    • Vardan's abstract for SEA was accepted. (He just needs to choose preferred time slot.)
  • Group policy on papers
    • We discussed briefly what the EPSCI group policy on authorship of papers should be
    • The JLab DAQ group had a policy of putting everyone in the group's name on every paper they produced. The principal authors' names were listed first
    • There was some discussion as to whether we should adopt a similar policy for EPSCI or decide a'la carte
    • Consensus was that we should adopt this policy.
      • Everyone's name goes on every paper produced by group, regardless whether they had significant involvement in the work
      • Anyone may opt-out of having their name on a paper
      • Principle author's names will go first.
  • A.I.
    • Draft of Hydra paper for CPC is essentially complete
    • Draft of Hydra paper for vCHEP2021 is still just getting started
    • Complete draft of Thomas' of Early Career Award proposal is done. (A.I. is a component of it)
    • Kishan reached out to a couple of people regarding their ongoing AI projects as presented at the Town Hall meeting at the end of last summer. He will meet with Zisis and Cristiano a week from Friday on 2/12


  • Offsite data processing
    • GlueX is in production at NERSC
    • Some issues with job rates at new PSC Bridges-2 facility during the onging Early User Program

    • Carl working on "spacking" CODA components
  • Analysis Frameworks
    • CLARA
      • Vardan requested to build components with JDK11 as CLAS12 has seen a 20% performance improvement with that.
      • JDK8 compiled components will be kept around. Need settings to easily allow user to select which to use.
      • Report of minor bug where 1% of time processing halts after processing 1st or 2nd item. Vardan has some clues as to what is going on, but will need to investigate more. Not causing any work stoppage.
