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

5. RAW data reconstruction strategy for LHC13a p-A

6. 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

7. 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

8. 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

9. 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

10. 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(?)

12. 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)

14. 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
