How to detect if computer supports CUDA?

To run applications that use CUDA we need to make sure that our computer has GPUs that support CUDA.

From Google Chrome Browser

Go to

chrome://gpu/

and in the result page look for:

GPU CUDA compute capability major version

It is also possible to check here the presence of GPUs on the system:

Driver Information

...

GPU0 VENDOR= 0x10de, DEVICE=0x13b4

GPU1 VENDOR= 0x8086, DEVICE=0x591b *ACTIVE*

...

0x10DE is NVIDIA's vendor ID.

0x8086 is Intel's vendor ID.

Check Graphic Cards

GPUs on NVIDA graphic cards support CUDA co check if you have any of them on your board:

$ lspci

...

01:00.0 VGA compatible controller: NVIDIA Corporation GK107 [GeForce GT 640 OEM] (rev a1)

...

Run nvidia-settings

nvidia-settings can be installed with:

$ sudo apt install nvidia-settings

$ nvidia-settings

Run nvidia-smi

nvidia-smi can be installed with:

sudo apt install nvidia-340 # version 340.108-0ubuntu5.20.04.1, or

sudo apt install nvidia-utils-390 # version 390.141-0ubuntu0.20.04.1

sudo apt install nvidia-utils-450 # version 450.102.04-0ubuntu0.20.04.1

sudo apt install nvidia-utils-450-server # version 450.102.04-0ubuntu0.20.04.1

sudo apt install nvidia-utils-460 # version 460.32.03-0ubuntu0.20.04.1

sudo apt install nvidia-utils-435 # version 435.21-0ubuntu7

sudo apt install nvidia-utils-440 # version 440.82+really.440.64-0ubuntu6

sudo apt install nvidia-utils-418-server # version 418.181.07-0ubuntu0.20.04.1

$ sudo apt install nvidia-utils-460

$ nvidia-smi

NVIDIA-SMI has failed because it couldn't communicate with the NVIDIA driver. Make sure that the latest NVIDIA driver is installed and running.

https://www.nvidia.com/en-us/drivers/unix/

https://www.nvidia.com/Download/driverResults.aspx/170134/en-us contains download section with a link to file NVIDIA-Linux-x86_64-460.39.run (so the latest version is 460) but it also contains this note:

Note that many Linux distributions provide their own packages of the NVIDIA Linux Graphics Driver in the distribution's native package management format. This may interact better with the rest of your distribution's framework, and you may want to use this rather than NVIDIA's official package.

So let's check what apt contains:

$ apt search nvidia-driver
