I have two AMD Ryzen systems where both are with the Ryzen 9 5950X processor, but one as an Asus X570 TUF Gaming Pro WiFi motherboard whilst the other has an Asus ROG STRIX X570-E Gaming WiFi II motherboard.
Earlier today, I was trying to diagnose an issue with my 100 Gbps network connection between the two Ryzen nodes and the microcluster headnode, where upon running ib_send_bw, I was only getting around 14 Gbps.
Now that I took the discrete GPUs out from each of the systems, I’m getting 96.58 Gbps on my micro HPC cluster now.
Yay!!!
(I can’t imagine there being too many people who have Ryzen systems with 100 Gbps networking tying them together.)
