Minutes

Attendees: David L., Vardan G., Jeng T., Cissie M., Nathan B.

• Nathan reported on effort to process CLAS12 SRO packet data with JANA
  • Stubs in place for filter components
  • integrated use official EVIO library
  • The checklist in Github issues needs to be updated

• Cissie reported on logging process telemetry on ifarm via podman/docker
  • While podman currently works on ifarm, it does not yet work on slurm farm nodes
  • Some flow charts of some data flow examples on JIRIAF were shown
  • Logged into clonfarm21 to better understand system there for streaming. Needs more input though on how streaming works from there.
  • Some discussion on setting up the streaming work flow using individual apptainers on farm as opposed to running all in one apptainer
    • Jeng noted that the process_exporter should work in this case

• Vardan reported briefly on DPUX development
  • DPUX is in a git repository
    • Link to repository needed on RTDP main page
  • Jeng will work with Vardan on implementing configuration in issue 34

• We had some discussion on how Prometheus works in regards to permanent and temporary storage
  • Question from David: Can the DB from running a particular workflow be saved easily to files for archival purposes and then easily resurrected by starting up a Prometheus container and pointing it to the DB files?
    • Answer: yes

Action Items

1. Update checklist in Github issues (Nathan)
2. Try running podio example using apptainer on slurm farm (Cissie)
3. Add link to DPUX repository on RTDP wiki page (Vardan)
