Agenda:
- Previous meeting
- Status:
- Using ESnet FPGA f/w build 28 April
- Specs
- Jumbo Frames
- arp, ping, ICMP filtering
- Port entropy
- Script based LB Control Plane
- Support C libraries for LB Host Control Plane - in
unit testcode reviewlegal review - ESnet smartnic open-source GitHub repo - in legal review
- ESnet private, forkable Jlab P4 and simulations GitHub repo - in legal review
- ERSAP feed end bottleneck needs investigation; Timmer's blaster may provide relief
- New machines (6) rec'd, installed w/ Ubuntu 20.04 on EJFAT subnet (VLAN 937 172.19.22.0/24)
- 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

- (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 (6) 100Gbs NICs - ETA 1 July
- PR408870 PR408938 (2) 100Gbs Arista switches,
transceivers, cables, etc - ETA1 July5 October
- (4) DAQ dev machines indra-s[1-3] 129.57.29/109.23[0-2]
- Using ESnet FPGA f/w build 28 April
- Next Steps:
- EJFAT VLAN Checkout
- Network Performance:
- FPGA LB Throuput - max sustained 90Gbs
- Host NICs
- Host S/W Reassembly - better algorithms, buffering, asynchronicity, etc.
- EJFAT UDP Transmission Performance
- Need better parameters for event reassembly/reconstruction
- Control Plane
- Will interact with SLURM / Kubernetes
- Python based (?)
- Control Plane daemon for compute host (?)
- Demonstrate CP based flexibility/elasticity
- Look at iperf2 for network testing
- Look at ROCE / NIC
- DPDK - ESnet reports can stream 100 Gbps using DPDK.
- SLURM env for EJFAT VLAN (Hess)
- DAQ/VTP Data Generation Test Harness
