Minutes:

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

  • Licenses
    • CLion licenses expired. Quote for renewal received and is in the works.
    • GitKraken licenses recently auto-renewed. It seems only 2 people may use GitKraken occasionally. (David will check on adjusting licenses)
    • Overleaf licenses are expiring. Will like go to purchasing individual licenses since it does not look like enough use to justify a site license.
  • EIC
    • Nathan has been working with Sylvester and Whit at ANL to understand their GAUDI-based software in order to gauge how difficult it will be to port it into JANA2
      • Fairly complex CI system using Docker to build their software
      • Most of their Docker images not accessible outside ANL. One image copied to dockerhub for Nathan to work with
      • GAUDI uses a "gaudi cmake" that deviates from standard cmake so some effort is required to move to a standard cmake build system
      • One goal is to get a document on migrating from GAUDI to JANA2 that we can post on the JANA2 website.
    • Communication from Pukai's mentor listing several issues with eJANA. These mostly appear to be things on Dmitry's side.
  • CLARA
    • New version released for use by CLAS12
      • Includes fix for bug that caused rare occurrences where a file was only partially processed
  • JANA2
    • Nathan working to integrate JANA2 and CLARA (i.e. ERSAP).
  • EJFAT
    • Met several times with ESnet for low-level design discussions
    • ESnet presented us with what looks to be a complete design for phase-I
    • A single U280 is needed for phase-I with some load balancing handled by that which is already integrated into the switches
    • Mike will look into putting a PR in for the U280 (will need to learn the JLab procurement system)
    • Existing switches at JLab may not support protocols needed by ESnet software. Dave A. is looking into what we need to purchase.
    • ESnet cannot start work on FPGA software development until May 15th so delivery not expected until maybe July.
  • SRO
    • Contacted Ed J. about SAMPA setup in INDRA lab
      • Gas bottle for GEM changed last week. Needed to flow for a couple of days before turning on HV
      • Ed will go in Thurs. or Fri. to power system up. Vardan volunteered to help if needed.
    • VTP testing now includes Data Lakes
      • Increased resident memory usage to 22GB
      • Slight decrease in CPU usage to around 13 cores
    • Vardan working on JAVA bindings in ERSAP
  • CODA
    • Dave A. is working on presenting data read from the VTP as a ROC to the standard CODA system
      • This requires updates to jcedit which Vardan is working on
      • This will be deployed as part of CODA 3.11
      • Will be for triggered mode only (SRO support will not be included yet)
  • AI Experimental Controls
    • Torri able to run GlueX CDC calibration codes on farm
    • Naomi suggested several tasks involving GARFIELD to allow calculation related to pressure changes
    • Suggestion was made to build GARFIELD in central location on the CUE (with spack)
  • FOAs + LDRD
    • 3 ASR, 1 NP, and 1 LDRD
    • Graham listed our involvement in several of these:
      • Accelerator operations: Chris T. and Malachi S.
      • Modeling computation and predicting data flows (smart data center): BNL + JLab
      • MCGen : Nobuo + ANL
      • Data reduction/Filtering: JLab + ORNL + GA Tech
      • EJFAT (different funding channel): JLab + ESnet
    • LDRD proposals
      • Thomas noted pre-proposal template is short and due May 5th. Full proposals due at end of May.
      • Amplitude Analysis: Thomas
      • Surrogate Models: Kishan, David ,...
  • Offsite Computing
    • GlueX proposal to XSEDE for time on PSC Bridges-2 submitted
    • OSG
      • Operations improved after unmounting lustre and home from scosg16
      • scosg20 up, but not in production use yet
      • MCWrapper: Thomas working on bundling similar jobs which has the potential of speeding up the submit times by factors of 20-40.
