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

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 publicsector 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: 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

16-09-2001 LHC Computing, SPC-FC-CC-C; H F Hoffmann 10

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

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
