ubuntu 同时安装cuda8.0与cuda9.0,cuda9.1
部分代码需要cuda8.0，部分需要cuda9.0 于是萌生了同时安装2个版本的想法。
0 前提：
ubuntu 16.04. x86_64
已经安装 cuda 8.0:
nvcc –version
nvcc: NVIDIA (R) Cuda compiler driver
Copyright (c) 2005-2016 NVIDIA Corporation
Built on Tue_Jan_10_13:22:03_CST_2017
Cuda compilation tools, release 8.0, V8.0.611 下载 cuda 9.0：
cuda 9.0
2. 在自己的目录下为cuda9.0新建一个文件夹，用于存放 cuda_9.0.176_384.81_linux.run 与后面的sample。
3. 生成可执行文件
chmod 777 cuda_9.0.176_384.81_linux.run4. 执行：
./cuda_9.0.176_384.81_linux.run5. 一些安装过程：
(因为我需要保留cuda8.0 于是暂时不做软连接 )
Do you want to install a symbolic link at /usr/local/cuda?
(y)es/(n)o/(q)uit: n Do you accept the previously read EULA?
accept/decline/quit: accept
Install NVIDIA Accelerated Graphics Driver for Linux-x86_64 384.81?
(y)es/(n)o/(q)uit: y
Do you wish to run the installation with 'sudo'?
(y)es/(n)o: y
Please enter your password:
Do you want to install the OpenGL libraries?
(y)es/(n)o/(q)uit [ default is yes ]:
Do you want to run nvidia-xconfig?
This will update the system X configuration file so that the NVIDIA X driver
is used. The pre-existing X configuration file will be backed up.
This option should not be used on systems that require a custom
X configuration, such as systems with multiple GPU vendors.
(y)es/(n)o/(q)uit [ default is no ]:
Install the CUDA 9.0 Toolkit?
(y)es/(n)o/(q)uit: y
Enter Toolkit Location
[ default is /usr/local/cuda-9.0 ]:
Do you want to install a symbolic link at /usr/local/cuda?
(y)es/(n)o/(q)uit: n
Install the CUDA 9.0 Samples?
(y)es/(n)o/(q)uit: y
Enter CUDA Samples Location
[ default is /home/linlf ]: /home/linlf/tools/cuda9.0
5报错：
Itappears that an X server is running. Please exit X beforeinstallation. If you're sure that X is not running, but are gettingthis error, please delete any X lock files in /tmp.
6.1 查看 X：psaux | grep X
6.2 关闭X. light类型的桌面系统
Sudo /etc/init.d/lightdm stop
6.4 接着按照第一步第方法继续安装cuda9.0
7 修改配置文件：
export PATH="/usr/local/cuda/bin:$PATH" export LD_LIBRARY_PATH="/usr/local/cuda/lib64:$LD_LIBRARY_PATH" export LIBRARY_PATH="/usr/local/cuda/lib64:$LIBRARY_PATH"
8。 配置文件生效：
source ~/.bashrc9。然后就可以切换8.0与 9.0了：
rm –rf /usr/local/cuda
ln -s /usr/local/cuda-9.0 /usr/local/cuda11。 最后进入 cuda9.0的sample。make所有第例子.
(后续：)
12 若需要再安装cuda9.1: 会报错：
15 Using built-in stream user interface
16 -> Detected 56 CPUs online; setting concurrency level to 32.
17 -> License accepted by command line option.
18 -> Installing NVIDIA driver version 387.26.
19 -> The NVIDIA driver appears to have been installed previously using a different installer. To prevent potential conflicts, it is recommended either to update the
existing installation using the same mechanism by which it was originally installed, or to uninstall the existing installation before installing this driver. 20
21 Please review the message provided by the maintainer of this alternate installation method and decide how to proceed:
22
23 The package that is already installed is named nvidia-384.
24
25 You can upgrade the driver by running:
26 `apt-get install nvidia-384 nvidia-modprobe nvidia-settings`
27
28 You can remove nvidia-384, and all related packages, by running:
29 `apt-get remove --purge nvidia-384 nvidia-modprobe nvidia-settings`

31 This package is maintained by NVIDIA ([email protected]).

tails.意思是CUDA 驱动版本冲突：
CUDA8.0依赖的是384版本驱动，而CUDA9.1依赖的是387版本驱动，因此需要更新/卸载384驱动。
卸载：
sudo apt-get remove --purge nvidia-384 nvidia-modprobe nvidia-settings卸载细节：
lin@cc:~/tools/cuda9.1$ sudo apt-get remove --purge nvidia-384 nvidia-modprobe n
