Minutes:

Attendees: David L., Carl T., Nathan B., Kishan R., Vardan G., Thomas B.

• Announcements
  • Kishan is flying in on Feb. 19th
  • 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
    • David will work with Igal to diagnose

• SRO
  • Joint ERSAP + TriDAS meeting last week
    • Vardan has been in communication with Carmello on integrating ERSAP and TriDAS
    • Will meet with TriDAS group every other week
  • SAMPA chip readout
    • Still waiting on hardware guys to get INDRA setup back online
    • Vardan will contact Ed, Holly, and Alexandre C. to coordinate efforts

• CODA
  • Vardan asked to recompile CODA components using JDE15
  • 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.
  • JANA2
    • Nathan working with Vardan to get JANA2 to compile in his (cmake) build environment
    • Nathan is working on code to autotune NUMA parameters

• Experiment support
  • EIC
    • Nathan will be meeting with Dmitry and some students this week to discuss handing off what he has achieved so they can carry it forward into the physics reconstruction code.
