Agenda:

Previous meeting
Situation:
- ~~Testing with End-to-end EJFAT ERSAP solution on FPGA LB~~
- ~~Jumbo Frames - indra-s2,s3, alkaid, fpga~~
- Linux IP stack buffer size increased
- Using script based LB Control Plane
- ERSAP feed end bottleneck needs investigation; Timmer's blaster may provide relief
- EJFAT subnet
  - VLAN 937 172.19.22.0/24
  - 10Gbs NIC, but need cables (copper twinX will do)
- DAQ Farm machines dafarm61 dafarm62 dafarm63 dafarm64 currently on 129.57.29.0/24 subnet w/ additional i/f available for EJFAT subnet
- Testing newly received FPGA load
  - Specs
  - arp, ping - working
  - Issues:
    - Port entropy field - currently broken, update pending
    - MTU size restricted to max 1500, update pending
    - Possibly incorrect control message responses being investigated
  - Rec'd new f/w build 28 April
Pending:
- Compute Equip.- ETA 1 June - sans 100Gbs NICs (ETA 1 July)
- Networking Equip. - ETA ~~1 July~~ 5 October
- Support C libraries for LB Host Control Plane
- ESnet smartnic open-source GitHub repo (April)
- ESnet private, forkable Jlab P4 and simulations GitHub repo (April)
To Do:
- Near Term:
  - Hall-B FT calorimeter and hodoscope streaming readout test - Pending OK from Sergey B.
    - May be able to use Abbott's indra-s1 setup
    - May be to use new VTP f/w with Hall-B VTP's - (Ben Raydo)
    - CODA 3.10 + ERSAP for new VTP f/w
    - CODA 2.0 for old VTP f/w
  - HOSS Hall-D EJFAT use case
    - parallelize writing of raw data files
    - distribute raw data across multiple compute nodes for calibration skims
    - 1 Gbs at hi-luminosity
    - Control Plane
      - Feedback from Compute hosts
      - Control Plane daemon for compute host
      - Demonstrate CP based flexibility/elasticity
    - Hall-D comms with DAQ 109 subnet require network customization; DAQ 29 subnet available
    - Slides
    - Netwok Diagram
- Downstream:
  - DPDK
  - IPV6 testing
  - RT2022 - August 01-05 Conference

 ** Near Term:
 *** Hall-B FT calorimeter and hodoscope streaming readout test - Pending OK from Sergey B.
-**** 2 crates for FT calorimeter, furnished with fADC250s. Total 332 channels.
-**** 1 crate for the hodoscope that has 12 fADC (total 192 channels)
-**** Update firmware on all 3 VTPs to send fADC aggregated data frames in the EVIO format, through UDP.
-**** Design ERSAP FE application containing an actor that receives VTP frames through UDP, extracts information about the source/data ID and frame number (tick), and sends it to the EJFAT packetizing engine.
-**** Stage 1 testing:  single stream/data-ID
-***** EJFAT LB + reassembly (RA) engine overall performance data-rate dependence.
-***** EJFAT LB + RA engine performance dependence from the EJFAT packetizing engine MTU settings
-**** Stage 2 testing: multi-stream/data_ID
-***** Use EJFAT LB firmware that supports load balancing of multiple source/data_IDs.
-***** EJFAT LB + RA engine performance as an event builder (i.e. source ID aggregator), a capability to send all available data_ID's with the same tick (time frame) to a single destination. NB Hall-B FT calorimeter and hodoscope setup is capable of sending up to 12 data streams.
