8 GridPPe-Science PresentationSlide 8 Experiment Objectives Vertically integrated programme? Broken component model… Specific experiments or overall reduction? To be determined by Experiments Board 50% reduction? 23 SY

9 GridPPe-Science PresentationSlide 9 CERN (Component 3) Basic Grid functionality: UK-CERN integrated programme - synergies, but cuts here will impact… 10% reduction? 3.1 SY

10 GridPPe-Science PresentationSlide 10 CERN (Component 4) Experiments support: similar conclusions to UK- based programme Non-UK funding dependencies? 50% reduction? 11 SY Pro-rata reduction on disk, tape, CPU... +HARDWARE 15% reduction? £0.2M

11 GridPPe-Science PresentationSlide 11 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

12 GridPPe-Science PresentationSlide 12 £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%

13 GridPPe-Science PresentationSlide 13 £15M Project Summary Even a £21-20M reduction is not trivial.. EU DataGrid commitments are built in Focus on CERN and UK Capital as largest single items, then reduce workgroup allocations £17M budget cuts hard into the project –Examples are based on original Component Model £15M budget is impossible within the Component Model A fixed allocation help in planning the start-up phase

14 GridPPe-Science PresentationSlide 14 International Comparisons PP Grids under development France Germany Italy US –CMS –Atlas Tier1 starting up at Karlsruhe BaBar TierB at Karlsruhe Tier2 for ALICE at Darmstadt No national Grid - project led Tier-1 RC for all 4 LHC experiments at CC-IN2P3 in Lyon BaBar TierA an LHC prototype starting now National Core Grid (2M/year) 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 Tier1 at Brookhaven INFN National Grid based round EU- DataGrid Tier-1 RC and a prototype starting now in CNAF, Bologna 15.9M is allocated during for Tier-1 hardware alone Tier1 staff rising to 25 FTE by Tier2 centres at 1M/year

15 GridPPe-Science PresentationSlide 15 International Comparisons Summary - different countries, different models France & Germany budget for hardware, assume staff Italy - lots of hardware and staff US - funds split between Tier1/2, Universities, infrastructure, and R&D Italy > UK ~ France (EU) ~US (GriPhyN, PPDG and iVDGL characteristics within GridPP: single UK programme) ~

16 GridPPe-Science PresentationSlide 16 GridPP Architecture Based on EU DataGrid developments feeding into GGF Status: Version 2 (2/7/01) Key elements: –Evolutionary capability –Service via Protocols and Client APIs –Representation using UML (TogetherSoft) –Defines responsibilities of Work Packages –Built from Infrastructure –Based on PP Use Cases (applies to GridPP) 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

17 GridPPe-Science PresentationSlide 17 The Grid and Industry Help us develop the Grid: –Supply hardware - PCs, Disks, Mass Storage, Networking etc –Supply software, middleware, management systems, databases etc Use the Grid for themselves: –Collaborative Engineering –Massive simulation –Federating their own worldwide databases Sell or develop the Grid for others: –Computation Services, Data services etc

18 GridPPe-Science PresentationSlide 18 Summary Balanced exploitation programme costs £21M £20M-£17M-£15M 3-year funding scenarios examined £20M = maintains balanced programme £17M = reduced experimental objectives £15M = eliminates experimental objectives Final balance depends on funding allocation Emphasis on vertical integration: component model International comparisons: Italy > UK ~ France (EU) ~US (GriPhyN, PPDG and iVDGL characteristics within GridPP: single UK programme) Contacts established with GriPhyN, PPDG and iVDGL InterGrid Co-ordination Group in development Architecture defined by GGF via lead in DataGrid Industry links: emphasis on partnership ~

19 GridPPe-Science PresentationSlide 19 GridPP and VISTA Astrogrid will federate VISTA data with other large databases elsewhere –this 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 –very 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 (GenGrid) as to how we can collaborate and share expertise and middleware

20 GridPPe-Science PresentationSlide 20 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 retrieved Current status and archived load information is plotted... To be done... –JAVA CoG kit being investigated (more robust) –Simple monitoring system to verify test-bed timestamps (in case not everyone is using NTP) –Integrate with the Grid Monitoring Architecture –Incorporate current network bandwidth measurements into graphical system –Automatic notification system
