Yes, Leela supports multiple GPUs. You just pass multiple

Code: Select all

--gpu <OpenCL ID>
parameters to the engine.

I've tested that this works on 8 K80s (although I didn't have enough CPU to fully utilize all those GPUs, at 1 thread per GPU NPS scaled linearly; I just couldn't drive GPU utilization much past 50% when using all 8), so as long as you have <= 8 GPUs, you're in tested territory :)
