Beyond GridPP2..
2. Funding from September 2007 will be
incorporated as part of PPARCs 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 2008. 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 2007. 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.

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
• gt400 software engineers service support
• 70 European partners

Overview

• EGEE is the Grid Infrastructure Project in Europe
• Take the lead in developing roadmaps, white
  papers, collaborations
• Organise European flagship events
• Collaborate with other projects (including CPS)
• start date April 1
• UK partners
• CCLRCNeSCPPARC (TCD) (n.b. UK e-Science, not
  only HEP)
• NeSC Training, Dissemination Applications
• NeSC Networking
• CLRC Grid Operations, Support Management
• CLRC Middleware Engineering (R-GMA)
• UK 3rd parties
• Glasgow, ICSTM, Leeds, Manchester, Oxford
• Funded effort dedicated to deploying regional
  grids
• UK T2 coordinators

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)

Grid and e-Sciencefunding requirements

• Simple model

PrioritiesGridPP2 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 Computing Challenge

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 20-100 Physicists, All
  Simulation Production
• LHCb - MC Production, No analysis

10
UK Analysis for the LHC Experiments II

• UK Tier-1 (7 of Global Tier-1)
• UK Tier-2 (pre-SRIF3)

11
Grid and e-Sciencefunding requirements

• Priorities in context of a financial snapshot in
  2008
• Grid (5.6m p.a.) and e-Science (2.7m p.a.)
• Assumes no GridPP project management
• Savings?
• EGEE Phase 2 (2006-08) may contribute
• UK e-Science context is
• NGS (National Grid Service)
• OMII (Open Middleware Infrastructure Institute)
• DCC (Digital Curation Centre)

To be compared with Road Map Not a Bid-
Preliminary Input
12
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

13
FEC?

• Computers funded via SRIF3 (eSRIF4?) OK up to
  2010 see Steves 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)

14
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)
