CentOS 7 : installation of CUDA 6.5 to 8.0

The objective here is to propose a method of installation making it possible for several versions of CUDA to cohabit.

The installation described here was done the 10/20/2016 on a freshen udpate system by using :

sudo yum update && yum upgrade

We add the nvidia key and repository from www.elrepo.org:

sudo rpm --import https://www.elrepo.org/RPM-GPG-KEY-elrepo.org 
sudo rpm -Uvh http://www.elrepo.org/elrepo-release-7.0-2.el7.elrepo.noarch.rpm

Then we install nvidia-detect

sudo yum install nvidia-detect

When we run nvidia-detect, we obtain as result kmod-nvidia. So we install it

sudo yum install kmod-nvidia

The version of the installed driver is the 367.57-1. A reboot is needed to use the new driver.

For each CUDA version there is a minimal version of Nvidia driver for which CUDA functionality works



CUDA version	Driver version	download link



6.5	>= 340.00	cuda_6.5.14_linux_64.run

7.0	>= 346.00	cuda_7.0.28_with_346.75_linux.run

7.5	>= 352.00	cuda_7.5.18_linux.run

8.0	>= 361.00	cuda_8.0.44_linux-run

So we can download and install all these versions!

Before starting CUDA installation, we install the gcc, g++ and gfortran compiler

sudo yum install gcc gcc-c++ gcc-gfortran

The current version is the 4.8.5-4.

We also install some libraries to avoid some warning messages

sudo yum install mesa-libGLU-devel libXi-devel libXmu-devel

Otherwise, on my computer, I have these warning messages during the installation process:

Missing recommended library: libGLU.so Missing recommended library: libX11.so Missing recommended library: libXi.so Missing recommended library: libXmu.so

Due to an unsupported compiler (version 4.8.5), we use –override option for CUDA 6.5 installation.
