NVIDIA CUDA Installation

This Howto provides a way to install the official NVIDIA packages for CUDA.

NVIDIA CUDA Repository

This repository contains a given version of CUDA that is parallel installable along with another version.

Please use the Official link: https://developer.nvidia.com/cuda-downloads

* RHEL/CentOS 7

sudo yum install http://developer.download.nvidia.com/compute/cuda/repos/rhel7/x86_64/cuda-repo-rhel7-8.0.44-1.x86_64.rpm
sudo yum install cuda

* Fedora 23 (and later)

sudo dnf install http://developer.download.nvidia.com/compute/cuda/repos/fedora23/x86_64/cuda-repo-fedora23-8.0.44-1.x86_64.rpm
sudo dnf install cuda

GCC version issue

When using a later version of Fedora than what is supported by the NVIDIA CUDA Official repository, you might be unable to compile. You can either: * Tweak the /usr/local/cuda-8.0/targets/x86_64-linux/include/host_defines.h to accept the Fedora default compiler. * Install the appropriate gcc version for CentOS developper toolset. Please see https://www.softwarecollections.org/en/scls/rhscl/devtoolset-4/

sudo dnf install http://ftp.ciril.fr/pub/linux/centos/7.3.1611/extras/x86_64/Packages/centos-release-scl-2-2.el7.centos.noarch.rpm
sudo dnf install devtoolset-4-toolchain

You cannot install the whole devtoolset-4 collection, but the toolchain is enough , then each time you need to build using cuda, you start by

scl run devtoolset-4 bash
gcc --version
gcc (GCC) 5.2.1 20150902 (Red Hat 5.2.1-2)
