Agenda:

1. Previous meeting

2. Announcements:
   1. NERSC-ESnet-JLab on-site workshop Jan 31 - Feb 1
   2. Manuscript ESnet / JLab FPGA Accelerated Transport (No. TNS-00484-2022.R1) FINAL version submitted for publication to IEEE Transactions on Nuclear Science (TNS).
   3. Final version of RT2022 EJFAT/IEEE-TNS submitted 02/07/2023
3. Current Test set-up:
   1. CLAS12 files -> Carl C++ Packetizer -> LB -> Carls's C++ Reassembler -> ERSAP
4. NERSC Test set-up:
   1. Data Source: ? pre-event aggregated?
   2. Derek Howard (ESnet) to build CP for EJFAT and Perlmutter at NERSC with JLab assisting
      1. Proposed protobuf schema
         1. Assumes PID loop inside CP - but willing to change.
      2. Week of 2/6: Other ESnet projects - mtg 4PM Thursday
      3. Week of 2/13:
         1. Finish mock API server
         2. create an internal representation of the load balancer calendar
         3. implement the algorithm specified in "EJFAT Load Balancer Schedule Density from Reassembly Engine PID control"
      4. Week of 2/20: Other ESnet projects
      5. Week of 2/27: Add integration for the SmartNIC P4 Controller, synchronizing the internal state of the gRPC server with the P4 tables.
      6. Week of 3/6: Other ESnet projects
      7. Week of 3/13: Start work on integration test tooling.
   3. Data Sink:
      1. Perlmutter
      2. SPIN
      3. ERSAP
5. Resources:
   1. CP gRPC i/f to RE PID: Non-streaming / Peer-to-Peer (Note on gRPC Publish/Subscribe)
   2. CP PID signal -> LB Schedule Density transform (Draft C++ algorithm completed)
   3. Proposed Changes to RE Meta-Data
   4. CP gRPC i/f to LB (pending)
6. Status
7. AOT
