Beyond GridPP2..
2. Funding from September 2007 will be incorporated as part of PPARC’s request for planning input for LHC exploitation from the LHC experiments and GridPP that will be considered by a Panel consisting of Prof. G. Lafferty (Chair), Prof. S. Watts and Dr. P. Harris meeting over the summer to provide input to Science Committee in the Autumn.
1. An important issue to note is the need to ensure matching funding is fully in place for the full term of EGEE-2, anticipated to be 1st April 2006 to 31st March Such funding for SA1 and JRA1 is currently provided by PPARC through GridPP2, but this will terminate under current arrangements at the end of GridPP2 in August There is thus a 7 month gap for which matching funding is currently not in place. This needs to be resolved, with some urgency, before the proposal is submitted this summer.

3. Enabling Grids for E-science in Europe
Deliver a 24/7 Grid service to European science
build a consistent, robust and secure Grid network that will attract additional computing resources.
continuously improve and maintain the middleware in order to deliver a reliable service to users.
attract new users from industry as well as science and ensure they receive the high standard of training and support they need.
100 million euros/4years, funded by EU
>400 software engineers + service support
70 European partners

5. LHC EXPLOITATION PLANNING REVIEW
Beyond GridPP2..
LHC EXPLOITATION PLANNING REVIEW
Input is requested from the UK project spokespersons, for ATLAS and CMS for each of the financial years 2008/9 to 2011/12, and for LHCb, ALICE and GridPP for 2007/8 to 2011/12.
Physics programme
Please give a brief outline of the planned physics programme. Please also indicate how this planned programme could be enhanced with additional resources. In total this should be no more than 3 sides of A4. The aim is to understand the incremental physics return from increasing resources.
Input will be based upon PPAP roadmap input
E-Science and LCG-2 (26 Oct 2004)
and feedback from CB (12 Jan & 7 July 2005)

6. Grid and e-Science funding requirements
Simple model

Collaboration Board Meeting

7. Priorities: GridPP2 Proposal
Tier-1/A staff – National Grid Centre
Tier-1/A hardware – International Role
Tier-2 staff – UK e-Science Grid
Applications
Grid Integration (GridPP2)
Development (experiments proposals)
Middleware – EU-wide development
Tier-2 hardware – non-PPARC funding
CERN staff – quality assurance
CERN hardware – pro-rata contribution
Established entering proposal writing phase…
ALL of
these
are
required to
address
the LHC

9. UK Analysis for the LHC Experiments I
The basic functionality of the Tier-1 is:
ALICE - Reconstruction, Chaotic Analysis
ATLAS - Reconstruction, Scheduled Analysis/strimming, Calibration
CMS - Reconstruction
LHCb - Reconstruction, scheduled strimming, chaotic analysis
The basic functionality of the Tier-2s is:
ALICE - MC Production, Chaotic Analysis
ATLAS - Simulation, Analysis, Calibration
CMS - Analysis for Physicists, All Simulation Production
LHCb - MC Production, No analysis

Management?
Current Proposed Model is low cost
SCAP PPARC committee provide overview – (comment: PPARC could e.g. appoint a project leader)
Production manager (PPARC) + 4 Tier-2 coordinators (EU) + Operations Centre
(comment: EU funding likely in 2008 on.. But will it fund these people?)
No PMB, CB – devolution to institutes
Some concerns that this will not work

FEC?
Computers funded via SRIF3 (+eSRIF4?) – OK up to 2010 [see Steve’s slides]
However, in future - CHARGE:
Power usage
support staff time
maintenance (routine/emergency)
space charges
share of the replacement capital item cost
(if so, effect comes earlier than end of SRIF)

13. Collaboration Board Meeting
FEC? Back of envelope
Estimated costs per annum
Power usage (200 CPUs +disk) ~50k
support staff time ~50k
maintenance (routine/emergency) ~?
space charges ~?
replacement capital item cost ~50k
FEC ~150k
[None of this “scales” but…]
5,000 CPUs ~ £4m p.a.
Current proposed model =
£2m via SRIF + £1.3m PPARC + £0.7m Institutes
Hardware Manpower Power, Space
FEC model = ??
Comment: Dual Funding was excellent value for HEP
Comment: Tier-2 functionality is needed (wherever it resides)
