Minutes:

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

• Announcements
  • Next Monday is holiday so no EPSCI meeting
  • Vardan submitted abstract for SEA's conference which includes some work from the end of the NASA/CLARA project
  • Thomas submitted an abstract to the AIRES2 workshop

• SRO
  • Feature requested by Dave A. (user script execution on rest, pause, and resume) has been tested and approved by Dave A.
  • Vardan will try parsing and processing of INDRA data this week
  • Able to compile SAMPA readout
    • modified code to make it operate in streaming mode
    • will test with cosmics

• CODA
  • EVIO-6
    • Using Disrupter-cpp fast ring buffer
    • installation instructions (need place to put documentation online at JLab)
    • Carl will look into making SPACK spec file

• CLARA
  • Feature request received for environment variable support to drive user packages
  • Feature request for individual timeouts for each service
  • Two bug reports:
    • possible name collisions. bug is understood and easily avoidable for now, but should be fixed eventually
    • "starts with" bug identified by Raphaella in xMsg package (not considered critical in CLAS12)

• JANA2
  • Big merge completed last week
  • Tests passed, though testing suite is not complete
  • Researched good Doxygen coding format and started applying to one JANA module (using how ACTS does it as a reference).

• EIC
  • Working on getting JLEIC field map into ACTS

• A.I.
  • Hydra currently processes ~3Hz w/ arond 2/3 to 3/4 of that time used for inference
  • Kishan will add performance section to Hydra paper (targeting CPC)
  • Will start work on vCHEP2021 paper
  • David needs to respond to Tanya and Cristiano about AII preproposal
