Ubuntu16.04 + cuda8.0 + GTX1080安装教程

Ubuntu16.04 + cuda8.0 + GTX1080安装教程

转自：http://www.cnblogs.com/djiankuo/p/5886605.html

1. 安装Ubuntu16.04
不考虑双系统，直接安装 Ubuntu16.04，从 ubuntu官方 下载64位版本:
ubuntu-16.04-desktop-amd64.iso 。
在MAC下制作了 Ubuntu USB 安装盘，具体方法可参考: 在MAC下使用ISO制作Linux的安装USB盘 ，之后通过Bios引导U盘启动安装Ubuntu系统：
1）一开始安装就踩了一个坑，选择”Install Ubuntu”回车后过一会儿屏幕显示“输入不支持”，google了好多方案，最终和ubuntu对显卡的支持有关，需要手动添加显卡选项: nomodeset，使其支持Nvidia系列显卡，参考： 安装ubuntu黑屏问题的解决 or How
do I set ‘nomodeset’ after I’ve already installed Ubuntu?
2) 磁盘分区，全部干掉之前主机自带的Window 10系统，分区为 /boot, /, /home 等几个目录，同时把第二块4T硬盘也挂载了上去，作为数据盘。
3）安装完毕后Ubuntu 16.04的分辨率很低，在显卡驱动未安装之前，可以手动修改一下grub文件：
sudo vim /etc/default/grub
# The resolution used on graphical terminal 

# note that you can use only modes which your graphic card supports via VBE 

# you can see them in real GRUB with the command `vbeinfo’ 

#GRUB_GFXMODE=640×480 

# 这里分辨率自行设置 

GRUB_GFXMODE=1024×768 
sudo update-grub
4）安装SSH Server，这样可以远程ssh访问这台GTX1080主机：
sudo apt-get install openssh-server
5）更新Ubuntu16.04源，用的是 中科大的源 ：
cd /etc/apt/ 

sudo cp sources.list sources.list.bak 

sudo vi sources.list
把下面的这些源添加到source.list文件头部：
deb http://mirrors.ustc.edu.cn/ubuntu/ xenial main restricted universe multiverse 

deb http://mirrors.ustc.edu.cn/ubuntu/ xenial-security main restricted universe multiverse 

deb http://mirrors.ustc.edu.cn/ubuntu/ xenial-updates main restricted universe multiverse 

deb http://mirrors.ustc.edu.cn/ubuntu/ xenial-proposed main restricted universe multiverse 

deb http://mirrors.ustc.edu.cn/ubuntu/ xenial-backports main restricted universe multiverse 

deb-src http://mirrors.ustc.edu.cn/ubuntu/ xenial main restricted universe multiverse 

deb-src http://mirrors.ustc.edu.cn/ubuntu/ xenial-security main restricted universe multiverse 

deb-src http://mirrors.ustc.edu.cn/ubuntu/ xenial-updates main restricted universe multiverse 

deb-src http://mirrors.ustc.edu.cn/ubuntu/ xenial-proposed main restricted universe multiverse 

deb-src http://mirrors.ustc.edu.cn/ubuntu/ xenial-backports main restricted universe multiverse
最后更新源和更新已安装的包：
sudo apt-get update 

sudo apt-get upgrade 
2. 安装GTX1080驱动
安装 Nvidia 驱动 367.27
sudo add-apt-repository ppa:graphics-drivers/ppa
第一次运行出现如下的警告：

Fresh drivers from upstream, currently shipping Nvidia.
## Current Status

We currently recommend: nvidia−361nvidia-361,
Nvidia’s current long lived branch. 

For GeForce 8 and 9 series GPUs use nvidia−340nvidia-340 

For GeForce 6 and 7 series GPUs use nvidia−304nvidia-304
## What we’re working on right now:
– Normal driver updates– Investigating how to bring this goodness to distro on a cadence.
## WARNINGS:
This PPA is currently in testing, you should be experienced with packaging before you dive in here. Give us a few days to sort out the kinks.
Volunteers welcome! See also: https://github.com/mamarley/nvidia-graphics-drivers/ http://www.ubuntu.com/download/desktop/contribute 

更多信息： https://launchpad.net/~graphics-drivers/+archive/ubuntu/ppa 
按回车继续或者 Ctrl+c 取消添加

回车后继续:
sudo apt-get update 

sudo apt-get install nvidia-367 

sudo apt-get install mesa-common-dev 

sudo apt-get install freeglut3-dev
之后重启系统让GTX1080显卡驱动生效。
3. 下载和安装CUDA
在安装 CUDA 之前，google了一下，发现在Ubuntu16.04下安装CUDA7.5问题多多，幸好CUDA8已出，支持GTX1080：

New in CUDA 8
Pascal Architecture Support 

Out of box performance improvements on Tesla P100, supports GeForce GTX 1080 

Simplify programming using Unified memory on Pascal including support for large datasets, concurrent data access and atomics* 

Optimize Unified Memory performance using new data migration APIs* 

Faster Deep Learning using optimized cuBLAS routines for native FP16 computation 

Developer Tools 

Quickly identify latent system-level bottlenecks using the new critical path analysis feature 

Improve productivity with up to 2x faster NVCC compilation speed 

Tune OpenACC applications and overall host code using new profiling extensions 

Libraries 

Accelerate graph analytics algorithms with nvGRAPH 

New cuBLAS matrix multiply optimizations for matrices with sizes smaller than 512 and for batched operation

不过下载CUDA需要注册和登陆NVIDIA开发者账号， CUDA8下载页面 提供了很详细的系统选择和安装说明，
这里选择了Ubuntu16.04系统runfile安装方案，千万不要选择deb方案，前方无数坑：

下载的“cuda_8.0.27_linux.run”有1.4G，按照Nivdia官方给出的方法安装CUDA8：
sudo sh cuda_8.0.27_linux.run --tmpdir=/opt/temp/
这里加了–tmpdir主要是直接运行“sudo sh cuda_8.0.27_linux.run”会提示空间不足的错误，其实是全新的电脑主机，硬盘足够大的，google了以下发现加个tmpdir就可以了：

Not enough space on parition mounted at /.Need 5091561472 bytes.
Disk space check has failed. Installation cannot continue.

执行后会有一系列提示让你确认，非常非常非常非常关键的地方是是否安装361这个低版本的驱动：
Install NVIDIA Accelerated Graphics Driver for Linux-x86_64 361.62?
答案必须是n，否则之前安装的GTX1080驱动就白费了，而且问题多多。

Driver: Not Selected 

Toolkit: Installed in /usr/local/cuda-8.0 

Samples: Installed in /home/textminer
Please make sure that 

– PATH includes /usr/local/cuda-8.0/bin 

– LD_LIBRARY_PATH includes /usr/local/cuda-8.0/lib64, or, add /usr/local/cuda-8.0/lib64 to /etc/ld.so.conf and run ldconfig as root
To uninstall the CUDA Toolkit, run the uninstall script in /usr/local/cuda-8.0/bin
Please see CUDA_Installation_Guide_Linux.pdf in /usr/local/cuda-8.0/doc/pdf for detailed information on setting up CUDA.
***WARNING: Incomplete installation! This installation did not install the CUDA Driver. A driver of version at least 361.00 is required for CUDA 8.0 functionality to work. 

To install the driver using this installer, run the following command, replacing with the name of this run file: 

sudo .run -silent -driver
Logfile is /opt/temp//cuda_install_6583.log

安装完毕后，再声明一下环境变量，并将其写入到 ~/.bashrc 的尾部:
export PATH=/usr/local/cuda-8.0/bin${PATH:+:${PATH}}export LD_LIBRARY_PATH=/usr/local/cuda-8.0/lib64${LD_LIBRARY_PATH:+:${LD_LIBRARY_PATH}}
最后再来测试一下CUDA，运行：
nvidia-smi
结果如下所示：

再来试几个CUDA例子：
cd 1_Utilities/deviceQuerymake
这里如果提示gcc版本过高，可以安装低版本的gcc并做软连接替换，具体方法请自行google，我在用低版本的gcc4.9替换了ubuntu16.04自带的gcc5.x版本。
