Minutes

Present:

  • JLab: Alex Barnes, Mark Dalton, Mark Ito (chair), David Lawrence, Paul Mattione, Curtis Meyer, Eric Pooser, Matt Shepherd, Justin Stevens, Simon Taylor, Beni Zihlmann
  • NU: Sean Dobbs

Announcements

  1. Sim-Recon 1.3.0. Mark reminded us of the latest release. It is compatible with JANA 0.7.3 and uses a new BCAL smearing scheme from Tegan Beattie.
    • CLHEP is no longer needed by AmpTools and comes packaged with Geant4 in recent versions. It will be dropped from the packages built by default by the GlueX Version Management System (GVMS).
  2. Legacy build directories. Some old directories in the /group/halld/Software/builds directory at JLab are about to disappear. Lately they have been a source of confusion. See Mark's email message for details.

Review of minutes from June 24

We went over the minutes from last time.

  • The switch to the new volatile disk hardware went without a hitch.
  • The Data Center power outage went well as well.
  • Mark I. is still promising to send out instructions on how to switch from use of one of the various builds of GlueX software to another.
  • Mark and Beni have succeeded in building the complete suite of GlueX software on Beni's Ubuntu machine. The next step is to set up a nightly build.
  • Beni has succeeded in creating a working build of GlueX software against a version of ROOT 6. We will need to discuss an upgrade in the future.

Offline Monitoring Train Schedule and Status

Paul reported that the plan is to launch the next offline monitoring train this Friday. There was no train last week.

Sean gave us an update on offline monitoring post-processing. His slide reads as follows:

Offline Monitoring Backend

  • The system is ready for the next run
  • Memory usage under control - ~1 GB per process
  • pylint is your friend
  • Parallelized hadd - phadd
    • Uses python thread pooling
    • Current settings: 6 threads, 10 files in a batch. On ifarm, limited by bandwidth to work disk
    • Run 2439: ~40 min (hadd) -> ~14 min (phadd)
    • N.B. hadd -n processes batches serially, uses less memory but slower
  • Ready to monitor simulations
  • Processing of online histograms works now, too

He also mentioned:

  • The next step is a webpage to show results.
  • We need a similar set of procedures for simulation.
  • We should think about running something for the online as well.

Spring 2015 Commissioning Simulations

Sean updated the status of the simulation effort.
