Description
Currently, when I run Flux on a device with a single L40 GPU, I encounter an OutOfMemory error. I found another device L40 with two GPUs. How can I implement multi-GPU usage to run flux?

Research direction
Begin with the flux-demo reproduction on TensorRT 10.5 using one L40 GPU and the reported OutOfMemory failure, then compare it with the two-L40 setup. Done means establishing whether the demo can use both GPUs and documenting or implementing a confirmed way to run it without the reported failure.
