1. Slide § David Britton, University of Glasgow IET, Oct 09 1 Prof. David Britton GridPP Project leader University of Glasgow GridPP delivering The UK Grid for Particle Physics Joint NDGF/GridPP Meeting 21 st October 2013

2. Slide GridPP Tier-1 at Rutherford Lab. Four distributed Tier-2s at 19 sites: ScotGrid: Durham, Edinburgh, Glasgow NorthGrid: Lancaster, Liverpool, Manchester, Sheffield SouthGrid: Birmingham, Bristol, Cambridge, JET, Oxford, RAL-PPD, Sussex London: Brunel, Imperial, QMUL, RHUL, UCL 44,000 logical CPUs (10,000 at RAL) 23 PB of disk (11PB at RAL) 11PB of tape (at RAL).

4. Slide GridPP History GridPP1 (2001-04); GridPP2 (2004-07); GridPP2+ (2007-08) GridPP3 (2008-2011); GridPP4 (2011-2015); Total funding ~£90m (£6m-£7m/year). Currently 55 FTE. GridPP kick started wLCG with £5.6m in 2001-04 David Britton, University of Glasgow 4 UK funded LCG posts at CERN GridPP and UK also contributed to DataGrid EDG EGEE x 3

5. Slide Next… GridPP5 proposal (2015  3/4/5 years?) needs to be submitted by March 2014. Currently on hold pending outcomes from CSR and PR, which will determine the scale. Or will there be a GridPP4+ ? UK reviewing EGI subscription. David Britton, University of Glasgow 5

6. Slide View from 2009 GridPP has complemented the development of the UK National Grid Service, by developing a larger-scale, but more specialised Grid. In so doing GridPP is a foundation stone for the future UK NGI, which will relate to the EU structures.

8. Slide GridPP Delivery David Britton, University of Glasgow RCUK e-Science Review 8 Largest non-US contributor of resources to the LHC experiments (10-year view or 1 year view) 9.8% of CPU delivered to non-LHC VOs over 10-years; 7.3% in the last year.

10. Slide GridPP Mission LHC: To provide the UK fraction of the computing requirements of the LHC experiments… (ALICE 2% of global requirements; ATLAS 12%, CMS 8%, LHCb 30%) Others: To enable other (academic/STFC/physics?) collaborations to make use of the computing infrastructure and to provide resources at the 5%-10% level. (T2K, NA62, PhenoGrid…) Other Others: More recently, increase emphasis on ‘Impact’ and engagement with UK-PLC, SME’s in particular. Other-others also could include other academic disciplines where ‘impact’ can be more immediate (eg. biomedical – impact on quality-of-life or health-and- wellbeing).

14. Slide Threats and Opportunities Future funding: We need to do more with less and maintain/increase delivery to the LHC experiments. –Technical advances –Structural evolution UK ecosystem: We need to establish our place (showing relevance without being distracted, or replaced!) –Our international environment is a potential strength –Our experience with large volumes of data is an asset At some level, delivery to the LHC has become a necessary, but not a sufficient, condition for success.
