Minutes:

Attendees: Nathan B., Kishan R., Vardan G., Thomas B., Mike G., Torri J., Carl T.

• Announcements
  • Fortnight paper: There was a suggestion that EPSCI group every focus group (AI, SRO, FPGA based data transfer, etc.) will come up with a paper that would benefit their research.
  • Summer internship program: 5 high school students will be working with our group during the June-July time frame.
• Workshop and conferences
  • 3 accepted papers at VCHEP2021
  • TriDAS group will provide a presenter for the talk on TriDAS+JANA2 paper.
• CI + SPACK
  • Summer intern (Jillian) will work on the JLAB common environment.
• EIC
  • Graham informed on a new working group formation at the EIC, including David Lawrence, Christiano, and Dmitry Romanov.
  • Thomas reported that EIC will be able to submit jobs on OSG through newly created EIC sub VO on the JLAB OSG dedicated resources.
  • Brayan is going to increase fair share for the EIC VO, effectively treating EIC as a the 5th experimental Hall.
• JANA2
  • Nathan continues working on JANA2 GlueX port, and reported a sizable progress achieved last week.
• CLARA
  • v5.0.1 release is not officially deployed as a production version in CLAS12, so nothing to report.
• EJFAT
  • ESnet whitebox design is available for review. The design includes an option for a switch based load balancing.
  • ESnet suggest using hardware switches equipped with the LAB protocol, where multiple links between two switches combine to provide higher bandwidth links between them.
  • PR is being prepared for the FPGA.
  • FPGA from the ESnet will be available for tests mid July.

• Funding opportunities
  • Graham is leading multiple efforts to establish collaborations and projects with real funding opportunities, including an official collaboration with ESnet, ASCR funded 3 phase Data Reduction Pipeline project, and collaboration with BNL on AI model based workflows.

• SRO
  • Ed sent Vardan detailed instructions how to operate the SAMPA setup.
  • Vardan was able to start the readout and record data from 5 front-end cards in 10 separate files (2 stream per card).
  • Carl and Vardan are continuing to work on VTP and SAMPA setups in the indra-lab.
• CODA
  • Carl is finalizing the EVIO-6 release
  • Vardan is working on JCEdit to implement FPGA based ROC, a new CODA component type.
• AI
  • AI Experimental Controls
    • Torri is leading discussions at the AI WG weekly meetings related to defining critical design requirements and conditions for the project.
  • AICEG
    • Kishan continues to work with Nabuo on the AICEG project. He is evaluating Nabuo’s proposal to use a Lambda layer in the model that will help to incorporate user defined augmented features.
  • Hydra
    • Kishan he is trying to use layer-wise relevance propagation method to identify important sections of the histogram image.
    • Two summer interns will work on Hydra project this summer.
• OSG
  • Thomas reported that the new feature to bundle similar jobs in the mc-wrapper is chocking CONDOR when the number of bundled jobs in the queue is higher than certain amount (>2000 or so). An obvious solution to this problem, according to Thomas, would be to introduce a limit on the number of jobs in the queue.
  • Two summer students/interns will work on mc-wrapper this summer.
