How to check for GPU on CentOS Linux

Question

It is suggested that on Linux, GPU be found with the command lspci | grep VGA. It works fine on Ubuntu but when I try to use the same on CentOS, it says lspci comma

Answer 1

This assumes you have proprietary drivers installed, but issue the following command...

nvidia-smi

The output should look similar to this:

Answer 2

Try lshw or lspci. They have to be installed if you don't have already.

Install lshw

sudo yum install lshw //CentOS
sudo apt-get install lshw // Ubuntu

Then run this

sudo lshw -C display

The output would look like this

 *-display
       description: VGA compatible controller
       product: GP102 [GeForce GTX 1080 Ti]
       vendor: NVIDIA Corporation
       physical id: 0
       bus info: pci@0000:0b:00.0
       version: a1
       width: 64 bits
       clock: 33MHz
       capabilities: pm msi pciexpress vga_controller bus_master cap_list rom
       configuration: driver=nvidia latency=0
       resources: irq:95 memory:fb000000-fbffffff memory:e0000000-efffffff memory:de000000-dfffffff ioport:5000(size=128) memory:faf00000-faf7ffff

Similarly, you can try lspci

lspci | grep VGA

The output would look like this

0b:00.0 VGA compatible controller: NVIDIA Corporation GP102 [GeForce GTX 1080 Ti] (rev a1)

Answer 3

lspci should be in the package pciutils.

you could do this with dmidecode but as your not an admin you probably cant do this nor installing the pciutils package.

IF there is a Xorg on this system then it should be easy:

grep Graphics /var/log/Xorg.0.log

Answer 4

Well, if you use CUDA, it has a function to enumerate CUDA-capable devices on the system. Why not use that?

Answer 5

Have you tried to launch /sbin/lspci or /usr/sbin/lspci ?
