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/remove Cuda 4.2 on Fedora. The final goal will be to be able to run GPUGRID applications.

Installation

Prerequisites

First, be sure your GPU is compatible with Cuda. Refer to this page. Then, install required packages:

su -c 'yum install wget 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". Refer to the NVidia CUDA downloads page for latest versions.

Let's download and save them on the Desktop.

32 bit :

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

64 bit :

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 of 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 asks you:

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

type:

/opt

Installation of 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):

press [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

Some compatibility problems appeared with gcc-4.7. You will have to install a compatibility version:

su -c 'yum install compat-gcc-34 compat-gcc-34-c++'

Create a symbolic link to make Cuda point to gcc-3.4:

su -c 'ln -s /usr/bin/gcc34 /opt/cuda/bin/gcc'

Now, you can compile.

32bits:

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

64bits:

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

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.

Cleanup

Now Cuda is installed, the installers files are useless, you can remove them:

cd ~/Desktop
rm cudatoolkit_4.2.9_linux_*
rm gpucomputingsdk_4.2.9_linux.run

Uninstallation

If you want to totally remove Cuda, juste delete the /opt/cuda and ~/NVIDIA_GPU_Computing_SDK folders:

rm -r ~/NVIDIA_GPU_Computing_SDK
su -c 'rm -r /opt/cuda'

and remove the export PATH=$PATH:/opt/cuda/bin and export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/opt/cuda/lib:/opt/cuda/lib64 lines of the ~/.bash_profile file.
