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( Michael's notes)
  • ESnet whitebox design is available for review. The design is based on FPGA acceleration on the compute server side and network switch-based load balancing on the DAQ side but also includes an option for DAQ side FPGA acceleration.
  • ESnet suggest using hardware switches equipped with the LAG aggregation protocol, where multiple links between two switches combine to provide higher bandwidth links between them, however initial testing could be based on non-LAG supporting switches.
  • PR is being prepared for the FPGA.
  • AVNET (vendor) has requested reestablishing recently expired NDA.
  • Expect that FPGA from the ESnet will be available for tests no earlier than 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.
