Install and configure CUDA in Ubuntu 14.04

Install and configure CUDA in Ubuntu 14.04

First, I installed Ubuntu 14.04.1.

1. Pre-Check

Check the system as shown in reference 1.

Run the following command:

:~ $ Lspci | grep-I nvidia
. 0 3D controller: NVIDIA Corporation GK110GL [Tesla K20c] (rev a1)
. 0 VGA compatible controller: NVIDIA Corporation gk0000gl [Quadro K4000] (rev a1)
. 1 Audio device: NVIDIA Corporation GK106 HDMI Audio Controller (rev a1)

Two GPUs, K20 and K4000, and an Audio, should be the sound card.

Then, run the command to check the system version:

~ $ 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"

We can see that the machine version is ubuntu14.04.

Then, use gcc -- version to check whether the gcc version meets the requirements in connection 1:

~ $ Gcc -- version
Gcc (Ubuntu 4.8.2-19ubuntu1) 4.8.2

After checking, go to the nvidia website (refer to link 3) to download the driver, which is the deb package of ubuntu14.04.

2. Installation
Deb package installation is relatively simple, but the installation process prompts instability, but there is nothing wrong with it.

Follow the instructions in link 2 to install the necessary libraries.

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

Or follow the process on the official website.

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

It may take a long time to download the file, but it doesn't matter.

If the installation is complete.

Prompt during installation:

* ** 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.

I'm not sure. I am prompted that the. run installation is relatively stable, but I am using it now.

3. Configure the environment

My system is 64-bit, so add it to. bashrc When configuring the environment

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

After the environment is configured, execute the command

~ $ Source. bashrc

Make it take effect immediately.

4. install sample

After the environment is configured, run the following command:

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

In this way, the cuda sample is copied to the dir folder. This command is only a copy operation.

Then enter the folder and execute the make command to compile. The compilation takes a long time and you need to wait.
