  • Sandro: General news
    • next week -> Offline Week
    • pythia8 can be generated on the fly
      • configuration?
      • other generators?
      • set of detectors to simulate, be able to switch on/off detectors for material/active independently
    • MT mode ready
    • material/medium manager
      • difficult to create media in code not deriving from o2::Base::Detector
      • moved into singleton 02::Base::MaterialManager
    • track references request
      • snapshot of a track, mainly for debugging
      • management done by MC stack
      • digitisation, clusterisation reco
        • so fare done by FairTasks
        • but FLP/EPN will use FairMQ devices
        • O2 data-proc layer makes easy to setup FairQM-based processing
          • avoid use FairRunAna
          • towards o2 data-processing workflow
          • simulation can benefit from FairQM
    • event splitting for big events
      • collaborative simulation, subevents in parallel
      • big reduction of memory/process, speedup improvement
      • what about memory consumption of the merger?

 

  • Ruben: WP13 updates
    • ITS-TPC matching
      • ready
      • some details on algorithm
      • performance, <chi2> should be ~4, it is ~10
        • long tails, non optional TPC errors, loopers
      • purity of matching
        • probability of mismatch, according to labels
          • lot of fakes below 1 GeV, improves with chi2 cut < 30
          • extra improvement if fakes excluded 
    • ITS
      • two alternative trackers
      • clusterisation
    • TPC
      • quite advanced, good benchmarks
      • distortion calibration cannot progress w/o TRD
    • TRD
      • porting to O2 makes sense only when sim is working
    • other detectors
      • nothing
    • layout of reco/calib components
      • drifting away from FairRunAna
      • naming of I/O data

 

  • AoB
    • none

      Overview of recent developments for RUN3 simulation
