I got a new pc, and am having troubles getting my extra graphics cards to be detected by PyTorch and nvidia-smi. I’ve looked around and can’t find articles with the same issue
I’m using Ubuntu 22.04
I have a 4060 ti and two Quadro GP100s connected by a NVLink bridge
nvidia-smi detects my 4060 just fine and it outputs graphics, but not the quadros. lspci detects one quadro though, so they seem to be registered by the system. However, I can’t get any graphics output from them.
The nvidia driver installed is 560.35.03, which Nvidia says supports the GP100s.
I found this saying the GP100 is certified for Ubuntu 20.04, but could not find a similar page for 22.04. Do I need to switch to 20.04 to use my GP100s?
Does anyone know how to fix this? Is this somehow due to the NVlink bridge? Is there other software I need to install?
I set up my drivers automatically with
sudo ubuntu-drivers install
and I installed the cuda toolkit with
sudo apt install nvidia-cuda-toolkit
Below is the output of lspci | grep VGA
01:00.0 VGA compatible controller: NVIDIA Corporation Device 2803 (rev a1)
16:00.0 VGA compatible controller: NVIDIA Corporation GP100GL [Quadro GP100] (rev a1)
17:00.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] Device 164e (rev c9)
Could there be an issue since only one Quadro is detected by lspci?
Below is the output of nvidia-smi
