Upgrade to RHEL7

  • Aim for week of Sept. 14th
  • David will contact Paul to schedule

ROL modifications

We discussed some modifications to the ROL (read out lists) that will be needed for the next run.

  • SYNC events
    • Alex will take care of implementing SYNC events and adding special information to data stream during these
    • David will implement parsing of this data in sim-recon to make it available for easy consumption
    • Among the data written out will be some pedestal information.
    • A system to update DAC settings on fADC channels in order to stabilize pedestals will be implemented
    • Beni has a private CCDB that was used to record/set DAC values. Some of this system may be applicable to the current project

L3 development

  • Rumors of Bryan M. having a secondary ROL capable of disentangling were clarified:
    • Bryan has single crate systems that implement disentangling on the crate
    • This system was modified from Hall-B code

DAQ

  • CODA 3.04 is now installed
    • Sergey will start testing
    • F1 and fADC125 still not well understood and ready for prime time. Work is ongoing.

Performance Document

  • Sean brought up that there is a GlueX Performance document on DocDB that has a section for DAQ that needs some numbers. Sergey F. volunteered (or was volunteered) to look at adding this.
