Multi-GPU Training

[lishuai-97]

Hello,

I have a question regarding multi-GPU training with the latest version of CityGS V2. When I used the scripts/run_citygs_mc_aerial.sh script to train the aerial view of MatrixCity, the training process only utilized a single GPU.

Could you please advise how to modify the training script or configuration to enable true multi-GPU training? Any guidance or recommendations for handling high-resolution training scenarios with multiple GPUs would be greatly appreciated.

Thank you very much for your time and support!
