Previous meeting
Status:
- Using ESnet FPGA f/w build 28 April
  - Specs
  - Jumbo Frames
  - arp, ping, ICMP filtering
  - Port entropy
- IPV6 neighbor discovery
- LB F/W Installation Manual - with PCI buffer allocation assurance steps
- Script based LB Control Plane
- In ESnet Legal Review
  - Support C libraries for LB Host Control Plane
  - ESnet smartnic open-source GitHub repo - in legal review
  - ESnet private, forkable Jlab P4 and simulations GitHub repo - in legal review
  - FPGA LB data generation capability
- ERSAP feed end bottleneck needs investigation; Timmer/Gyurjyan investigating
- EJFAT VLAN Open for Business:
  - Hosts running Ubuntu 20.04
  - 10 Gbs i/f are: ejfat-1, ejfat-2, ejfat-3, ejfat-3, ejfat-5, ejfat-6, ejfat-fs
  - 100 Gbs i/f are: ejfat-1-daq, ejfat-2-daq, ejfat-3-daq, ejfat-3-daq, ejfat-5-daq, ejfat-6-daq, ejfat-fs-daq
  - LBs: 172.19.22.241-247
- Spare EJFAT equip loaners:
  - (4) DAQ dev machines indra-s[1-3] 129.57.29/109.23[0-2]
    - alkaid: 24 Xeon Gold 3.4 GHz cores, 100Gbs
    - indra-s1: 24 Xeon Gold 3.0 GHz cores, 100Gbs
    - indra-s2: 32 Xeon Gold 3.2 GHz cores, 100Gbs
    - indra-s3: 32 Xeon Gold 2.3 GHz cores, 100Gbs, 750GB ram disk
  - (4) DAQ Farm machines dafarm6[1-4] currently on 129.57.29.17[1-4] - each 32 Xeon 2.0Ghz cores - 1 Gbs NIC + (4) 10Gbs Spare NICs
  - (4) Unbuilt DAQ Farm machines - each 32 Xeon 2.0Ghz cores - 1 Gbs NIC + (4) 10Gbs Spare NICs
- ~~PR408549 (7) 100Gbs NICs~~ - Installed in Compute Center / EJFAT / EJFAT VLAN

Next Steps:
- FireHose Benchmark

  - cpusets
  - Pktgen-DPDK
  - Receive Side Scaling
  - Packet Loss Studies / LB Round Robin Studies - migrating to Compute Center / EJFAT / EJFAT VLAN
  - DAQ/VTP Data Generation Test Harness - 40 Gbs initially - after FEG
  - Host NICs
  - Host S/W Reassembly - better algorithms, buffering, asynchronicity, etc.
  - EJFAT UDP Transmission Performance
  - Need better parameters for event reassembly/reconstruction
  - DPDK will own NIC bypassing kernel, etc. - ESnet reports can stream 100 Gbps using DPDK; Pktgen-DPDK
  - Look at ROCE / NIC
- SPDK for hyper storage performance
- ESnet UDP tuning
- Control Plane
  - Will interact with SLURM / Kubernetes
  - Python based (?)
  - Control Plane daemon for compute host (?)
  - Demonstrate CP based flexibility/elasticity
  - SLURM env for EJFAT VLAN (Hess)
- Vivado Licesnses for new machines - AI/ML ? D. Lawrence POC
- Open Nic Shell

- RT2022 Oral Presentation on August 5
- RT 2022 Paper - submitted August 22
Back Burner / Downstream:
- Hall-B FT calorimeter and hodoscope streaming readout test
  - May be able to use Abbott's indra-s1 setup
  - May be able to use new VTP f/w with Hall-B VTP's
  - CODA 3.10 + ERSAP for new VTP f/w
  - CODA 2.0 (non-streaming) for old VTP f/w
  - Diagram
  - Hall-B to start taking data June 8
  - Hall B VTPs on .167. subnet
- HOSS
  - parallelize writing of raw data files
  - distribute raw data across multiple compute nodes for calibration skims
  - 1 Gbs at hi-luminosity
  - Hall-D comms with DAQ 109 subnet require network customization; (EJFAT subnet)
  - Hall-D EJFAT use case
  - Hall-D EJFAT Network Diagram
- IPV6 testing
