Computing & Software status, October 17, 2017¶

• Software:
  • Tracker:
    • Efficiency:
  • Tracker rolling review continues, several actions worked on -- cut optimization, implementing MCS errors. Next meeting end of the week
  • Globals:
    • Speed mitigation: CR implemented geometry lookup table, speeds up by ~25%, seems to be significant overhead from MAUS outputter
    • Outputter can be sped up by avoiding data conversion; meanwhile plan is to trigger two jobs for each run in MLCR -- "fast" without globals, and a full reco with globals.

• MC
  • TOF issues: stands. Need a follow up with SW.
  • 7469 MC shows an offset of ~150ps in e+ between data and MC

• G4BL
  • PF studying disagreements with data, production model -- awaiting a new version of MARS

• Geometry:
  • Bug in LH2 geometry description -- lh2 not filling the vessel fully
  • Alignment for 2017/01 -- re-done, changes are very marginal

• Processing:
  • Ne MC to be done
  • GRID user framework is changing [ no more WMS ]. For MC, Ray and Dimitrije have been testing a new framework. For real-data reconstruction, requires significant changes to keep GRID submission system alive. JM looking into it.

• DAQ/Online:
  • Tracker calibration in progress.
  • Tracker veto timing not optimal

• Controls:
  • Alarm handler greatly improved, handful of false alarms during stable operation

• MAUS Paper
  • Comments from KL to be incorporated.
