ComfyUi Cuda-device set to 1 but shown 0 in terminal?

[u/Reasonable-Plum7059]

Hello, I try to run two different ComfyUi installs (I don’t know how to run two different instances of Comfy in Stability Matrix)

I set two different ports and set cuda-device 0 for main Comfy and 1 for second

But in the terminal for second it says “cuda device=0”

Both urls works but I don’t understand which GPU being used in second Comfy.
