NVIDIA CUDA Installation Guide for Linux

The installation instructions for the CUDA Toolkit on Linux.

1. Introduction

CUDA^® is a parallel computing platform and programming model invented by NVIDIA^®. It enables dramatic increases in computing performance by harnessing the power of the graphics processing unit (GPU).

CUDA was developed with several design goals in mind:

Provide a small set of extensions to standard programming languages, like C, that enable a straightforward implementation of parallel algorithms. With CUDA C/C++, programmers can focus on the task of parallelization of the algorithms rather than spending time on their implementation.
Support heterogeneous computation where applications use both the CPU and GPU. Serial portions of applications are run on the CPU, and parallel portions are offloaded to the GPU. As such, CUDA can be incrementally applied to existing applications. The CPU and GPU are treated as separate devices that have their own memory spaces. This configuration also allows simultaneous computation on the CPU and GPU without contention for memory resources.

CUDA-capable GPUs have hundreds of cores that can collectively run thousands of computing threads. These cores have shared resources including a register file and a shared memory. The on-chip shared memory allows parallel tasks running on these cores to share data without sending it over the system memory bus.

This guide will show you how to install and check the correct operation of the CUDA development tools.

Note

Instructions for installing NVIDIA Drivers are now in https://docs.nvidia.com/datacenter/tesla/driver-installation-guide/index.html.

1.1. System Requirements

To use NVIDIA CUDA on your system, you will need the following installed:

CUDA-capable GPU
A supported version of Linux with a gcc compiler and toolchain
CUDA Toolkit (available at https://developer.nvidia.com/cuda-downloads)

The CUDA development environment relies on tight integration with the host development environment, including the host compiler and C runtime libraries, and is therefore only supported on distribution versions that have been qualified for this CUDA Toolkit release.

The following table lists the supported Linux distributions. Please review the footnotes associated with the table.

For specific kernel versions supported on Red Hat Enterprise Linux (RHEL), visit https://access.redhat.com/articles/3078.

A list of kernel versions including the release dates for SUSE Linux Enterprise Server (SLES) is available at https://www.suse.com/support/kb/doc/?id=000019587.

Support for Debian 11.x is deprecated.

1.2. OS Support Policy

CUDA support for Ubuntu 20.04.x, Ubuntu 22.04.x, Ubuntu 24.04.x, RHEL 8.x, RHEL 9.x, Rocky Linux 8.x, Rocky Linux 9.x, SUSE SLES 15.x, OpenSUSE Leap 15.x, Amazon linux 2023, and Azure Linux 2.0 will be until the standard EOSS as defined for each OS. Please refer to the support lifecycle for these OSes to know their support timelines.
CUDA supports the latest Fedora release version. For Fedora release timelines, visit https://docs.fedoraproject.org/en-US/releases/.
CUDA supports a single KylinOS release version. For details, visit https://www.kylinos.cn/.

Refer to the support lifecycle for these supported OSes to know their support timelines and plan to move to newer releases accordingly.

1.3. Host Compiler Support Policy

In order to compile the CPU “Host” code in the CUDA source, the CUDA compiler NVCC requires a compatible host compiler to be installed on the system. The version of the host compiler supported on Linux platforms is tabulated as below. NVCC performs a version check on the host compiler’s major version and so newer minor versions of the compilers listed below will be supported, but major versions falling outside the range will not be supported.

Table 2 Supported Compilers
Distribution	GCC	Clang	NVHPC	XLC	ArmC/C++	ICC
x86_64	6.x - 13.2	7.x - 18.0	24.5	No	No	2021.7
Arm64 sbsa	6.x - 13.2	7.x - 18.0	24.5	No	24.04	No

For GCC and Clang, the preceding table indicates the minimum version and the latest version supported. If you are on a Linux distribution that may use an older version of GCC toolchain as default than what is listed above, it is recommended to upgrade to a newer toolchain CUDA 11.0 or later toolkit. Newer GCC toolchains are available with the Red Hat Developer Toolset for example. For platforms that ship a compiler version older than GCC 6 by default, linking to static or dynamic libraries that are shipped with the CUDA Toolkit is not supported. We only support libstdc++ (GCC’s implementation) for all the supported host compilers for the platforms listed above.

1.3.1. Supported C++ Dialects

NVCC and NVRTC (CUDA Runtime Compiler) support the following C++ dialect: C++11, C++14, C++17, C++20 on supported host compilers. The default C++ dialect of NVCC is determined by the default dialect of the host compiler used for compilation. Refer to host compiler documentation and the CUDA Programming Guide for more details on language support.

C++20 is supported with the following flavors of host compiler in both host and device code.

GCC	Clang	NVHPC	Arm C/C++
>=10.x	>=11.x	>=22.x	>=22.x

1.4. About This Document

This document is intended for readers familiar with the Linux environment and the compilation of C programs from the command line. You do not need previous experience with CUDA or experience with parallel computation. Note: This guide covers installation only on systems with X Windows installed.

Note

Many commands in this document might require superuser privileges. On most distributions of Linux, this will require you to log in as root. For systems that have enabled the sudo package, use the sudo prefix for all necessary commands.

2. Pre-installation Actions

Some actions must be taken before the CUDA Toolkit can be installed on Linux:

Verify the system has a CUDA-capable GPU.
Verify the system is running a supported version of Linux.
Verify the system has gcc installed.
Download the NVIDIA CUDA Toolkit.
Handle conflicting installation methods.

Note

You can override the install-time prerequisite checks by running the installer with the -override flag. Remember that the prerequisites will still be required to use the NVIDIA CUDA Toolkit.

2.1. Verify You Have a CUDA-Capable GPU

To verify that your GPU is CUDA-capable, go to your distribution’s equivalent of System Properties, or, from the command line, enter:

lspci | grep -i nvidia

If you do not see any settings, update the PCI hardware database that Linux maintains by entering update-pciids (generally found in /sbin) at the command line and rerun the previous lspci command.

If your graphics card is from NVIDIA and it is listed in https://developer.nvidia.com/cuda-gpus, your GPU is CUDA-capable.

The Release Notes for the CUDA Toolkit also contain a list of supported products.

2.2. Verify You Have a Supported Version of Linux

The CUDA Development Tools are only supported on some specific distributions of Linux. These are listed in the CUDA Toolkit release notes.

To determine which distribution and release number you’re running, type the following at the command line:

uname -m && cat /etc/*release

You should see output similar to the following, modified for your particular system:

x86_64
Red Hat Enterprise Linux Workstation release 6.0 (Santiago)

The x86_64 line indicates you are running on a 64-bit system. The remainder gives information about your distribution.

2.3. Verify the System Has gcc Installed

The gcc compiler is required for development using the CUDA Toolkit. It is not required for running CUDA applications. It is generally installed as part of the Linux installation, and in most cases the version of gcc installed with a supported version of Linux will work correctly.

To verify the version of gcc installed on your system, type the following on the command line:

gcc --version

If an error message displays, you need to install the development tools from your Linux distribution or obtain a version of gcc and its accompanying toolchain from the Web.

2.4. Choose an Installation Method

The CUDA Toolkit can be installed using either of two different installation mechanisms: distribution-specific packages (RPM and Deb packages), or a distribution-independent package (runfile packages).

The distribution-independent package has the advantage of working across a wider set of Linux distributions, but does not update the distribution’s native package management system. The distribution-specific packages interface with the distribution’s native package management system. It is recommended to use the distribution-specific packages, where possible.

Note

For both native as well as cross development, the toolkit must be installed using the distribution-specific installer. See the CUDA Cross-Platform Installation section for more details.

2.5. Download the NVIDIA CUDA Toolkit

The NVIDIA CUDA Toolkit is available at https://developer.nvidia.com/cuda-downloads.

Choose the platform you are using and download the NVIDIA CUDA Toolkit.

The CUDA Toolkit contains the tools needed to create, build and run a CUDA application as well as libraries, header files, and other resources.

Download Verification

The download can be verified by comparing the MD5 checksum posted at https://developer.download.nvidia.com/compute/cuda/12.6.2/docs/sidebar/md5sum.txt with that of the downloaded file. If either of the checksums differ, the downloaded file is corrupt and needs to be downloaded again.

To calculate the MD5 checksum of the downloaded file, run the following:

md5sum <file>

2.6. Handle Conflicting Installation Methods

Before installing CUDA, any previous installations that could conflict should be uninstalled. This will not affect systems which have not had CUDA installed previously, or systems where the installation method has been preserved (RPM/Deb vs. Runfile). See the following charts for specifics.

Table 3 CUDA Toolkit Installation Compatibility Matrix
		Installed Toolkit Version == X.Y		Installed Toolkit Version != X.Y
		RPM/Deb	run	RPM/Deb	run
Installing Toolkit Version X.Y	RPM/Deb	No Action	Uninstall Run	No Action	No Action
Installing Toolkit Version X.Y	run	Uninstall RPM/Deb	Uninstall Run	No Action	No Action

Use the following command to uninstall a Toolkit runfile installation:

sudo /usr/local/cuda-X.Y/bin/cuda-uninstaller

Use the following commands to uninstall an RPM/Deb installation:

sudo dnf remove <package_name>                      # RHEL 8 / Rocky Linux 8 / RHEL 9 / Rocky Linux 9 / Fedora / KylinOS 10 / Amazon Linux 2023

sudo tdnf remove <package_name>                     # Azure Linux

sudo zypper remove <package_name>                   # OpenSUSE / SLES

sudo apt-get --purge remove <package_name>          # Debian / Ubuntu

3. Package Manager Installation

Basic instructions can be found in the Quick Start Guide. Read on for more detailed instructions.

3.1. Overview

Installation using RPM or Debian packages interfaces with your system’s package management system. When using RPM or Debian local repo installers, the downloaded package contains a repository snapshot stored on the local filesystem in /var/. Such a package only informs the package manager where to find the actual installation packages, but will not install them.

If the online network repository is enabled, RPM or Debian packages will be automatically downloaded at installation time using the package manager: apt-get, dnf, tdnf, or zypper.

Distribution-specific instructions detail how to install CUDA:

Finally, some helpful package manager capabilities are detailed.

These instructions are for native development only. For cross-platform development, see the CUDA Cross-Platform Environment section.

Note

Optional components such as nvidia-fs, libnvidia_nscq, and fabricmanager are not installed by default and will have to be installed separately as needed.

3.12. Additional Package Manager Capabilities

Below are some additional capabilities of the package manager that users can take advantage of.

3.12.1. Available Packages

The recommended installation package is the cuda package. This package will install the full set of other CUDA packages required for native development and should cover most scenarios.

The cuda package installs all the available packages for native developments. That includes the compiler, the debugger, the profiler, the math libraries, and so on. For x86_64 platforms, this also includes Nsight Eclipse Edition and the visual profilers.

On supported platforms, the cuda-cross-aarch64 and cuda-cross-sbsa packages install all the packages required for cross-platform development to arm64-Jetson and arm64-Server, respectively.

Note

32-bit compilation native and cross-compilation is removed from CUDA 12.0 and later Toolkit. Use the CUDA Toolkit from earlier releases for 32-bit compilation. Hopper does not support 32-bit applications.

The packages installed by the packages above can also be installed individually by specifying their names explicitly. The list of available packages be can obtained with:

dnf --disablerepo="*" --enablerepo="cuda*" list available    # Amazon Linux / Fedora / KylinOS / RHEL / Rocky Linux

tdnf --disablerepo="*" --enablerepo="cuda-cm2-<cuda X-Y version>-local" list available   # Azure Linux

zypper packages -r cuda                                      # OpenSUSE / SLES

cat /var/lib/apt/lists/*cuda*Packages | grep "Package:"      # Debian / Ubuntu

3.12.2. Meta Packages

Meta packages are RPM/Deb/Conda packages which contain no (or few) files but have multiple dependencies. They are used to install many CUDA packages when you may not know the details of the packages you want. The following table lists the meta packages.

Table 4 Meta Packages Available for CUDA 12.6
Meta Package	Purpose
cuda	Installs all CUDA Toolkit and Driver packages. Handles upgrading to the next version of the `cuda` package when it’s released.
cuda-12-6	Installs all CUDA Toolkit and Driver packages. Remains at version 12.5 until an additional version of CUDA is installed.
cuda-toolkit-12-6	Installs all CUDA Toolkit packages required to develop CUDA applications. Does not include the driver.
cuda-toolkit-16	Installs all CUDA Toolkit packages required to develop applications. Will not upgrade beyond the 12.x series toolkits. Does not include the driver.
cuda-toolkit	Installs all CUDA Toolkit packages required to develop applications. Handles upgrading to the next 12.x version of CUDA when it’s released. Does not include the driver.
cuda-tools-12-6	Installs all CUDA command line and visual tools.
cuda-runtime-12-6	Installs all CUDA Toolkit packages required to run CUDA applications, as well as the Driver packages.
cuda-compiler-12-6	Installs all CUDA compiler packages.
cuda-libraries-12-6	Installs all runtime CUDA Library packages.
cuda-libraries-dev-12-6	Installs all development CUDA Library packages.

3.12.3. Package Upgrades

The cuda package points to the latest stable release of the CUDA Toolkit. When a new version is available, use the following commands to upgrade the toolkit:

3.12.3.1. Amazon Linux

sudo dnf upgrade cuda-toolkit

3.12.3.2. Fedora

When upgrading the toolkit to a new major branch:

sudo dnf install cuda-toolkit

When upgrading the toolkit to a new minor branch:

sudo dnf upgrade cuda-toolkit

3.12.3.3. KylinOS / RHEL / Rocky Linux

sudo dnf install cuda-toolkit

3.12.3.4. Azure Linux

sudo tdnf install cuda-toolkit

3.12.3.5. OpenSUSE / SLES

sudo zypper install cuda-toolkit

3.12.3.6. Debian / Ubuntu

sudo apt-get install cuda-toolkit

3.12.3.7. Other Package Notes

The cuda-cross-<arch> packages can also be upgraded in the same manner.

Some desktop environments, such as GNOME or KDE, will display a notification alert when new packages are available.

To avoid any automatic upgrade, and lock down the toolkit installation to the X.Y release, install the cuda-toolkit-X-Y or cuda-cross-<arch>-X-Y package.

Side-by-side installations are supported. For instance, to install both the X.Y CUDA Toolkit and the X.Y+1 CUDA Toolkit, install the cuda-toolkit-X.Y and cuda-toolkit-X.Y+1 packages.

4. Driver Installation

More information about driver installation can be found in the Driver Installation Guide for Linux

5. Runfile Installation

Basic instructions can be found in the Quick Start Guide. Read on for more detailed instructions.

This section describes the installation and configuration of CUDA when using the standalone installer. The standalone installer is a .run file and is completely self-contained.

5.1. Runfile Overview

The Runfile installation installs the CUDA Toolkit via an interactive ncurses-based interface.

The installation steps are listed below.

Finally, advanced options for the installer and uninstallation steps are detailed below.

The Runfile installation does not include support for cross-platform development. For cross-platform development, see the CUDA Cross-Platform Environment section.

5.2. Installation

Perform the pre-installation actions.
Reboot into text mode (runlevel 3).

This can usually be accomplished by adding the number “3” to the end of the system’s kernel boot parameters.

Since the NVIDIA drivers are not yet installed, the text terminals may not display correctly. Temporarily adding “nomodeset” to the system’s kernel boot parameters may fix this issue.

Consult your system’s bootloader documentation for information on how to make the above boot parameter changes.
Run the installer and follow the on-screen prompts:
```
sudo sh cuda_<version>_linux.run
```
The installer will prompt for the following:
- EULA Acceptance
- CUDA Toolkit installation, location, and /usr/local/cuda symbolic link
The default installation location for the toolkit is /usr/local/cuda-12.6:

The /usr/local/cuda symbolic link points to the location where the CUDA Toolkit was installed. This link allows projects to use the latest CUDA Toolkit without any configuration file update.

The installer must be executed with sufficient privileges to perform some actions. When the current privileges are insufficient to perform an action, the installer will ask for the user’s password to attempt to install with root privileges. Actions that cause the installer to attempt to install with root privileges are:
- installing the CUDA Toolkit to a location the user does not have permission to write to
- creating the /usr/local/cuda symbolic link
Running the installer with sudo, as shown above, will give permission to install to directories that require root permissions. Directories and files created while running the installer with sudo will have root ownership.
Reboot the system to reload the graphical interface:
```
sudo reboot
```
Perform the post-installation actions.

5.3. Advanced Options

Action	Options Used	Explanation
Silent Installation	`--silent`	Required for any silent installation. Performs an installation with no further user-input and minimal command-line output based on the options provided below. Silent installations are useful for scripting the installation of CUDA. Using this option implies acceptance of the EULA. The following flags can be used to customize the actions taken during installation. At least one of `--driver`, `--uninstall`, and `--toolkit` must be passed if running with non-root permissions.
	`--driver`	Install the CUDA Driver.
	`--toolkit`	Install the CUDA Toolkit.
	`--toolkitpath=<path>`	Install the CUDA Toolkit to the <path> directory. If not provided, the default path of `/usr/local/cuda-12.6` is used.
	`--defaultroot=<path>`	Install libraries to the <path> directory. If the <path> is not provided, then the default path of your distribution is used. This only applies to the libraries installed outside of the CUDA Toolkit path.
Extraction	`--extract=<path>`	Extracts to the <path> the following: the driver runfile, the raw files of the toolkit to <path>. This is especially useful when one wants to install the driver using one or more of the command-line options provided by the driver installer which are not exposed in this installer.
Overriding Installation Checks	`--override`	Ignores compiler, third-party library, and toolkit detection checks which would prevent the CUDA Toolkit from installing.
No OpenGL Libraries	`--no-opengl-libs`	Prevents the driver installation from installing NVIDIA’s GL libraries. Useful for systems where the display is driven by a non-NVIDIA GPU. In such systems, NVIDIA’s GL libraries could prevent X from loading properly.
No man pages	`--no-man-page`	Do not install the man pages under `/usr/share/man`.
Overriding Kernel Source	`--kernel-source-path=<path>`	Tells the driver installation to use <path> as the kernel source directory when building the NVIDIA kernel module. Required for systems where the kernel source is installed to a non-standard location.
Running nvidia-xconfig	`--run-nvidia-xconfig`	Tells the driver installation to run nvidia-xconfig to update the system X configuration file so that the NVIDIA X driver is used. The pre-existing X configuration file will be backed up.
No nvidia-drm kernel module	`--no-drm`	Do not install the nvidia-drm kernel module. This option should only be used to work around failures to build or install the nvidia-drm kernel module on systems that do not need the provided features.
Custom Temporary Directory Selection	`--tmpdir=<path>`	Performs any temporary actions within <path> instead of `/tmp`. Useful in cases where `/tmp` cannot be used (doesn’t exist, is full, is mounted with ‘noexec’, etc.).
Kernel Module Build Directory	`--kernel-module-build-directory=<kernel\|kernel-open>`	Tells the driver installation to use legacy or open flavor of kernel source when building the NVIDIA kernel module. The kernel-open flavor is only supported on Turing GPUs and newer.
	`-m=kernel`	Tells the driver installation to use legacy flavor of kernel source when building the NVIDIA kernel module. Shorthand for `--kernel-module-build-directory=kernel`
	`m=kernel-open`	Tells the driver installation to use open flavor of kernel source when building the NVIDIA kernel module. The kernel-open flavor is only supported on Turing GPUs and newer. Shorthand for `--kernel-module-build-directory=kernel-open`
Show Installer Options	`--help`	Prints the list of command-line options to stdout.

5.4. Uninstallation

To uninstall the CUDA Toolkit, run the uninstallation script provided in the bin directory of the toolkit. By default, it is located in /usr/local/cuda-12.6/bin:

sudo /usr/local/cuda-12.6/bin/cuda-uninstaller

6. Conda Installation

This section describes the installation and configuration of CUDA when using the Conda installer. The Conda packages are available at https://anaconda.org/nvidia.

6.1. Conda Overview

The Conda installation installs the CUDA Toolkit. The installation steps are listed below.

6.2. Installing CUDA Using Conda

To perform a basic install of all CUDA Toolkit components using Conda, run the following command:

conda install cuda -c nvidia

6.3. Uninstalling CUDA Using Conda

To uninstall the CUDA Toolkit using Conda, run the following command:

conda remove cuda

6.4. Installing Previous CUDA Releases

All Conda packages released under a specific CUDA version are labeled with that release version. To install a previous version, include that label in the install command such as:

conda install cuda -c nvidia/label/cuda-11.3.0

6.5. Upgrading from cudatoolkit Package

If you had previously installed CUDA using the cudatoolkit package and want to maintain a similar install footprint, you can limit your installation to the following packages:

cuda-libraries-dev
cuda-nvcc
cuda-nvtx
cuda-cupti

Note

Some extra files, such as headers, will be included in this installation which were not included in the cudatoolkit package. If you need to reduce your installation further, replace cuda-libraries-dev with the specific libraries you need.

7. Pip Wheels

NVIDIA provides Python Wheels for installing CUDA through pip, primarily for using CUDA with Python. These packages are intended for runtime use and do not currently include developer tools (these can be installed separately).

Please note that with this installation method, CUDA installation environment is managed via pip and additional care must be taken to set up your host environment to use CUDA outside the pip environment.

Prerequisites

To install Wheels, you must first install the nvidia-pyindex package, which is required in order to set up your pip installation to fetch additional Python modules from the NVIDIA NGC PyPI repo. If your pip and setuptools Python modules are not up-to-date, then use the following command to upgrade these Python modules. If these Python modules are out-of-date then the commands which follow later in this section may fail.

python3 -m pip install --upgrade setuptools pip wheel

You should now be able to install the nvidia-pyindex module.

python3 -m pip install nvidia-pyindex

If your project is using a requirements.txt file, then you can add the following line to your requirements.txt file as an alternative to installing the nvidia-pyindex package:

--extra-index-url https://pypi.org/simple

Procedure

Install the CUDA runtime package:

python3 -m pip install nvidia-cuda-runtime-cu12

Optionally, install additional packages as listed below using the following command:

python3 -m pip install nvidia-<library>

Metapackages

The following metapackages will install the latest version of the named component on Linux for the indicated CUDA version. “cu12” should be read as “cuda12”.

nvidia-cuda-runtime-cu12
nvidia-cuda-cccl-cu12
nvidia-cuda-cupti-cu12

8. CUDA Cross-Platform Environment

Cross development for arm64-sbsa is supported on Ubuntu 20.04, Ubuntu 22.04, Ubuntu 24.04, KylinOS 10, RHEL 8, RHEL 9, and SLES 15.

Cross development for arm64-Jetson is only supported on Ubuntu 22.04

We recommend selecting a host development environment that matches the supported cross-target environment. This selection helps prevent possible host/target incompatibilities, such as GCC or GLIBC version mismatches.

8.1. CUDA Cross-Platform Installation

Some of the following steps may have already been performed as part of the native installation sections. Such steps can safely be skipped.

These steps should be performed on the x86_64 host system, rather than the target system. To install the native CUDA Toolkit on the target system, refer to the native installation sections in Package Manager Installation.

9. Tarball and Zip Archive Deliverables

In an effort to meet the needs of a growing customer base requiring alternative installer packaging formats, as well as a means of input into community CI/CD systems, tarball and zip archives are available for each component.

These tarball and zip archives, known as binary archives, are provided at https://developer.download.nvidia.com/compute/cuda/redist/.

These component .tar.xz and .zip binary archives do not replace existing packages such as .deb, .rpm, runfile, conda, etc. and are not meant for general consumption, as they are not installers. However this standardized approach will replace existing .txz archives.

For each release, a JSON manifest is provided such as redistrib_11.4.2.json, which corresponds to the CUDA 11.4.2 release label (CUDA 11.4 update 2) which includes the release date, the name of each component, license name, relative URL for each platform and checksums.

Package maintainers are advised to check the provided LICENSE for each component prior to redistribution. Instructions for developers using CMake and Bazel build systems are provided in the next sections.

9.1. Parsing Redistrib JSON

The following example of a JSON manifest contains keys for each component: name, license, version, and a platform array which includes relative_path, sha256, md5, and size (bytes) for each archive.

9.2. Importing Tarballs into CMake

The recommended module for importing these tarballs into the CMake build system is via FindCUDAToolkit (3.17 and newer).

Note

The FindCUDA module is deprecated.

The path to the extraction location can be specified with the CUDAToolkit_ROOT environmental variable. For example CMakeLists.txt and commands, see cmake/1_FindCUDAToolkit/.

For older versions of CMake, the ExternalProject_Add module is an alternative method. For example CMakeLists.txt file and commands, see cmake/2_ExternalProject/.

9.3. Importing Tarballs into Bazel

The recommended method of importing these tarballs into the Bazel build system is using http_archive and pkg_tar.

For an example, see bazel/1_pkg_tar/.

10. Post-installation Actions

The post-installation actions must be manually performed. These actions are split into mandatory, recommended, and optional sections.

10.1. Mandatory Actions

Some actions must be taken after the installation before the CUDA Toolkit can be used.

10.1.1. Environment Setup

The PATH variable needs to include export PATH=/usr/local/cuda-12.6/bin${PATH:+:${PATH}}. Nsight Compute has moved to /opt/nvidia/nsight-compute/ only in rpm/deb installation method. When using .run installer it is still located under /usr/local/cuda-12.6/.

To add this path to the PATH variable:

export PATH=/usr/local/cuda-12.6/bin${PATH:+:${PATH}}

In addition, when using the runfile installation method, the LD_LIBRARY_PATH variable needs to contain /usr/local/cuda-12.6/lib64 on a 64-bit system, or /usr/local/cuda-12.6/lib on a 32-bit system

To change the environment variables for 64-bit operating systems:

export LD_LIBRARY_PATH=/usr/local/cuda-12.6/lib64\
                         ${LD_LIBRARY_PATH:+:${LD_LIBRARY_PATH}}

To change the environment variables for 32-bit operating systems:

export LD_LIBRARY_PATH=/usr/local/cuda-12.6/lib\
                         ${LD_LIBRARY_PATH:+:${LD_LIBRARY_PATH}}

Note that the above paths change when using a custom install path with the runfile installation method.

10.2. Recommended Actions

Other actions are recommended to verify the integrity of the installation.

10.2.1. Install Writable Samples

CUDA Samples are now located in https://github.com/nvidia/cuda-samples, which includes instructions for obtaining, building, and running the samples.

10.2.2. Verify the Installation

Before continuing, it is important to verify that the CUDA toolkit can find and communicate correctly with the CUDA-capable hardware. To do this, you need to compile and run some of the sample programs, located in https://github.com/nvidia/cuda-samples.

Note

Ensure the PATH and, if using the runfile installation method, LD_LIBRARY_PATH variables are set correctly.

10.2.2.1. Running the Binaries

After compilation, find and run deviceQueryfrom https://github.com/nvidia/cuda-samples. If the CUDA software is installed and configured correctly, the output for deviceQuery should look similar to that shown in Figure 1.

Figure 1 Valid Results from deviceQuery CUDA Sample

The exact appearance and the output lines might be different on your system. The important outcomes are that a device was found (the first highlighted line), that the device matches the one on your system (the second highlighted line), and that the test passed (the final highlighted line).

If a CUDA-capable device is installed but deviceQuery reports that no CUDA-capable devices are present, this likely means that the /dev/nvidia* files are missing or have the wrong permissions.

On systems where SELinux is enabled, you might need to temporarily disable this security feature to run deviceQuery. To do this, type:

setenforce 0

from the command line as the superuser.

Running the bandwidthTest program ensures that the system and the CUDA-capable device are able to communicate correctly. Its output is shown in Figure 2.

Figure 2 Valid Results from bandwidthTest CUDA Sample

Note that the measurements for your CUDA-capable device description will vary from system to system. The important point is that you obtain measurements, and that the second-to-last line (in Figure 2) confirms that all necessary tests passed.

Should the tests not pass, make sure you have a CUDA-capable NVIDIA GPU on your system and make sure it is properly installed.

If you run into difficulties with the link step (such as libraries not being found), consult the Linux Release Notes found in https://github.com/nvidia/cuda-samples.

10.2.3. Install Nsight Eclipse Plugins

To install Nsight Eclipse plugins, an installation script is provided:

/usr/local/cuda-12.6/bin/nsight_ee_plugins_manage.sh install <eclipse-dir>

Refer to Nsight Eclipse Plugins Installation Guide for more details.

10.2.4. Local Repo Removal

Removal of the local repo installer is recommended after installation of CUDA SDK.

Debian / Ubuntu

sudo apt-get remove --purge "cuda-repo-<distro>-X-Y-local*"

Amazon Linux / Fedora / KylinOS / RHEL / Rocky Linux

sudo dnf remove "cuda-repo-<distro>-X-Y-local*"

Azure Linux

sudo tdnf remove "cuda-repo-<distro>-X-Y-local*"

OpenSUSE / SLES

sudo zypper remove "cuda-repo-<distro>-X-Y-local*"

10.3. Optional Actions

Other options are not necessary to use the CUDA Toolkit, but are available to provide additional features.

10.3.1. Install Third-party Libraries

Some CUDA samples use third-party libraries which may not be installed by default on your system. These samples attempt to detect any required libraries when building.

If a library is not detected, it waives itself and warns you which library is missing. To build and run these samples, you must install the missing libraries. In cases where these dependencies are not installed, follow the instructions below.

Amazon Linux / Fedora / KylinOS / RHEL / Rocky Linux

sudo dnf install freeglut-devel libX11-devel libXi-devel libXmu-devel \
    make mesa-libGLU-devel freeimage-devel libglfw3-devel

SLES

sudo zypper install libglut3 libX11-devel libXi6 libXmu6 libGLU1 make

OpenSUSE

sudo zypper install freeglut-devel libX11-devel libXi-devel libXmu-devel \
    make Mesa-libGL-devel freeimage-devel

Debian / Ubuntu

sudo apt-get install g++ freeglut3-dev build-essential libx11-dev \
    libxmu-dev libxi-dev libglu1-mesa-dev libfreeimage-dev libglfw3-dev

10.3.2. Install the Source Code for cuda-gdb

The cuda-gdb source must be explicitly selected for installation with the runfile installation method. During the installation, in the component selection page, expand the component “CUDA Tools 12.6” and select cuda-gdb-src for installation. It is unchecked by default.

To obtain a copy of the source code for cuda-gdb using the RPM and Debian installation methods, the cuda-gdb-src package must be installed.

The source code is installed as a tarball in the /usr/local/cuda-12.6/extras directory.

10.3.3. Select the Active Version of CUDA

For applications that rely on the symlinks /usr/local/cuda and /usr/local/cuda-MAJOR, you may wish to change to a different installed version of CUDA using the provided alternatives.

To show the active version of CUDA and all available versions:

update-alternatives --display cuda

To show the active minor version of a given major CUDA release:

update-alternatives --display cuda-12

To update the active version of CUDA:

sudo update-alternatives --config cuda

11. Removing CUDA Toolkit

12. Advanced Setup

Below is information on some advanced setup scenarios which are not covered in the basic instructions above.

Table 6 Advanced Setup Scenarios when Installing CUDA
Scenario	Instructions
Install CUDA to a specific directory using the Package Manager installation method.	RPM The RPM packages don’t support custom install locations through the package managers (Yum and Zypper), but it is possible to install the RPM packages to a custom location using rpm’s `--relocate` parameter: sudo rpm --install --relocate /usr/local/cuda-12.6=/new/toolkit package.rpm You will need to install the packages in the correct dependency order; this task is normally taken care of by the package managers. For example, if package “foo” has a dependency on package “bar”, you should install package “bar” first, and package “foo” second. You can check the dependencies of a RPM package as follows: rpm -qRp package.rpm Note that the driver packages cannot be relocated. Deb The Deb packages do not support custom install locations. It is however possible to extract the contents of the Deb packages and move the files to the desired install location. See the next scenario for more details one xtracting Deb packages.
Extract the contents of the installers.	Runfile The Runfile can be extracted into the standalone Toolkit Runfiles by using the `--extract` parameter. The Toolkit standalone Runfiles can be further extracted by running: ./runfile.run --tar mxvf ./runfile.run -x RPM The RPM packages can be extracted by running: rpm2cpio package.rpm \| cpio -idmv Deb The Deb packages can be extracted by running: dpkg-deb -x package.deb output_dir
Modify Ubuntu’s apt package manager to query specific architectures for specific repositories. This is useful when a foreign architecture has been added, causing “404 Not Found” errors to appear when the repository meta-data is updated.	Each repository you wish to restrict to specific architectures must have its `sources.list` entry modified. This is done by modifying the `/etc/apt/sources.list` file and any files containing repositories you wish to restrict under the `/etc/apt/sources.list.d/` directory. Normally, it is sufficient to modify only the entries in `/etc/apt/sources.list` An architecture-restricted repository entry looks like: deb [arch=<arch1>,<arch2>] <url> For example, if you wanted to restrict a repository to only the amd64 and i386 architectures, it would look like: deb [arch=amd64,i386] <url> It is not necessary to restrict the `deb-src` repositories, as these repositories don’t provide architecture-specific packages. For more details, see the `sources.list` manpage.
The runfile installer fails to extract due to limited space in the TMP directory.	This can occur on systems with limited storage in the TMP directory (usually `/tmp`), or on systems which use a tmpfs in memory to handle temporary storage. In this case, the `--tmpdir` command-line option should be used to instruct the runfile to use a directory with sufficient space to extract into. More information on this option can be found here.
In case of the error: `E: Failed to fetch file:/var/cuda-repo File not found`	Debian and Ubuntu This can occur when installing CUDA after uninstalling a different version. Use the following command before installation: sudo rm -v /var/lib/apt/lists/cuda /var/lib/apt/lists/nvidia
Verbose installation on Debian and Ubuntu	Use the `--verbose-versions` flag, for example: sudo apt-get install --verbose-versions cuda

13. Additional Considerations

Now that you have CUDA-capable hardware and the NVIDIA CUDA Toolkit installed, you can examine and enjoy the numerous included programs. To begin using CUDA to accelerate the performance of your own applications, consult the CUDA C++ Programming Guide, located in /usr/local/cuda-12.6/doc.

A number of helpful development tools are included in the CUDA Toolkit to assist you as you develop your CUDA programs, such as NVIDIA^® Nsight™ Eclipse Edition, NVIDIA Visual Profiler, CUDA-GDB, and CUDA-MEMCHECK.

For technical support on programming questions, consult and participate in the developer forums at https://forums.developer.nvidia.com/c/accelerated-computing/cuda/206.

14. Frequently Asked Questions

14.1. How do I install the Toolkit in a different location?

The Runfile installation asks where you wish to install the Toolkit during an interactive install. If installing using a non-interactive install, you can use the --toolkitpath parameter to change the install location:

./runfile.run --silent \
                --toolkit --toolkitpath=/my/new/toolkit

The RPM and Deb packages cannot be installed to a custom install location directly using the package managers. See the “Install CUDA to a specific directory using the Package Manager installation method” scenario in the Advanced Setup section for more information.

14.2. Why do I see “nvcc: No such file or directory” when I try to build a CUDA application?

Your PATH environment variable is not set up correctly. Ensure that your PATH includes the bin directory where you installed the Toolkit, usually /usr/local/cuda-12.6/bin.

export PATH=/usr/local/cuda-12.6/bin${PATH:+:${PATH}}

14.3. Why do I see “error while loading shared libraries: <lib name>: cannot open shared object file: No such file or directory” when I try to run a CUDA application that uses a CUDA library?

Your LD_LIBRARY_PATH environment variable is not set up correctly. Ensure that your LD_LIBRARY_PATH includes the lib and/or lib64 directory where you installed the Toolkit, usually /usr/local/cuda-12.6/lib{,64}:

export LD_LIBRARY_PATH=/usr/local/cuda-12.6/lib\
                         ${LD_LIBRARY_PATH:+:${LD_LIBRARY_PATH}}

14.4. Why do I see multiple “404 Not Found” errors when updating my repository meta-data on Ubuntu?

These errors occur after adding a foreign architecture because apt is attempting to query for each architecture within each repository listed in the system’s sources.list file. Repositories that do not host packages for the newly added architecture will present this error. While noisy, the error itself does no harm. Please see the Advanced Setup section for details on how to modify your sources.list file to prevent these errors.

14.5. How can I tell X to ignore a GPU for compute-only use?

To make sure X doesn’t use a certain GPU for display, you need to specify which other GPU to use for display. For more information, please refer to the “Use a specific GPU for rendering the display” scenario in the Advanced Setup section.

14.6. Why doesn’t the cuda-repo package install the CUDA Toolkit?

When using RPM or Deb, the downloaded package is a repository package. Such a package only informs the package manager where to find the actual installation packages, but will not install them.

See the Package Manager Installation section for more details.

14.7. How do I install an older CUDA version using a network repo?

Depending on your system configuration, you may not be able to install old versions of CUDA using the cuda metapackage. In order to install a specific version of CUDA, you may need to specify all of the packages that would normally be installed by the cuda metapackage at the version you want to install.

If you are using yum to install certain packages at an older version, the dependencies may not resolve as expected. In this case you may need to pass “--setopt=obsoletes=0” to yum to allow an install of packages which are obsoleted at a later version than you are trying to install.

14.8. How do I handle “Errors were encountered while processing: glx-diversions”?

This sometimes occurs when trying to uninstall CUDA after a clean .deb installation. Run the following commands:

sudo apt-get install glx-diversions --reinstall
sudo apt-get remove nvidia-alternative

Then re-run the commands from Removing CUDA Toolkit.
