfaces Network Monitoring Security Information Services Grid Data Management Security Middleware Networking

14. Middleware Support GridPP2 Middleware development should have an emphasis on delivery and support Middleware teams should support their software area T2 assigned 5 specialist support posts Integrate support effort into Production Team

15. Applications Support Stephen Burke – roaming support 2 T1 experiment-facing people UK experiments Get deployment and middleware support working with experiments –to ensure successful UK involvement in experiments’ use of Grid.

16. Network Support Mark Leese (CCLRC-DL) –Rolled out network monitoring to UK Core e-Science programme –GridPP2 role in network support –Network optimisation –Participation in service challenges –Hopefully using lightpaths

17. Security New Security Officer (to be appointed) –Security operations Consultants –Kelsey - Joint EGEE-LCG Security –Jensen – technical advice to CA/ middleware –McNab – e-Science Security Centre Track UK developments (Permis, Shibboleth)

18. Grid Operations

19. GOC GridSite MySQL Resource Centre Resources & Site Information EDG, LCG-1, LCG-2, … ce se bdii rb Monitoring Secure Database Management via HTTPS / X.509 RC

20. Operations LCG Operations centre EGEE ROC Monitor GridPP (and NGS and GridIreland) Developed tools for LCG, reuse for GridPP Continue developing for EGEE EGEE CIC running grid-wide services Accounting

21. LCG Core Accounting

22. Wider Support GSC –UK helpdesk –UK E-Science CA Training –Our own and EGEE(NeSC)

23. Other UK Grids NGS –National Grid Service –4 large clusters + 2 UK Supercomputers –Already using VDT and BDII ETF –Developing UK OGSA/WSRF Grid UK Grid Operations Centre Director –Speaking next Should all be part of EGEE

24. EGEE UK/I Region in EGEE covers GridPP, NGS, and Grid Ireland – one of 10 regions EGEE’s aim is to integrate national grids –Not to interfere or impose limits on them All of the work I have described, short of actually running the Resource Centres, is EGEE work –Many sites are actually signed up to EGEE so we can report it formally as such –Many of you will be asked to report work to EGEE (timesheets, quarterly reports) but this shouldn’t be an imposition The development of GridPP will be aligned with EGEE –But EGEE is not well defined, so we plan GridPP and participate in the developing EGEE to learn, adopt, and influence.

25. EGEE Issues EGEE=LCG? –non-European sites in LCG –non-LCG sites in EGEE Platform Support –non-Linux, free linux (cf RHEL) Integrated user support Support for new VOs Security, security, security

26. The Next Steps Just appointed Jeremy Coles –as GridPP Production Manager Grid Definition –define GridPP, –get buy-in of stakeholders Production Team –build the team Workplan

27. Production Manager Tasks Develop work plan (deliverables/milestones) Compile problems and issues list (implement tracking) Organise a GridPP deployment group workshop Better establish GridPP identity – address UK specific needs Review/develop operating procedures to maintain GridPP service Get GridPP more involved at UK/experiment software meetings Coordinate UK Tier-2 resource input to LCG and EGEE Work with other grids to establish a single production grid.

28. Running a production service: areas to be reviewed and developed Main areas to be considered (transparency, control, accountability, security, improvement) Grid accounting –Who needs to know what and in what form? Where are the gaps in LCG accounting? Grid monitoring –Service-level management tools. Efficiency of resource usage. Replication issues. –Detailed metrics to be agreed –Real-time notification and problem resolution Management & reporting –Grid management: VO setup procedures; adding new Tier-2 resources –Frequency, structure and content of reports to be agreed (e.g. resource usage, job success rates against targets) Security –Processes and procedures (e.g. incident handling) –Mechanics of trust model defined: identity, privacy, policy and authority. (e.g how are rights revoked. Appeals.) –Misuse of resources (intrusion), user & usage audits Support –Installation (joining) requirements/guidelines –integration & helpdesk requirements –Library – deployment documentation. User feedback – mechanism to inform future developments Training –For new GridPP users and new operations staff Middleware release strategy (and stabilisation!) Tier-2 management –Service levels (SLAs/MoUs to be developed) –Resource, quota and priority handling Resource –Maintenance plans Audit –Of Grid usage by user/VO

29. Vision GridPP2 should deliver a production quality grid Meeting the computing needs of UK Particle Physics Autonomous and self-supporting with its own identity Participating in LCG, EGEE, BaBarGrid, SAMGrid, and any others desired by its members Part of an integrated UK Grid Independent but integrated, separate but seamless

30. Challenge LCG has given us a good base –We now have a critical mass based on LCG2 Make it production quality grid Attract the satellite grids UKQCD, BaBar, –And bring in other experiments Participate fully in LCG and EGEE –Without alienating non LHC experiments

31. Can we do it? Yes, we can!
