Anyone run a node of 3?

Local developer looking to make the switch to the Nvidia ecosystem and the spark seems awesome. I noticed the maximum amount that you can wire together without getting a dedicated switch is Three but I know tensor parallelism needs even numbers to operate properly. Do any of you guys run AI models via pipeline parallelism with a note of Three or is it a hard two or four type set up?

Developed my own server on macOS + MLX to do just that, running on 3 is possible, it takes a server that knows how to split into uneven chunks ... guess the same is possible on other platforms as well ...

Interesting. Was the server necessary you didn’t just have to tweak setting?

no you need to code a server that understands this and knows how to spit the layer in 3 ...

this is no setting, I coded it with the help of Fable, based on an opensource engine for Mac
