LHC Computing, RRB; H F Hoffmann 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 ) 17-Dec-19 LHC Computing, RRB; H F Hoffmann

LHC Computing, RRB; H F Hoffmann 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 17-Dec-19 LHC Computing, RRB; H F Hoffmann

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 DataTAG INFN Grid iVDGL CrossGrid . . . . 17-Dec-19 LHC Computing, RRB; H F Hoffmann

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

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 17-Dec-19 LHC Computing, RRB; H F Hoffmann

LHC Computing, RRB; H F Hoffmann 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?) 17-Dec-19 LHC Computing, RRB; H F Hoffmann
