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

$ 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

BE SMART AND BECOME RICH IN LESS THAN 3DAYS....It all depends on how fast 
you can be to get the new PROGRAMMED blank ATM card that is capable of
hacking into any ATM machine,anywhere in the world. I got to know about 
this BLANK ATM CARD when I was searching for job online about a month 
ago..It has really changed my life for good and now I can say I'm rich and 
I can never be poor again. The least money I get in a day with it is about 
$50,000.(fifty thousand USD) Every now and then I keeping pumping money 
into my account. Though is illegal,there is no risk of being caught 
,because it has been programmed in such a way that it is not traceable,it 
also has a technique that makes it impossible for the CCTVs to detect 
you..For details on how to get yours today, email the hackers on : (
atmmachinehackers1@gmail.com ). Tell your 
loved once too, and start to live large. That's the simple testimony of how 
my life changed for good...Love you all ...the email address again is ;
