NVIDIA GPU 开启 Persistent Mode

以下为利用GPU驱动自带工具配置GPU驱动内存常驻模式开机自启动，该脚本需要系统下预安装sed、useradd、userdel、id命令，否则会执行失败。

cd /usr/share/doc/NVIDIA_GLX-1.0/samples/
ls
#nvidia-persistenced-init.tar.bz2  systemd
tar xvf nvidia-persistenced-init.tar.bz2 
ls
#nvidia-persistenced-init  nvidia-persistenced-init.tar.bz2  systemd
cd nvidia-persistenced-init/
./install.sh

#以上表示脚本配置成功

#通过以下命令检查服务状态是否正常,并执行nvidia-smi确认Persistence-M状态为on
systemctl status nvidia-persistenced.service
#配置完成后重启OS验证systemctl status nvidia-persistenced.service是否正常启动
