Unable to train the algorithms with 2 GPU instances (multi-node), each with 4 A100s

[CheruscanArminius]

The paper says the algorithm has been trained with 8 A100 GPUs.
I am having two instances, each equipped with 4 A100s instead of one GPU instance with 8 A100 GPUs.
Is there any way to specify the instances in the configurations? In another word, where can I specify the number of nodes in the code?

I would do appreciate if you could give a comment on these.

Update:

I added number of nodes to the training process and sent a pull request. In case of being accepted, this issue will be closed.
