Possible to utilize multiple GPUs at once?

[eraser851]

Is it possible to utilize the VRAM from multiple GPUs at once, rather than selecting which to use individually?

Recently added a 2nd GPU and (48GB total) and keep getting out of memory errors (where the model worked fine on the single card).

I only have one GPU, so I am not able to test for or support multiple GPUs.
