基于ubuntu22.04系统安装nvidia A100驱动与NVLink启用

1、官方仓库
针对驱动包下载认准nvidia官网
在这里插入图片描述

dpkg -i nvidia-driver-local-repo-ubuntu2204-550.54.15_1.0-1_amd64.deb
apt update
apt search nvidia-driver-550

2、安装
根据步骤1apt search nvidia-driver-550查出版本：此驱动包封在nvidia-driver-local-repo-ubuntu2204-550.54.15_1.0-1_amd64.deb中
apt install nvidia-driver-550
至此nvidia-smi PCIe通信方式已可用
nvidia-smi topo -m查看 GPU卡连接方式

3、启用NVLink高速模式
NVLink是GPU服务器厂家专为GPU间高效通信定制的连接，有硬件接口支持，比一般的PCIe速度快2倍以上。

apt install cuda-drivers-fabricmanager-550
apt install nvidia-modprobe

systemctl start nvidia-fabricmanager.service
systemctl status nvidia-fabricmanager.service 查看启动服务是否正常
nvidia-smi topo -m查看 GPU卡连接方式已变成NVLink

4、附：涉及的nvidia包
注意看版本比较统一：都是从本地仓库获取的550版本
