How to check for GPU on CentOS Linux
提问by pythonic
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 command is not found. How can I check for the GPU card on CentOS. And note that I'm not the administrator of the machine and I only use it remotely from command line. I intend to use the GPU as a GPGPU on that machine, but first I need to check if it even has one.
建议在 Linux 上使用命令找到 GPU lspci | grep VGA。它在 Ubuntu 上运行良好，但是当我尝试在 CentOS 上使用它时，它说找不到 lspci 命令。如何在 CentOS 上检查 GPU 卡。请注意，我不是机器的管理员，我只能从命令行远程使用它。我打算将 GPU 用作那台机器上的 GPGPU，但首先我需要检查它是否有。

Have you tried to launch /sbin/lspcior /usr/sbin/lspci?
您是否尝试启动/sbin/lspci或/usr/sbin/lspci？

lspci should be in the package pciutils.
lspci 应该在 pciutils 包中。
you could do this with dmidecode but as your not an admin you probably cant do this nor installing the pciutils package.
您可以使用 dmidecode 执行此操作，但由于您不是管理员，因此您可能无法执行此操作，也无法安装 pciutils 包。
IF there is a Xorg on this system then it should be easy:
如果这个系统上有一个 Xorg 那么它应该很容易：
grep Graphics /var/log/Xorg.0.log

Well, if you use CUDA, it has a function to enumerate CUDA-capable devices on the system. Why not use that?
好吧，如果您使用 CUDA，它具有枚举系统上支持 CUDA 的设备的功能。为什么不使用它？

This assumes you have proprietary drivers installed, but issue the following command...
这假设您安装了专有驱动程序，但发出以下命令...
nvidia-smi
The output should look similar to this:
输出应该类似于：

Try lshwor lspci. They have to be installed if you don't have already.
尝试lshw或lspci。如果您还没有安装它们，则必须安装它们。
Install lshw
安装 lshw
sudo yum install lshw //CentOS
sudo apt-get install lshw // Ubuntu
Then run this
然后运行这个
sudo lshw -C display
The output would look like this
输出看起来像这样
