power delivery for 24/7 serving on B200

[batchwire]

This keeps coming up in conversation so I figured I'd start a thread.

The more I work with local setups, the more it seems like INT4 decides everything downstream.

Wondering if this is just where the whole space is heading now.

Good point. I don't think your conclusion is far off. The biggest change for me was simplifying the stack instead of adding one more optimization layer.

What worked for me was pretty simple. If you're on SGLang, I'd confirm the version first and then reduce variables until the behavior is obvious. Once you know the plain path works, then add the faster path back in piece by piece.

A couple questions before I guess too hard. Are you testing this on mini PC or something else?

Maybe, but I had the opposite result. I get why that seems right, but on 4090 the bottleneck felt elsewhere. Could be a workload difference, but I wouldn't generalize too fast from one setup.

There are a few different conversations hiding inside this thread, so being explicit about the goal helps.

A couple things I'd check first. Before rebuilding anything, I'd test one clean baseline with Gemma and compare from there.

following this because I'm in the same boat.
