如何在CentOS Linux上检查GPU

Question

建议在Linux上使用该命令找到GPU lspci | grep VGA.它在Ubuntu上运行正常但是当我尝试在CentOS上使用它时,它说没有找到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.我打算在那台机器上使用GPU作为GPGPU,但首先我需要检查它是否有一台.

Answer 1

这假设您已安装专有驱动程序,但发出以下命令...

nvidia-smi

输出应该类似于:

Answer 2

你试过推出/sbin/lspci还是/usr/sbin/lspci？

Answer 3

尝试lshw或lspci。如果您还没有安装它们，则必须安装它们。

安装 lshw

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

然后运行这个

sudo lshw -C display

输出看起来像这样

 *-display

       vendor: NVIDIA Corporation
       physical id: 0

       version: a1

       clock: 33MHz

同样，您可以尝试 lspci

lspci | grep VGA

输出看起来像这样
