Outstanding problems

I chose to list and document here issues found during the Monte Carlo simulation production phase and the data reprocessing with GR-20-08-02, but also a few long standing issues that should now get fixed.

• General
  • slow: a factor of 2 slower than Pass7 release (not acceptable)
    • can't run more than 5k gammas or 10k bkg events on the long queue
    • can't reprocess more than 5k events per job (need 500 long queue jobs per run)
    • what can be turned off ? (Old profile, Acd1, ?)
    • what can be speed up ? (MST, CalClassify, New profile, Tree Based Tracking ?)
• Data reprocessing
  • Unguarded sort LPATE-73@JIRA: blocker (can't reprocess full data runs, crash for 1 event out of 500k)
  • other bug ? have to check more log files...
• MC Production
  • Geant4 exception LPATE-51@JIRA
    • unknown particles
    • alpha with too much energy (still a problem ?) LPATE-50@JIRA
  • Failed to write event to McTree LPATE-7@JIRA
  • other bug ? (some crashes in recent AG, same bug or new one ?)

Other known bugs

• See LPATE-84@JIRA
  • Errors in TkrEnergyTool in the TkrUtil package LPATE-85@JIRA
    • the UB2val[6] bug (instead of UB2val[9]): it should affect only events converting in layer2
    • the weight used to merge the parametric and profile is inverted. It affects all events.
    • That's why Tkr1ConEne and EvtJointEnergy are different between 1 and 10 GeV in 20-08-02.
  • LPATE-83@JIRA : The merit variable TkrNumTracks can only have values 0,1 or 2
• LPATE-91@JIRA: we can have CalEnergyCorr==0 when CalEnergyRaw>0.
• We do not always correctly take the 1st track in the all algorithms.
