Questions about running Carla on GPU servers

[YilinGao-SHU]

Thanks so much for your work! But I got some puzzle problems when I try to run Carla on a GPU Server with 8 GPUs, when I use the following commands to start a Carla server, all the process run on gpu 0 like this.
CUDA_VISIBLE_DEVICES=0 ./CarlaUE4.sh --world-port=20000 -carla-server & CUDA_VISIBLE_DEVICES=1 ./CarlaUE4.sh --world-port=20002 -carla-server &
Have u ever met this mistake?

Hi!
Could you show the output of nvidia-smi? I can not understand the screenshot :)

Of course! The usage of the GPUs looks like this. It can be found that all Carla process run on GPU 0.

Looking forward to your reply~

Hi, this is my nvidia-smi output and it looks ok:

the corresponginf script:

CUDA_VISIBLE_DEVICES=0 ./CarlaUE4.sh --world-port=2000 -opengl  &
sleep 1
CUDA_VISIBLE_DEVICES=1 ./CarlaUE4.sh --world-port=2002 -opengl  &
sleep 1
CUDA_VISIBLE_DEVICES=2 ./CarlaUE4.sh --world-port=2004 -opengl  &
sleep 1
CUDA_VISIBLE_DEVICES=3 ./CarlaUE4.sh --world-port=2006 -opengl  &
sleep 1
