OS：ubuntu 14.04

GPU：GTX 960

之前ubuntu已经安装了cuda7.5，本次通过deb升级到cuda8.0，参考了nvidia的英文安装指导，本人是第一次写博客，只是把自己操作的步骤写下来，有些地方可能有问题，请及时指正，谢谢！

升级之前的准备工作

1  uname -m && cat /etc/\*release   \# get ubuntu version  
2  uname -r                                          \# get ubuntu kernal version

3   gcc --version                                    \# get gcc version  
4  lspci | grep -i nvidia                        \# check nvidia GPU information  
5  cat /proc/driver/nvidia/version        \# check nvidia GPU driver version

开始升级cuda8.0

1    download **7fa2af80.pub** file from[http://developer.download.nvidia.com/compute/cuda/repos/ubuntu1404/x86\_64/7fa2af80.pub][http_developer.download.nvidia.com_compute_cuda_repos_ubuntu1404_x86_64_7fa2af80.pub]  
2    cat 7fa2af80.pub | apt-key add -  
3    download cuda-repo-ubuntu1404\_8.0.44-1\_amd64.deb from[http://developer.download.nvidia.com/compute/cuda/repos/ubuntu1404/x86\_64/cuda-repo-ubuntu1404\_8.0.44-1\_amd64.deb][http_developer.download.nvidia.com_compute_cuda_repos_ubuntu1404_x86_64_cuda-repo-ubuntu1404_8.0.44-1_amd64.deb]

4    ms5sum cuda-repo-ubuntu1404\_8.0.44-1\_ amd64.deb    \#check download file if available  
5    sudo dpkg -i cuda-repo-ubuntu1404\_8.0.44-1\_ amd64.deb  
6    sudo apt-get update  
7    sudo apt-get install cuda  
8    sudo vi ~/.bashrc       \# add PATh and LD\_LIBRARY\_PATH at the end  
      export PATH=/usr/local/cuda-8.0/bin:$ PATH  
      export LD\_LIBRARY\_PATH=/usr/local/ cuda-8.0/lib64:$LD\_LIBRARY\_ PATH  
9    Source ~/.bashrc  
10  sudo reboot  
11  dpkg -l | grep nvidia    \# view all nvidia driver  
12  nvidia-smi                      \#check GPU memory information       
13  cd  /usr/local/cuda-8.0/samples  
14  make                                \# compile cuda-8.0 sample files  
15  cd bin/x86\_64/linux/release/    \# run sample file  
16  ./deviceQuery  
17  ./bandwidthTest

我在安装完cuda8.0后没有重启ubuntu，运行sample的时候出现错误，could not insert 'nvidia\_361\_uvm':Invalid argument，检查nvidia driver version还是352.79，没有升级到361.93，而且运行nvidia-smi出现Failed to initialize NVML: Driver/library version mismatch，尝试重新安装361驱动，并sudo apt-get upgrade，然后重启ubuntu后，发现驱动升级到361.93了，运行nvidia-smi也显示正确GPU信息了。重新make sample file，在release目录下运行sample文件deviceQuery运行正常，返回正确值，passed
