Software & Computing Issues

  • Software
    • Tracker:
      • NaN bug: bug identified, fix is not yet in MAUS
    • Global:
      • Track-matching performance is slow for multiple spacepoints/tracks
      • Not much room for improvement from J. Greis' study
      • DR looking into processing schemes that will preserve fast MLCR reco while also incorporating global matching
    • MC:
      • TOF bug fix: in digitization, could potentially affect ~75 ps discrepancy between truth/reco MC
        • bug fix not yet propagated into mainline trunk
      • G4BL generation of pion beam libraries blocked -- issues with very few pions getting through to TOF1/Tracker.
        • Need guidance from analysis -- while waiting for resource to address the pion yield, is it still valuable to go ahead and generate 'muon' libraries and push through simulations?
  • Infrastructure
    • Survey from last run has been incorporated into geometry.
      • + a few other requests for extra virtual planes.
  • Data processing
    • Automatic offline reconstruction with latest survey, calibrations
    • To-do: Reprocessing of earlier runs with latest patch **
  • Personnel
    • DAQ head
    • Local DAQ expertise
      • EO & DR went through DAQ system in rack room
      • Further documentation on DATE implementation needed from YK
    • Geometry head
      • RB+DR interaction to document & detail geometry procedures has commenced.
