Summary of Actions

  • ACTION: Look into TRefArray limits (A. Dobbs)
  • ACTION: Fix tracker unpacking and digitisation (E. Overton, P. Kyberd)
  • ACTION: Flag low pt for downstream tracker reconstruction (A. Dobbs) Done in personal dev branch, needs testing before merge
  • ACTION: Optimize momentum residuals for final tracks (C. Hunt)
  • ACTION: Get detector output in global coordinate system (C. Heidt, C. Hunt)
  • ACTION: Need uncertainties from detector reconstructions: on positions, momenta, tof time (A. Dobbs)

  • ACTION: Pursue uncertainties from TOF and global coordinate transform (A. Dobbs)

Agenda

Release status

  • Current release = 0.9.5
  • Targets for release 0.9.6:
    • Tracker online plots
    • Build system improvements
    • Unpacker bug fix
  • Targets for future release:
    • execute_against_data.py should be always make a tarball
    • Trigger MC
    • Tracker -- pat rec and kalman updates
    • Tracker unpacking and digitisation fix
    • Faster API

Schedule

Detectors

  • Detector integration (D. Rajaram)
    • Reconstruction quality flags (A. Dobbs to make requests to detector groups) #1585
  • Tracker (P. Kyberd)
    • Space-point, track-finding efficiency studies partly blocked by lack of trigger #1182
    • ACTION: Tracker unpacking and digitisation fix (E. Overton, A. Dobbs)
    • ACTION: Flag low pt for downstream tracker reconstruction (A. Dobbs) Done in personal dev branch, needs testing before merge
    • ACTION: Optimize momentum residuals for final tracks (C. Hunt)
  • TOF (D. Rajaram)
    • Restructure TOF MC Digitizer - part of trigger MC (D. Rajaram)
  • EMR (F. Drielsma)
    • MC #1033
      • ACTION: Refactor code to remove extra recon events (F. Drielsma) Done, in trunk
  • KL (M. Bogomilov)
    • STANDING: MC validation, optimization, tuning, #1411
  • CKOV (Drews, Winter, D. Rajaram)
  • Monte Carlo trigger (D. Rajaram) #1182
    • ACTION: Restructure TOF Digitisation and incorporate MapCppTrigger (D. Rajaram)

Global Reconstruction

  • Tracking (J. Greis)
  • PID (C. Pidcott)
  • Detector output
    • ACTION: Get detector output in global coordinate system (C. Heidt, C. Hunt)
    • ACTION: Need uncertainties from detector reconstructions: on positions, momenta, tof time (A. Dobbs) Update - emailed detector owners, CKOV replied, EMR now implemented and in trunk, no other responses
      • Will also need data structure modifications once we understand how to get the uncertainties

Unpacking

  • Need to roll out SL6 to Jenkins nodes (P. Franchini)
    • Configure to run with either Step I or Step IV unpacker depending on environment flag, see #1633. Done
    • Need to configure a Jenkins build to regularly check Step I data once we move to the Step IV unpacker as default
  • ACTION Fix tracker unpacking and digitisation (E. Overton, P. Kyberd)
  • DAQ channel maps to DB (D. Rajaram) #1375, blocked by #994

Infrastructure

  • Geometry/MC (S. Ricciardi, R. Bayes)
    • Speed improvements (R. Bayes)
  • Monte Carlo
    • ACTION: Upload script feature (R. Bayes)
  • GRID and Batch Production (C. Rogers, J. Martyniak)
    • Try grid running again? #1489
      • Running 0.9.5
    • execute_against_data.py
  • Code deployment
  • Documentation
  • Data Structure

Online

Performance

  • Speed improvements
    • No more passing JSON between modules, as string conversions are expensive, only use JSON for configuration data and input / output (A. Dobbs, D. Rajaram, C. Rogers)
      • Extensive refactor work
    • YK proposes parallelising MAUS with C++11 multi-threading, at the mapper level, see #1638 (A. Dobbs, D. Rajaram, C. Rogers, Y. Karadzhov)
      • Extensive refactor work
  • Beam generation excessive resource usage
    • Query analysis group requirements (in particular how many G4BL beams we need)
    • Consider alternative upstream beam generation code

Documentation

  • Create workbook (A. Dobbs) attachment:MausWorkBook.pdf

AOB

  • MAUS paper draft - developers please review and supply input where required launchpad

Detectors

  • Detector Integration
  • KL
    MC has been stable, to sign off after PID paper converges
  • Ckov
    DR to merge Miles Winter's Ckov code merge, pending tests
  • EMR
    DR sees what looks like an extra recon event, with just an emr_event, when running reducers. Need to verify and have FD remove it if it's still there
  • Tracker
    Chris Hunt working on getting improved Kalman into MAUS this week
  • TOF

Global Reconstruction

  • Have upstream and downstream matched tracks
    Looks promising using mean energy loss
    Waiting for RK dE/dX from MU

Unpacking

Unpacking/data corruption issues with VLSB data, YK looking at it.

Infrastructure

  • Geometry
  • MC
    RB debugging execute_against_mc to read cooling channel parameters etc from DB
    Previous processing on Glasgow cluster did not interface with CDB for currents
  • G4BL
  • GRID
