LHC Computing, SPC-FC-CC-C; H F Hoffmann8 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 Hoffmann9 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 Other EU projects: CrossGrid, DataTag and, later, Dissemination Cluster

LHC Computing, SPC-FC-CC-C; H F Hoffmann10 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 Hoffmann11 DataTAG Main partners: CERN, INFN, PPARC, University of Amsterdam Main focus on transatlantic test beds with correspondent US projects (DTF, iVDGL) Important to compensate limited resources on network developments in DataGrid 2 years (2002-3), 4 M Euros (1.2 for US-EU link)

LHC Computing, SPC-FC-CC-C; H F Hoffmann12 CrossGrid Early adoption and further development of DataGrid middleware, deployment of testbeds in other CERN member states (Poland, Germany, Spain, Greece, etc.) 23 partners (PL, D, SK, A, CY, NL, I, UK, IRL, E, EL) 6 M Euros EU funding, Industrial participation: Algosystems SA EL Important to extend Grid technology to other CERN member states not already in DataGrid

LHC Computing, SPC-FC-CC-C; H F Hoffmann13 Member State Contributions to Phase 1

LHC Computing, SPC-FC-CC-C; H F Hoffmann14 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
