How to Install NVIDIA CUDA Toolkit?

The CUDA Toolkit is supported on most modern Linux distributions, Windows 7 or later and macOS 10.13 or later. I will cover the detailed instructions for installation on these operating systems.

Linux Installation

Most Linux distributions include CUDA in their package manager repositories. This makes installing the CUDA Toolkit very straightforward.

Here are the steps to install the latest version of the CUDA Toolkit on Linux:

Step 1: Verify System Requirements

• A desktop or workstation with NVIDIA GPU with CUDA compute capability 3.0 or higher.
• 64-bit Linux distribution with a glibc version later than 2.17. Consult the CUDA Installation Guide for specific version requirements.
• gcc compiler and toolchain.
• Up-to-date NVIDIA graphics drivers.

Step 2: Download the CUDA Toolkit

• Go to the CUDA Toolkit download page: https://developer.nvidia.com/cuda-downloads
• Choose the right package for your Linux distribution. For example, Ubuntu 18.04 would require:
• cuda-repo-ubuntu1804-10-2-local-10.2.89-440.33.01_1.0-1_amd64.deb
• Download the installer to your machine.

Step 3: Install the CUDA Toolkit

• Open a terminal and navigate to the download directory.
• Install the downloaded package with sudo dpkg -i [package name].
• Follow the on-screen prompts. Accept EULA and install the CUDA Toolkit components.
• The installation process will automatically attempt to install the NVIDIA graphics driver if a CUDA compatible version is not already present.

Step 4: Verify the Installation

• To verify that CUDA is installed and working correctly, compile and run a CUDA sample program:

cd /usr/local/cuda/samples/1_Utilities/deviceQuery
make
./deviceQuery

• This runs a small CUDA program to verify CUDA capabilites. If installed correctly, it will show detected NVIDIA GPUs and capabilities.

The CUDA Toolkit is now installed and ready to use! You can start writing your own CUDA programs or porting existing computational workloads to run on NVIDIA GPUs.

Windows Installation

On Windows platforms, the most straightforward method to install the CUDA Toolkit is by using the standalone Windows installer from NVIDIA.

Follow these steps for smooth installation on Windows:
