host memory: RoCEv2 w1 <-> w2 <-> w3 <-> w4 <-> w5 <-> w1: 10125 MB/s
- move network controller to appropriate PCIe position
- enable RoCEv2 (priority flow control, etc.) on switch
- e.g. on Dell switch we used, see https://www.dell.com/support/manuals/en-us/dell-emc-smartfabric-os10/smartfabric-os-user-guide-10-5-2-6/configure-roce-on-the-switch?guid=guid-ddfa4455-8f64-4014-8543-ceb6719c904d&lang=en-us

GPU RDMA: pursai-9654 <-> gpu8
Notice, this may require PCIe switch & professional GPU for NVIDIA. Not sure situation for AMD GPU.
1. ROCm Platform
1. Check Firmware Setup
Enable PCIe resizable bar & tune MMIO address setup, refer to: https://github.com/openucx/ucx/wiki/Build-and-run-ROCM-UCX-OpenMPI
Bar address of GPUs should be < 44 bits for gfx900 / gfx906 devices, otherwise segmentation fault will still happen.
2. run the test
/opt/ucx/bin/ucx_perftest -c 0
/opt/ucx/bin/ucx_perftest -t ucp_get 10.0.1.2 -s 1073741824 -c 3 -w 3 -n 10000 -m rocm

2. CUDA Platform
1. Check if nvidia_peermem is correctly loaded
sudo modprobe nvidia_peermem
sometimes it gives symbol mismatch in dmesg:
[31832.683273] nvidia_peermem: disagrees about version of symbol ib_register_peer_memory_client
[31832.683276] nvidia_peermem: Unknown symbol ib_register_peer_memory_client (err -22)
this is possibly caused by installing Mellanox OFED driver after installing NVIDIA driver, and NVIDIA driver is using ib_* in kernel. Just rebuild NVIDIA driver:
sudo dkms status
sudo dkms unbuild nvidia/...
sudo dkms build nvidia/...
2. run the test
/opt/ucx/bin/ucx_perftest -c 0
/opt/ucx/bin/ucx_perftest -t ucp_put_bw 10.0.1.2 -s 1073741824 -c 3 -w 3 -n 10000 -m cuda
