Ubuntu 14.04安装配置CUDA

发布时间:2014-10-14 09:49:18来源:linux网站作者:stdcoutzyx

首先,我装的系统是Ubuntu 14.04.1。


1. 预检查

按照参考链接1中所示,检查系统。

执行命令:

:~$ lspci | grep -i nvidia
03:00.0 3D controller: NVIDIA Corporation GK110GL [Tesla K20c] (rev a1)
04:00.0 VGA compatible controller: NVIDIA Corporation GK106GL [Quadro K4000] (rev a1)
04:00.1 Audio device: NVIDIA Corporation GK106 HDMI Audio Controller (rev a1)

发现有K20和K4000两块GPU,还有一块Audio的应该是声卡。

然后,执行命令检查系统版本:

~$ uname -m && cat /etc/*release
x86_64
DISTRIB_ID=Ubuntu
DISTRIB_RELEASE=14.04
DISTRIB_CODENAME=trusty
DISTRIB_DESCRIPTION="Ubuntu 14.04.1 LTS"
NAME="Ubuntu"
VERSION="14.04.1 LTS, Trusty Tahr"
ID=ubuntu
ID_LIKE=debian
PRETTY_NAME="Ubuntu 14.04.1 LTS"
VERSION_ID="14.04"
HOME_URL="http://www.ubuntu.com/"
SUPPORT_URL="http://help.ubuntu.com/"
BUG_REPORT_URL="http://bugs.launchpad.net/ubuntu/"

可以看到,机器是ubuntu14.04的版本。

然后,使用gcc --version检查gcc版本是否符合链接1中的要求:

~$ gcc --version
gcc (Ubuntu 4.8.2-19ubuntu1) 4.8.2
Copyright (C) 2013 Free Software Foundation, Inc.
This is free software; see the source for copying conditions.  There is NO
warranty; not even for MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

检查完毕,就去nvidia的官网(参考链接3)上下载驱动,为下载的是ubuntu14.04的deb包。


2. 安装
Deb包安装较为简单,但是安装过程中提示不稳定,不过用着也没啥出错的地方。

先按照参考链接2安装必要的库。

sudo apt-get install freeglut3-dev build-essential libx11-dev libxmu-dev libxi-dev libgl1-mesa-glx libglu1-mesa libglu1-mesa-dev

还是按照官网上的流程来。

$ sudo dpkg -i cuda-repo-<distro>_<version>_<architecture>.deb
$ sudo apt-get update
$ sudo apt-get install cuda

可能需要下载较长时间,但是没关系,放在那等着就是。

没啥问题就算安装好了。

安装过程中提示:

*** Please reboot your computer and verify that the nvidia graphics driver is loaded. ***
*** If the driver fails to load, please use the NVIDIA graphics driver .run installer ***
*** to get into a stable state.

我没管,提示使用.run安装比较稳定,但我现在用着没问题。


3. 配置环境

我的系统是64位的,因此配置环境时在.bashrc中加入

$ export PATH=/usr/local/cuda-6.5/bin:$PATH
$ export LD_LIBRARY_PATH=/usr/local/cuda-6.5/lib64:$LD_LIBRARY_PATH

配置完环境后,执行命令

~$ source .bashrc

使其立刻生效。


4. 安装sample

配置好环境后,可以执行如下命令:

$ cuda-install-samples-6.5.sh <dir>

这样,就将cuda的sample拷贝到dir文件夹下了。该命令只是一个拷贝操作。

然后进入该文件夹,执行make命令进行编译,编译时间较长,需要等待。


5. 验证安装是否成功

5.1. 驱动验证

首先,验证nvidia的驱动是否安装成功。

~$ cat /proc/driver/nvidia/version
NVRM version: NVIDIA UNIX x86_64 Kernel Module  340.29  Thu Jul 31 20:23:19 PDT 2014
GCC version:  gcc version 4.8.2 (Ubuntu 4.8.2-19ubuntu1)

5.2. Toolkit验证

验证cuda toolkit是否成功。

~$ nvcc -V
nvcc: NVIDIA (R) Cuda compiler driver
Copyright (c) 2005-2014 NVIDIA Corporation
Built on Thu_Jul_17_21:41:27_CDT_2014
Cuda compilation tools, release 6.5, V6.5.12

5.3. 设备识别

使用cuda sample已经编译好的deviceQuery来验证。deviceQuery在<cuda_sample_install_path>/bin/x_86_64/linux/release目录下。我的结果如下,检测出了两块GPU来。

~/install/NVIDIA_CUDA-6.5_Samples/bin/x86_64/linux/release$ ./deviceQuery
