CERN – Alice Offline – Thu, 20 Mar 2008 – Marco MEONI - 1 Status of Cosmic Reconstruction Offline weekly meeting

CERN – Alice Offline – Thu, 20 Mar 2008 – Marco MEONI - 2 Current Situation Production started on March 17th at 7pm (on global partition LHC08a) Phase 1 – Most Wanted List: 120/857 runs, / raw files – Local steering (see later) – Completion expected by next Tuesday Phase 2 – Low Priority List – Will be steered by LPM – Lightweight Production Manager (see later) – Completion expected during the ALICE week Phase 3 – Missing Dec07's global runs (~10k raw files)

CERN – Alice Offline – Thu, 20 Mar 2008 – Marco MEONI - 3 Phase1: Ongoing Production ~ done jobs Manual intervention is evident No specific Grid problems, only Cluster Monitor stuck on voalice03/06

CERN – Alice Offline – Thu, 20 Mar 2008 – Marco MEONI - 4 Phase1: Failures Others errors: – Input Box: none – Expired: none – Saving: negligible AliRootGrid

CERN – Alice Offline – Thu, 20 Mar 2008 – Marco MEONI - 5 Phase1: few details One job for single chunk (it will be per run in Phase2) Output is about 40MB rec.C added to rec.log (experts review) Packages: AliRoot v4-11-Rev-03, ROOT v b Sites: CERN::LCG, CERN::CERN-gLite Reconstruction time per raw file: 5 minutes in avg (no QA)

CERN – Alice Offline – Thu, 20 Mar 2008 – Marco MEONI - 6 Monalisa DAQ page shows now percentage and number of chunks reconstructed per each run (Costin) Phase1: can be monitored!

CERN – Alice Offline – Thu, 20 Mar 2008 – Marco MEONI - 7 Need to switch to one master-job per run – Now hard to monitor – Now no automatic re-submission to keep the task queue filled – LPM will be used for this purpose JDL already in place – Split by #alienfirstfilename# – waiting for correct functioning of the #aliensplit_se# directive (used to create the output folder for the reconstructed chunks) According to the current reconstruction time per raw file, we expect an "online production"! Phase2

CERN – Alice Offline – Thu, 20 Mar 2008 – Marco MEONI - 8 Conclusions Everything is working, just be patient for results to be computed
