Minutes:

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

• GPU Farm nodes
  • Some complications with initial plan for GPU purchase by ENP for SciComp farm
  • Vendor quote for GPU nodes does not include option for single GPU nodes with reasonable pricing (only nodes with many GPUs)
  • Alternative plan formed to purchase only a couple of those nodes, but Bryan was going to look into getting quote from another vendor

• OSG
  • There was a request for suggestions for Edgar's replacement. Raised question if person being integrated now will be temporary.
  • Thomas believes this person will remain our contact and any additional hire they make will work on other things.

• SPACK
  • Some work done on documentation on wiki
  • Instructions pointed to for using the system

• ACTS
  • Met with Andrei Salzberger last week (lead developer for ACTS)
  • ACTS is now in use for production in ATLAS
    • Released version 6 two days ago
    • May be good time to finally update from version 1.2 EIC is currently using since production use at ATLAS may slow down API-breaking major version releases
  • Need to reach out to Pukai (edge customer) again

• JANA2
  • Some progress in getting scons build system working again with GlueX + JANA2
  • JANA2 + ERSAP development is ready to start. ersap-jana project already on GitHub (Vardan)

• CLARA
  • Responsibilities for I/O code now transferred to CLAS12 developers

• Data Transport
  • Mike, Graham, and David Met with Yatish Kumar from ESNet to discuss FPGA data transport project
  • Yatish indicated we would need an FPGA programmer on our end
  • Meeting scheduled for this week with Chris Cuevas and some of his group to discuss the project

• INDRA-ASTRA project
  • Current request/plan is to get SAMPA system setup so they can continue from where they left off when Eric P. initially set up project
  • Vardan noted that the VTP setup may be more readily available and could be useful for their purposes.
  • David will reach out to Markus to discuss it

• AI
  • AIEC (Experimental Controls)
    • Paperwork for the 2 new hires for the project has been submitted. Offers have not been extended/accepted yet
    • Thomas has begun spending more time on the project. (He charges 10% of his time to it)
    • Initial focus is on existing GlueX CDC calibration code
  • Hydra paper
    • First draft complete and primary authors have been notified
  • JupyterHub
    • Some issues with using a virtual environment
    • Need access to log files to track down issue
    • epsci-notebook works better, but not all tab completion features are working. It does use Jupyterlab-3.
  • AiDAPT (Nobuo project)
    • Kishan converted some notebooks to use more recent TF and Keras version
    • Notebooks had used older version of TF before Keras was integrated
  • Some review of the GlueX BCAL project to classify Neutronic vs. photonic showers
    • Will need to study more and communicate with project owners again about next steps
