- EJFAT VLAN Open for Business:
  - Hosts running Ubuntu 20.04
  - 1 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

    - 172.19.22.242 - Currently reserved for Stacey
    - 172.19.22.247 - Currently reserved for Mike
  - indra-s2 upgraded to Ubuntu 20.04 LB sucessfully installed, now on EJFAT VLAN / DAQ lo-speed networks via Indra-Lab switch
  - ejfat-1 reserved for Carl
  - ejfat-2 reserved for Stacey
  - /daq-fs/gyurjyan self-contained ERSAP event processing package
- 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

  - cpusets
  - Pktgen-DPDK
  - Receive Side Scaling
  - Packet Loss Studies / LB Round Robin Studies - migrated 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
- EJFAT VLAN Infrastructure
  - Test plan for all pieces required for rnd-to-end test
  - Control Plane
  - Demonstrate CP based flexibility/elasticity
  - SLURM env for EJFAT VLAN (Hess)
- Vivado Licesnses for new machines - AI/ML ? D. Lawrence POC
- Open Nic Shell
- ACAT 2022 - October 24 / Italy - accepted for Oral Presentation
- RT2022 Oral Presentation on August 5
- RT 2022 Paper - submitted August 22 - up to 8 mos. review process
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
AOT

Notes:

numa tools on ubuntu:
- sudo apt install hwloc-nox
- sudo apt install numactl
lstopo
numactl --hardware
To control the scheduling class, you can use the chrt command.
To pin to CPUs, use the taskset command. Or use the underlying syscalls.
kernel dameon threads
- handle NIC driver interrupts
- set scheduling class to SCHED_FIFO / SCHED_RR of reassembly process
want to set cpu socket of reassembly in common NUMA domain as NIC
