  • ATLAS Software & Computing

    Status and PlansDario BarberisUniversity of Genoa (Italy)DOE/NSF Review January 2003, LBNL

  • ForewordI have been designated by the ATLAS Management to be the next Computing Coordinator, and the ATLAS Collaboration Board has been asked to endorse this proposal (e-mail vote by Collaboration Board in process)Main parts of this talk were prepared with contributions of the outgoing Computing Coordinator, N. McCubbin, and several other members of the Computing Steering GroupOrganizational changes outlined at the end of this talk are still proposals being discussed within the ATLAS Collaboration

  • OutlineData ChallengesGRIDGeant4LCGComputing OrganizationSoftware development plans

  • DC0: readiness & continuity tests(December 2001 June 2002)3 lines for full simulation1) Full chain with new geometry (as of January 2002)Generator->(Objy)->Geant3->(Zebra->Objy)->Athena recon.->(Objy)->Analysis 2) Reconstruction of Physics TDR data within Athena(Zebra->Objy)->Athena rec.-> (Objy) -> Simple analysis3) Geant4 robustness test Generator-> (Objy)->Geant4->(Objy)

    1 line for fast simulationGenerator-> (Objy) -> Atlfast -> (Objy)

    Continuity test: Everything from the same release for the full chain (3.0.2)we learnt a lot we underestimated the implications of that statementcompleted in June 2002

  • ATLAS Computing: DC1The Phase1 (G3) simulation (Jul-Aug 2002) was a highly successful world-wide exercise from which we learned a lot, e.g. software distribution, importance of validation, etc. Grid tools were used in Scandinavia (NorduGrid) for their full share of DC1, and in USA for a significant fraction of theirs. Grid tools have also been used for an extensive ATLAS-EDG test involving 6 sites, aimed at repeating ~1% of European DC1 share.We have launched end Nov 2002 Phase 2, i.e. the pile-up (2x1033 and 1034) exercise, following site validation (55 sites) and physics validation. The HLT community specifies details of what samples are to be piled up. Most sites completed by mid-December, last few jobs running right now. About the same CPU neeed as for phase 1 70 Tbyte, 100 000 filesAdditional countries/institutes joined inLarge scale GRID test in since end November in preparation for reconstructionReconstruction February-March 2003using ATHENA.
