Agenda:

1. Previous meeting

2. Announcements:
   1. Computer center power outage 06/20/2023 Rescheduled
3. NERSC Test Development:
   1. Data Source:
      1. JLAB, CLAS12, pre-triggered events - 1 channel
      2. Front End Packetizer pending mods for Tick-sync msg to CP - UDP packet to port on CP Host
   2. Derek Howard (ESnet) to build CP for EJFAT and Perlmutter at NERSC with JLab assisting
      1. Week of 6/18: Derek out through 6/21
      2. Local Installation of ESnet CP - in progress - requires new FPGA f/w (in progress)
   3. Data Sink:
      1. Perlmutter
      2. ERSAP
   4. Networking for Test
      1. L3VPN Design with ESNet
      2. Vet the cybersecurity controls with the security group.
      3. Implement Local network configuration changes/cybersecurity controls
      4. Configure L3VPN, establish peering next
      5. Relocate to HACS-4 - soon
      6. Configure hosts to use tunnel, confirm traffic flow is as expected - last
   5. JLab Preliminary NERSC Test
   6. Test Plans - JLab, ESnet, NERSC:
4. Hall B CLAS12 detector streaming test - expecting to meet with Sergey B., D. Abbott on Thursday
   1. Issues for Thursday meeting:
      1. Number of streams
      2. Bandwidth per stream
      3. Test mode for VTP and/or real data. (Real data here may mean ready from detectors, but thresholds set low so as to trigger on noise).
      4. Bandwidth from Hall to Counting House
      5. Bandwidth from counting house to compute center.
      6. Status of Hall-B U280 order - will EPSCI need to supply one?
   2. Switch 7050 is expected to arrive some time around October; we have already transceivers, short cables and patch panel to connect up to 32 VTPs to it using two 10GBit links per VTP
   3. Fiber installation between hallb forward carriage and hallb counting room should be done this summer, will be enough for 24 VTPs using two 10GBit links per VTP
   4. We have only one fiber between hallb counting room and counting house second floor available right now, will order more fibers installation, may take several months
   5. There are several available fibers between counting house second floor and computer center (like 6), we can use a couple of them for our test
   6. Summary: sometime in October, we should have 48 10GBit links from 24 VTPs connected to the switch in hallb counting room, with that switch connected to computer center by 2x100GBit links
5. RT2022 Paper: Submission Process Complete
6. ACAT2022 Paper: - submitted
7. CHEP 2023 Conference Publication - in progress - deadline September 8, 2023
8. Simulation
   1. Use FIFO Levels
   2. Use EPR
   3. Use FIFO Levels/Disbursement
9. Demo Ready EJFAT Instance
10. EJFAT Operational Status Board -> Prometheus Reporting
11. Resources:
    1. HPDF
12. AOT
