How to install NVIDIA CUDA Toolkit on Fedora 28 Linux

The Nvidia CUDA toolkit is an extension of the GPU parallel computing platform and programming model. The Nvidia CUDA installation consists of inclusion of the official Nvidia CUDA repository followed by the installation of relevant meta package.

In this How to install NVIDIA CUDA Toolkit on Fedora 28 Linux tutorial you will learn:

• How to download the latest NVIDIA CUDA repository package.
• How to install the CUDA repository package on Fedora 28.
• How to select and install a CUDA meta package on Fedora 28.
• How to export system path to the Nvidia CUDA binary executables.
• How to confirm and test your CUDA installation.

How to install NVIDIA CUDA Toolkit on Fedora 28 Linux step by step instructions

1. Download the latest Nvidia CUDA repository package cuda-repo-fedora*.rpm. For example use the wget command to download the latest CUDA package which is at the time of writing CUDA version 10:

   $ wget https://developer.download.nvidia.com/compute/cuda/repos/fedora27/x86_64/cuda-repo-fedora27-10.0.130-1.x86_64.rpm
   

   The package should now be available within your home directory:

   $ ls cuda-repo-fedora27-10.0.130-1.x86_64.rpm
   cuda-repo-fedora27-10.0.130-1.x86_64.rpm
   

2. Install the CUDA repository package. This will enable CUDA repository on your Fedora 28 Linux system:

   $ sudo rpm -i cuda-repo-*.rpm
   

3. Select CUDA meta package you wish to install based on the below table. For example the below command will install the entire CUDA toolkit and driver packages:

   $ sudo dnf install cuda
   

   Example of Meta Packages Available for CUDA 10.0. Reference: NVIDIA.com

   Package name	Description
   cuda	Installs all CUDA Toolkit and Driver packages. Handles upgrading to the next version of the cuda package when it's released.
   cuda-10.0	Installs all CUDA Toolkit and Driver packages. Remains at version 10.0 until an additional version of CUDA is installed.
   cuda-toolkit-10.0	Installs all CUDA Toolkit packages required to develop CUDA applications. Does not include the driver.
   cuda-tools-10.0	Installs all CUDA command line and visual tools.
   cuda-runtime-10.0	Installs all CUDA Toolkit packages required to run CUDA applications, as well as the Driver packages.
   cuda-compiler-10.0	Installs all CUDA compiler packages.
   cuda-libraries-10.0	Installs all runtime CUDA Library packages.
   cuda-libraries-dev-10.0	Installs all development CUDA Library packages.
   cuda-drivers	Installs all Driver packages. Handles upgrading to the next version of the Driver packages when they're released.

4. Export system path to Nvidia CUDA binary executables. Open ~/.bashrc using your preferred text editor and add the following two lines:

   export PATH=/usr/local/cuda/bin:$PATH
   export LD_LIBRARY_PATH=/usr/local/cuda/lib64:$LD_LIBRARY_PATH
   

   ---

   ---

5. Re-login or read your updated ~/.bashrc file:

   $ source ~/.bashrc
   

6. Confirm the correct CUDA installation:

   $ nvcc --version
   $ nvidia-smi
   

7. Perform further tests by compiling your first CUDA program:

   $ mkdir cuda-samples
   $ cuda-install-samples-10.0.sh cuda-samples/
   $ cd cuda-samples/NVIDIA_CUDA-10.0_Samples/0_Simple/clock
   $ make
   

   Appendix

   At the time of writing gcc versions later than 7 are not supported by CUDA. From this reason you might receive the following error when attempting to compile CUDA program:

    In file included from /usr/local/cuda-10.0/bin/../targets/x86_64-linux/include/cuda_runtime.h:83,
                    from :
   /usr/local/cuda-10.0/bin/../targets/x86_64-linux/include/crt/host_config.h:129:2: error: #error -- unsupported GNU version! gcc versions later than 7 are not supported!
    #error -- unsupported GNU version! gcc versions later than 7 are not supported!
   

   WARNING
   Downgrading GCC may in many cases be destructive. Make sure that you know what you are doing.
   The following command can be used to downgrade GCC to version 7:

   $ sudo dnf --releasever=27 install gcc-7.3.1-6.fc27
