CentOS8下安装CUDA 10.2

第一步：先安装好nvidia驱动

第二步：打开终端，输入命令：nvcc --version，查看是否安装了cuda

运行命令：nvidia-smi

可以看到CUDA Version：10.2

第三步：入官网下载cuda10.2版本，按下面选好后，会给出安装命令

wget http://developer.download.nvidia.com/compute/cuda/10.2/Prod/local_installers/cuda-repo-rhel8-10-2-local-10.2.89-440.33.01-1.0-1.x86_64.rpm
sudo rpm -i cuda-repo-rhel8-10-2-local-10.2.89-440.33.01-1.0-1.x86_64.rpm
sudo dnf clean all
sudo dnf -y module install nvidia-driver:latest-dkms
sudo dnf -y install cuda

第四步：打开~/.bashrc，加入配置信息
[root@localhost ~]# vi ~/.bashrc

export PATH=/usr/local/cuda/bin:$PATH
export LD_LIBRARY_PATH=/usr/local/cuda/lib64:$LD_LIBRARY_PATH

更新~/.bashrc

[root@localhost ~]# source ~/.bashrc

重启后

第五步：确认CUDA正确安装，运行命令

$ nvcc --version
$ nvidia-smi

[root@localhost ~]# nvcc --version

第六步：测试CUDA程序

# mkdir cuda-samples

# cuda-install-samples-10.2.sh cuda-samples/

# cd ./cuda-samples/NVIDIA_CUDA-10.2_Samples/0_Simple/clock/

# make

[root@localhost ~]# mkdir cuda-samples
[root@localhost ~]# cuda-install-samples-10.2.sh cuda-samples/
Copying samples to cuda-samples/NVIDIA_CUDA-10.2_Samples now...
Finished copying samples.

[root@localhost ~]# cd ./cuda-samples/NVIDIA_CUDA-10.2_Samples/0_Simple/clock/
[root@localhost clock]# make
