Agenda:

  1. Previous meeting
  2. Announcements:
    1. Computer center power outage 06/20/2023 Rescheduled
    2. Moved ejfats, indra-s2 to new racks / networks
    3. ejfat-2 LB FPGAs on-line pending testing
    4. All system except ejfat-2, indra-s2 still reporting pcieport ... no space for [io size 0x1000]
  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. Derek now full time on EJFAT
      2. Local Installation of dynamic ESnet CP (ejfat-2) - complete
    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
      6. Configure hosts to use tunnel, confirm traffic flow is as expected - last
    5. JLab Preliminary NERSC Test
      1. Vardan's Metrics/Horizontal Scaling - static LB
      2. Preliminary Testing: New LB f/w and CP
    6. Test Plans - JLab, ESnet, NERSC:
  4. Hall B CLAS12 detector streaming test
    1. 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
    2. 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
    3. 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
    4. 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
    5. 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 - Derek H./ESnet to assist - 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
