CERN/2379/Rev: Proposal for building the LHC computing environment at CERN (Phase 1)

1. 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 in 2004 • Technical Design Report describing • the necessary size and cost of the production facility at CERN and elsewhere • agreeing the relations between the distributed Grid nodes • their co-ordinated deployment and exploitation • High level training opportunities Meeting of the Council Delegates and 3 meetings of the Launching Committee • 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 LHC Computing, SPC-FC-CC-C; H F Hoffmann

7. CERN openlab concept • Create synergies between basic research and industry • Research provides challenge, industry provides advanced items, concepts into collaborative forum • Participation fee 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 ) Confidential Public Announcement: Monday, September 24 LHC Computing, SPC-FC-CC-C; H F Hoffmann

8. Status of DataGrid • Started on 1/1/2001, 9.8 M Euros EU funding, 21 partners (Main partners from CERN member states funding agencies: PPARC, INFN, CNRS, NIKHEF, ESA) • Programme of work concentrated on middleware, testbed and applications (90% HEP/LHC focussed) • Project in good shape ready for first testbed 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 LHC Computing, SPC-FC-CC-C; H F Hoffmann

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) • Major role in international bodies: GGF (Global Grid Forum) and InterGrid (coordination among HEP Grid projects) • Starting effort to LHC Computing Grid LHC Computing, SPC-FC-CC-C; H F Hoffmann

10. Member State Contributions to Phase 1 LHC Computing, SPC-FC-CC-C; H F Hoffmann

11. Proposed Contributions • Continue discussion with all Member States • Manpower very welcome, more details in handout “Staffing requirements for the CERN component of the LHC Computing Grid Project” (preliminary) • Work out convention with each funding agency • Need some cash per person at CERN (INFN proposes for their persons 50 KCHF/year) • EU may give more in FP6 • Aim at more industry contributions through “CERN openlab for DataGrid applications” • Cash contributions remain to be completed • Critical level for “approval to start the project” reached LHC Computing, SPC-FC-CC-C; H F Hoffmann
