Agenda

  1. Announcements
    • Alex A. reported that the Second Production Run is running full speed ahead, with 65% of batch 1 completed, which is expected to be completed by Friday. Production started Saturday afternoon after some last minute enhancements and bug fixes, and has run with up to ~6000 cores utilized.
    • Elton reported that the solenoid was ramped up to 1350A and was running fine as of 10 minutes before the meeting. If all goes well, this will be the planned setpoint for the Fall run.
    • Sean reported that the new EVIO parser had shown some minor potential issues with the EVIO skimming code, which he is tracking down before committing his changes. As reported previously, these changes enable targeted skimming of the data which drastically reduce skim size on disk and increase performance.
  2. Collaboration Meeting
    • Sean will give a calibration overview talk, and a requested talk on detector performance will be planned as well. The schedule will be firmed up at the offline software meeting.
  3. Run Planning
    • Data taking
      • Cosmic data taking is waiting on Alex S.'s upgrading of the firmware on all crates. The latest update is that it should be done by this coming Monday.
      • About 2 hours of Beam data at the start of the fall run is planned to be taken to recommission calibrations and the new data formats.
    • The output of the new fADC250 firmware will need to be tested offline. The latest news is that David has a spec to implement in the EVIO parser(s).
    • ROOT 6 transition - no one has tested their code with ROOT 6 yet. Mark I. said that there may be problems with his JLab builds, and is investigating. Sean had noticed that RooFIt was not being installed, although it was apparently enabled in the build.
    • Calibrations to run
  4. Calibration Updates
  5. Simulations
    • Data/Simulation comparisons
      • BCAL (Will M.)
      • FCAL (Adesh)
      • CDC (Mike S.)
      • FDC (Alex A.)
      • Tracking (Paul/Simon)
      • TOF (Beni)
