Adding a second GPU
 

I'm planning on adding a second Quadro GPU to my system and am doing some prep. I'm currently running Arch Linux. The GPUs will be identical. I'm also using the latest NVIDIA driver. I'm currently using the GPUs to support my deep learning work.

I read the Arch Wiki entry at https://wiki.archlinux.org/index.php...s#Enabling_SLI. Thing is that I don't really need SLI to support PyTorch. I'm just leveraging CUDA. That being the case is it just as simple as installing the second Quadro and booting up?


Edit:
Looks like I may also have to update xorg.conf. I suppose that after installing the second gpu I could boot in run level three and use nvidia-settings to update the file.

I'd recommend writing an /etc/X11/xorg.conf.d/nn-video.conf using the info in the Video section of 'man xorg.conf.' Particularly important would be the ServerLayout section.
