1 GridPP Presentation to PPARC Grid Steering Committee 26 July 2001 Steve Lloyd Tony Doyle John Gordon

2 GridPPe-Science PresentationSlide 2 Outline Resource Allocation and Funding Scenarios Int l Financial Comparisons Int l Grid Collaborations - see addendum Grid Architecture Links with Industry - see addendum 1. VISTA and GridPP 2. GridPP monitoring page Summary

3 GridPPe-Science PresentationSlide 3 GridPP Proposal GridPP = Vertically integrated programme = Component Model... Provides input for £15-20M funding scenarios...

4 GridPPe-Science PresentationSlide 4 GridPP Workgroups A - Workload Management Provision of software that schedule application processing requests amongst resources B - Information Services and Data Management Provision of software tools to provide flexible transparent and reliable access to the data C - Monitoring Services All aspects of monitoring Grid services D - Fabric Management and Mass Storage Integration of heterogeneous resources into common Grid framework E - Security Security mechanisms from Certification Authorities to low level components F - Networking Network fabric provision through to integration of network services into middleware G - Prototype Grid Implementation of a UK Grid prototype tying together new and existing facilities H - Software Support Provide services to enable the development, testing and deployment of middleware and applications at institutes I - Experimental Objectives Responsible for ensuring development of GridPP is driven by needs of UK PP experiments J - Dissemination Ensure good dissemination of developments arising from GridPP into other communities and vice versa Technical work broken down into several workgroups - broad overlap with EU DataGrid

5 GridPPe-Science PresentationSlide 5 Components 1-4: £21M I: 11.9% Experiment Objectives H*: 5.4% H: 3.2% Software Support G: Prototype Grid 9.7% F* 1.5% F 1.9% CERN Staff 27.0% CERN Hardware 6.8% J 2.6% E 1.7% D* 1.5% D 2.7% C* 0.6% C 1.1% B* 1.9% B 1.5% A* 0.4% A 1.4% UK Managers 1.9% UK Capital 15.3% Work Groups A - F

6 GridPPe-Science PresentationSlide 6 Starting Points PPARC EU DataGrid commitments are built in (£2.4M, noted in Table 3) - cannot be reduced CERN component (1/3) scales with total UK Capital (£3.2M, largest single item) assessed then address workgroup allocations...

7 GridPPe-Science PresentationSlide 7 £20M Project I: 11.9% Experiment Objectives H*: 5.4% H: 3.2% Software Support G: Prototype Grid 9.7% F* 1.5% F 1.9% CERN J 2.6% E 1.7% D* 1.5% D 2.7% C* 0.6% C 1.1% B* 1.9% B 1.5% A* 0.4% A 1.4% UK Managers 1.9% UK Capital Work Groups A - F £7.1m £6.7m £3.2 £ %

8 GridPPe-Science PresentationSlide 8 £17M Project I: £2.49m £1.2m Experiment Objectives H*: 5.4% H: 3.2% Software Support G: Prototype Grid 9.7% F* 1.5% F 1.9% CERN J 2.6% E 1.7% D* 1.5% D 2.7% C* 0.6% C 1.1% B* 1.9% B 1.5% A* 0.4% A 1.4% UK Managers 1.9% UK Capital Work Groups A - F £7.1m £6.7m £6.0m £3.2 £2.9 £2.45m 90.0%

9 GridPPe-Science PresentationSlide 9 Experiment Objectives Vertically integrated programme? Broken component model… Specific experiments or overall reduction? To be determined by Experiments Board 50% reduction? 23 SY

10 GridPPe-Science PresentationSlide 10 Workload/Data Management Reduced long-term programme? e.g. scheduler optimisation (WG A) query optimisation (WG B) … or overall reduction? 10% reduction? 1.2 SY

11 GridPPe-Science PresentationSlide 11 £15M Project I: £2.49m £0 Experiment Objectives H*: 5.4% H: 3.2% Software Support G: Prototype Grid 9.7% F* 1.5% F 1.9% CERN J 2.6% E 1.7% D* 1.5% D 2.7% C* 0.6% C 1.1% B* 1.9% B 1.5% A* 0.4% A 1.4% UK Managers 1.9% UK Capital Work Groups A - F £5m £3.2 £2.9 £2.45m 90.0%

12 GridPPe-Science PresentationSlide 12 Conclusions Even a £21M to £20M reduction is not trivial.. £17M budget cuts hard into the project: especially User layer of Grid architecture: Experimental Objectives (50% reduction) Effect of 10% reduction on other groups e.g. WG A/B –Evaluation based on Component Model: Components 1-4 correspond to Grid exploitation £15M budget is impossible within the Component Model

13 GridPPe-Science PresentationSlide 13 International Comparisons PP Grids under development France Germany Italy US –CMS –ATLAS Tier-1 at FNAL and 5 Tier-2 centres Prototype built during , with full deployment during Staff estimates for the Tier-1 centre are 14 FTE by 2003, reaching 35 FTE in Integrated costs to 2006 are $54.7M excluding, GriPhyN and PPDG ATLAS plans very similar to CMS with costs foreseen to be the same Tier-1 at Brookhaven Tier-1 RC for all 4 LHC experiments at CC-IN2P3 in Lyon BaBar Tier-A an LHC prototype starting now National Core Grid (2M/year) Tier-1 starting up at Karlsruhe BaBar Tier-B at Karlsruhe Tier-2 for ALICE at Darmstadt No National Grid - project led INFN National Grid based on EU DataGrid Tier-1 RC and a prototype starting now in CNAF, Bologna 15.9M is allocated during for Tier-1 hardware alone Tier-1 staff rising to 25 FTE by Tier-2 centres at 1M/year

14 GridPPe-Science PresentationSlide 14 International Comparisons Summary - different countries, different models France & Germany budget for hardware, assume staff Italy - significant investment in hardware and staff US - funds split between Tier1/2, Universities, infrastructure, and R&D Italy > UK ~ France ~ Germany ~US (GriPhyN, PPDG and iVDGL characteristics within GridPP: single UK programme) ~

15 GridPPe-Science PresentationSlide 15 GridPP Architecture GGF architecture via EU DataGrid incorporating PPDG and GriPhyN developments EU DataGrid Architecture Status: Version 2 (2/7/01) Key elements: –Evolutionary capability –Services via Protocols and Client APIs –Representation using UML (TogetherSoft) –Defines responsibilities of Work Packages –Based on PP Use Cases - direct application to GridPP GridPP (and PPDG) project management using Xproject = implementation to defined timescales The DataGrid Architecture Version 2 German Cancio, CERNSteve M. Fisher, RALTim Folkes, RAL Francesco Giacomini, INFNWolfgang Hoschek, CERNDave Kelsey, RAL Brian L. Tierney, LBL/CERN July 2, 2001

16 GridPPe-Science PresentationSlide 16 GridPP and VISTA Astrogrid will federate VISTA data with other large databases –requires that VISTA data has already been processed and catalogues and images are available VISTA have a proposal (e-VPAS) that concentrates on producing the databases on which the Astrogrid tools will work. This work has much in common with GridPP: –a similar timescale –large data flows from one remote site –many distributed users –reprocessing of data –utilization of distributed computing resources GridPP have started discussions with VISTA and EPCC in order to collaborate and share expertise and middleware

17 GridPPe-Science PresentationSlide 17 GridPP Monitoring Page Various sites now set up with UK Globus certificates –Grid Monitoring Polls Grid test-bed sites via globus-job-run command Runs basic script producing XML encoded status information Load average and timestamp information is retrieved Current status and archived load information is plotted...

18 GridPPe-Science PresentationSlide 18 Summary Balanced exploitation programme costs £21M £20M-£17M-£15M 3-year funding scenarios examined £20M = maintains balanced programme £17M = significantly reduced experimental objectives £15M = eliminates experimental objectives Programme optimisation depends on funding allocation International comparisons: Italy > UK ~ France ~ Germany ~US (GriPhyN, PPDG and iVDGL characteristics within GridPP: single UK programme) Individual contributions to GGF architecture via leading role in EU DataGrid combined with strong links to GriPhyN, PPDG and iVDGL Industry links: emphasis on partnership Exploring common development programme with VISTA Demonstrators in development ~
