Cuda

Installing Cuda

Note these instructions *only* apply to Fedora 16 and later releases.

To be reviewed, my english may be bad.

This document provides instructions to install Cuda 4.2 on Fedora. The final goal will be to be able to run GPUGRID applications.

Prerequisites

First, be sure your GPU is compatible with Cuda. Refer to this page: http://developer.nvidia.com/cuda-gpus. Then, install required packages:

su -c 'yum install make gcc-c++ freeglut-devel libXi-devel libXmu-devel mesa-libGLU-devel'

Downloads

You will have to download two programs: "CUDA Toolkit" and "GPU Computing SDK".

Let's download and save them on the Desktop.

32bits :

cd ~/Desktop
wget http://developer.download.nvidia.com/compute/cuda/4_2/rel/toolkit/cudatoolkit_4.2.9_linux_32_fedora14.run
wget http://developer.download.nvidia.com/compute/cuda/4_2/rel/sdk/gpucomputingsdk_4.2.9_linux.run

64bits :

cd ~/Desktop
wget http://developer.download.nvidia.com/compute/cuda/4_2/rel/toolkit/cudatoolkit_4.2.9_linux_64_fedora14.run
wget http://developer.download.nvidia.com/compute/cuda/4_2/rel/sdk/gpucomputingsdk_4.2.9_linux.run

Installation

CUDA Toolkit

Go to "Desktop", add execution permissions of the cudatoolkit downloaded file, and execute it with root permissions:

cd ~/Desktop
chmod +x cudatoolkit_4.2.9_linux_*
su -c './cudatoolkit_4.2.9_linux_*'

When it will ask you:

Enter install path (default /usr/local/cuda, '/cuda' will be appended):

type /opt.

GPU Computing SDK

As before, go to "Desktop", add execution permissions of the gpucomputingsdk downloaded file, and execute it without root permissions:

cd ~/Desktop
chmod +x gpucomputingsdk_4.2.9_linux.run
./gpucomputingsdk_4.2.9_linux.run

When it will ask you:

Enter install path (default ~/NVIDIA_GPU_Computing_SDK):

do [enter] (to use default path), and type /opt when it will ask you:

Enter CUDA install path (default /usr/local/cuda):

Preparation

Update variables, and this on every boot:

export PATH=$PATH:/opt/cuda/bin
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/opt/cuda/lib:/opt/cuda/lib64
echo 'export PATH=$PATH:/opt/cuda/bin' >> ~/.bash_profile
echo 'export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/opt/cuda/lib:/opt/cuda/lib64' >> ~/.bash_profile

Compilation

Fedora 16

We finally compile:

32bits:

cd ~/NVIDIA_GPU_Computing_SDK/C
LINKFLAGS=-L/usr/lib/nvidia/ make

64bits:

cd ~/NVIDIA_GPU_Computing_SDK/C
LINKFLAGS=-L/usr/lib64/nvidia/ make

Fedora 17

Will come soon...

Test

Now, let's test if Cuda is working great. Type:

~/NVIDIA_GPU_Computing_SDK/C/bin/linux/release/./fluidsGL

As you can see on the following picture, it works !

Now we can use GPUGRID applications with Boinc.
