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.
