- Spare EJFAT equip loaners:
- Next Steps:
- EJFAT VLAN Checkout
- Network Performance:
- FPGA LB Throughput - max sustained 90Gbs
- 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
- Pktgen-DPDK
- Look at ROCE / NIC
- 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)
