    • Fix memory leaks
    • Tracker -- Kalman updates
    • Updated tracker noise
    • execute_against_data.py should be always make a tarball

Online Reconstruction

Batch Offline Reconstruction

  • GRID running 1.0.0
    • Enable MC GRID running again #1739
    • execute_against_data.py to always produce tarball Is this still relevant?

Performance

  • Speed improvements
    • Fix memory leaks - preventing GRID running (A. Dobbs, D. Rajaram, C. Rogers)

Release Status

  • MAUS 1.1.1 to be released as soon as D. Rajaram provides a final TOF update and CKOV onrec bug fix merged in

Schedule

  • Updated schedule now ready to go to Alan Grant

Detectors

  • KL
  • Ckov
  • EMR
  • Tracker
    • R. Bayes is also seeing odd tracker track locations, even with updated CDB geometry
  • TOF

Global Reconstruction

  • Still waiting on working C++ reducer example
  • RK dE/dx almost done

Monte Carlo

Geometry

  • KL CDB geometry needs to be checked over by M. Bogomilov, A. Dobbs to email him
  • SciFi CDB geometry looks good but should be checked by tracker folk running through MAUS
  • Last TOF update to go in, issue #1752

Online Reconstruction

  • TOF reducer currently using up 100% of CPU, D. Rajaram investigating
  • New OnRec framework has a few glitches, C. Rogers job
  • CKOV plots bug fixed in control room branch, A. Lui to provide A. Dobbs with a branch to merge into merge branch

Batch Offline Reconstruction

  • Almost there with enabling GRID MC running again, should hopefully be back before CM (need scifi and KL geometry verfied, and last TOF geometry update)
  • Batch offline recon currently being performed on onrec03, works smoothly but not yet fully automated
  • New dedicated offline recon machine on the way

Infrastructure

  • Replace TRefArray with with std::vector<TRef> (probably encapsulated in some class) to enable multi-threading (A. Dobbs)
