generally lgtm. thanks!

does this mean vllm profiling works now? if so, could you add back those instructions into the nsys-profiling page? I had removed since it didn't work at the time

It doesn't work the same way as expected, the vllm worker still generate profiles because we still pass nsight kwargs to the VllmGenerationWorker, but those files have zero cuda events; meanwhile a new set of profiles named worker_process_%procid.nsys-rep are generated containing cuda events for vllm engine, we can't control the name or other nsight arguments as it is hardcoded in vllm here

Should we just remove the profiling wrapped around VllmGenerationWorker because that is basically an empty profile?

TODO i'll update the doc;

+1 to removing, if it's not giving anything

@terrykong I ended up keeping the original wrapper on VllmGeneration and the new one, because we need the previous one for Vllm's MP=1 case, and the new one for MP>1 case; I added an explanation about the generated files in the doc.

the DCO was broken by a previous commit brought in by merge; I had to force overwrite the branch but it's resolved now
