Installation

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

NVIDIA official repositories

These repositories contain versions of CUDA that are parallel installables along with another version.

CUDA Toolkit

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

  • RHEL/CentOS 7

    sudo yum install https://developer.download.nvidia.com/compute/cuda/repos/rhel7/x86_64/cuda-repo-rhel7-10.1.105-1.x86_64.rpm
    sudo yum install cuda
  • RHEL/CentOS 6

    sudo yum install https://developer.download.nvidia.com/compute/cuda/repos/rhel6/x86_64/cuda-repo-rhel6-10.1.105-1.x86_64.rpm
    sudo yum install cuda
  • Fedora 29 (and later)

    sudo dnf install https://developer.download.nvidia.com/compute/cuda/repos/fedora29/x86_64/cuda-repo-fedora29-10.1.105-1.x86_64.rpm
    sudo dnf install cuda

Machine Learning repository

Please use the official link: https://developer.nvidia.com/nccl/nccl-download

  • RHEL/CentOS 7

    sudo yum install https://developer.download.nvidia.com/compute/machine-learning/repos/rhel7/x86_64/nvidia-machine-learning-repo-rhel7-1.0.0-1.x86_64.rpm
    sudo yum install libcudnn7 libcudnn7-devel libnccl libnccl-devel
  • Fedora

    sudo dnf install https://developer.download.nvidia.com/compute/machine-learning/repos/rhel7/x86_64/nvidia-machine-learning-repo-rhel7-1.0.0-1.x86_64.rpm
    sudo dnf install libcudnn7 libcudnn7-devel libnccl libnccl-devel

Legacy NVIDIA 340xx/CUDA 6.5

This repository contains a legacy version of CUDA 6.5 that will works with the NVIDIA 340xx serie

Please use the Official link: https://developer.nvidia.com/cuda-toolkit-65

  • RHEL/CentOS 6

    sudo yum install http://developer.download.nvidia.com/compute/cuda/repos/rhel6/x86_64/cuda-repo-rhel6-6.5-14.x86_64.rpm
    sudo yum install cuda
  • Fedora 20 (and later)

    sudo yum install install http://developer.download.nvidia.com/compute/cuda/repos/fedora20/x86_64/cuda-repo-fedora20-6.5-14.x86_64.rpm
    sudo yum install cuda

Please verify to have a compatible compiler.

Known issues

GCC version

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:

sudo dnf install http://centos.mirrors.ovh.net/ftp.centos.org/7/extras/x86_64/Packages/centos-release-scl-rh-2-2.el7.centos.noarch.rpm
sudo dnf install http://centos.mirrors.ovh.net/ftp.centos.org/7/updates/x86_64/Packages/libgfortran4-7.2.1-1.2.1.el7_5.x86_64.rpm
sudo dnf install devtoolset-7-toolchain

You cannot install the whole devtoolset-7 collection, but the toolchain is enough , then each time you need to build using cuda, you start by

scl run devtoolset-7 bash
gcc --version
gcc (GCC) 7.3.1 20180303 (Red Hat 7.3.1-5)

exit
gcc --version
gcc (GCC) 8.1.1 20180712 (Red Hat 8.1.1-5)
Copyright (C) 2018 Free Software Foundation, Inc.

Which driver Package

Both "CUDA" and "RPM Fusion" repositories provide the nvidia driver packages. Usually, the package provided by RPM Fusion is higher. But in case you want to avoid the risk, add this:

#/etc/yum.repos.d/cuda.repo
[cuda]
name=cuda
...
exclude=akmod-nvidia*,kmod-nvidia*,*nvidia*,nvidia-*,cuda-nvidia-kmod-common,dkms-nvidia,nvidia-libXNVCtrl

NVIDIA provided libOpenCL

NVIDIA only advertise OpenCL 1.2 with the binary driver at this time. As a consequence, they provide an old version of libOpenCL.so.1 which works fine with their binary driver. As most software in Fedora and RPM Fusion are built using a newer libOpenCL, the system linker detects that and issues the following message:

 /usr/local/cuda-9.2/targets/x86_64-linux/lib/libOpenCL.so.1: no version information available (required by ffmpeg)

You can either ignore the message or manually delete the libOpenCL.so.1 provided by NVIDIA (run sudo ldconfig once deleted). Please verify to not have other OpenCL providers that might interfere with NVIDIA OpenCL usage. (looking at /etc/OpenCL/vendors ).

Running blender

Even when only running blender, you need a CUDA compatible compiler as described above. This is because blender will compile the "CUDA Kernels" optimized for your own GPU. You can run blender with:

 scl run devtoolset-7 blender

Once the "CUDA kernels" are compiled, you can run blender normally
