CERN/2379/Rev: Proposal for building the LHC computing environment at CERN (Phase 1)
Goals of Phase 1 of the Global LHC Computing Grid project
Technology development and data challenges of the experiments from 2001 onwards leading to a Production Prototype at CERN and in MS and NMS by 2004
Technical Design Report in 2003 describing
the necessary size and cost of the production facility at CERN and elsewhere
agreeing the relations between the distributed Grid nodes
their coordinated deployment and exploitation
This Project provides for high level training and technology opportunities significant well beyond particle physics
Approved in the Council Meeting of 20-Sept-01
Project Leader nominated: Les Robertson/CERN
SC2 chair proposed: Matthias Kasemann/FNAL
Project organisation frame
Progress in identifying partners of LHC Computing Grid
Contributions to Phase 1, not complete, but sufficient to approve project start

CERN openlab concept
Create synergies between basic research and industry
Research provides challenge, industry provides advanced items, concepts into collaborative forum
Participation fee
Create a Collaborative Forum between public sector and industries:
to solve a well defined problem through
open integration of technologies, aiming at open standards
(open standard for example: Web with html, xml )

Status of DataGrid
Started on 1/1/2001, 9.8 M Euros EU funding, 21 partners (Main partners from CERN member states funding agencies, institutions: PPARC, INFN, CNRS, NIKHEF, ESA)
Programme of work concentrated on middleware, test beds and applications (90% HEP/LHC focussed)
Project in good shape ready for first test bed to be released to applications by October. Formal EU deadline at the end of the year. First EU review in March 2002.
Other EU projects: CrossGrid, DataTAG and, later, Dissemination Cluster

9. Collaboration with other Grid activities
Intensive work of collaboration with other Grid projects in Europe (EU Projects, GridPP, INFN-Grid, etc) and elsewhere (mostly in US: GriPhyN, PPDG, DTF, iVDGL), to ensure interoperability of the various grid efforts
Major role in international bodies: GGF (Global Grid Forum) and InterGrid (coordination among HEP Grid projects)
Starting effort to LHC Computing Grid
Monitor and support (within capabilities) similar activities in other sciences

INFN Grid
iVDGL
CrossGrid

10. Member State and other Contributions to Phase 1
Personnel: ~ 40 fte needed for three years and more pledged
Funds: ~30 MCHF needed and >10 MCHF pledged from various sources
More work required to guarantee the envisaged vigorous test phase
17-Dec-19
LHC Computing, RRB; H F Hoffmann

11. Proposed Contributions
Continue discussion with all Member States and other Countries, Agencies, industrial firms
Proposed manpower very welcome, more details in “Staffing requirements for the CERN component of the LHC Computing Grid Project” (preliminary)
Work out convention with each funding agency
Need still more funds for the CERN prototyping;
Overhead per person? Taking the discussion basis of Italy and UK: ~50KCHF/fte*year?
Contributions in kind according to project specification?
EU may give more in FP6
Aim at more industry contributions through “CERN openlab for DataGrid applications”
Critical level for “approval to start the project” reached
Project phase 1 approved as proposed, provided the resources can be identified

Next Steps
POB, PEB, SC2 first meeting in November or December
Identify dates
Write letters to experiments requiring proposals of participants
Write letters to contributors requiring proposals of participants
Names required by mid November, in order that boards can have first meetings already this year
Early next year: Launching Workshop for all those doing the work (later ~one “LHC Computing Grid” week/year?)
