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. Current Test set-up:
   1. CLAS12 files -> Carl C++ Packetizer -> LB -> Carls's C++ Reassembler -> ERSAP
4. New Test set-up (pending):
   1. CLAS12 files -> Carl C++ Packetizer -> new LB (delivered) / dynamic CP (in progress) -> Carls's C++ Reassembler -> PID controller (completed) -> ERSAP
   2. RE input fifo 50% full as PID set-point for Schedule Density
5. Derek Howard (ESnet) to build CP for EJFAT and Perlmutter at NERSC with JLab assisting
   1. Proposed protobuf schema
   2. Week of 2/6: Other ESnet projects
   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.
