RAW data processing #38130: VPass for LHC12h – 226 runs, done Re-CPass0/CPass1 of LHC12i - done

RAW data reconstruction strategy for LHC13a p-A

Reconstruction passes (1) Immediate reconstruction of Calorimeter and Muon data Similar to LHC12h, LHC12i Using trigger alias kPhysME No prior calibration necessary Fast reconstruction – mid-sized run is ready for analysis ~5 hours after data taking Independent on data taking/trigger cluster Small output ~2% of RAW, including ESDs, AODs and QA

Reconstruction passes (2) Standard CPass0/CPass1 Using trigger aliases kCalibOuter/kCalibBarrel Ready ~24 hours after data taking Output – calibration objects and QA There are sufficient CPUs to run both (1) and (2) in parallel

Reconstruction passes (3) VPass (adhering to current calibration schema) At the end of period One week after the end of last run – following period of manual calibration and changes of code (if needed) On 10% of RAW Output – ESDs, AODs and QA

Reconstruction passes (4) Full pass (adhering to current calibration schema) At the end of period One week after the end VPass – following QA only If any of the calibration or code requires changes, then another VPass Output – ESDs, AODs and QA

Reconstruction passes (5) p-A period – two reconstructions Same job (more efficient) Two separate jobs (less chances of interference) Reconstruction of ‘FAST’ cluster, no SDD Based on trigger alias Reconstruction of ‘ALL’ cluster Two separate ESDs/AOD and QA(?)

Reconstruction passes (6) Possible extensions/changes Manual TPC calibration to fix integrated-luminosity dependent distortion of space points within part of the acceptance: ~-0.3<eta<0. Fast reconstruction after CPass0/CPass1 – shortening of the QA and manual upgrades strategy (if possible)

Preparation  Bug fixes (if done) related to QA/Calibration can be checked in full pass of LHC12h Highly desirable MC (Label=0) memory fragmentation fix can be checked with Pb-Pb MC, next cycle is LHC12a17a_fix (central 0-10%) Reconstruction strategy and trigger aliases should be clarified and prepared asap Additional input from PWG-PP needed
