Were you able to connect the two P150 using the qsfp-dd cable? They only sell 4x and 8x topologies so I’m curious if that worked for you. Are you able to run them tensor parallel?

Yeah, I’m doing TP with two cards. The topology is configured based on yaml files, and if you are not using a predefined config you can just create a new config with your topology.

I’m not even using a 800G cable since they are expensive and I don’t think I need the bandwidth, opting for 400G instead. This just needs a config change for the number of Ethernet links it uses internally. (Apparently these cables are just many 200G links put together.)

Brilliant, thank you. Maybe I'll get a couple in a bit.
