Install CUDA Toolkit on Windows

The CUDA Toolkit is a software development platform created by NVIDIA that enables developers to harness the power of NVIDIA GPUs for parallel computing. CUDA stands for Compute Unified Device Architecture.

It includes libraries, compiler tools, and debugging utilities that allow applications to run faster by offloading tasks to the GPU. Whether you’re working in AI, machine learning, data science, or high-performance computing, the CUDA Toolkit provides everything you need to accelerate your applications using GPU computing.

Download CUDA Toolkit

To begin using the CUDA Toolkit on a Windows system, you need to download the appropriate installer from the official NVIDIA website. Follow these steps:

• Go to the official NVIDIA CUDA Toolkit Downloads page.
• Select your operating system as Windows.
• Choose your system architecture (e.g., x86_64), version (e.g., Windows 10, 11), and installer type (e.g., exe or local installer).
• Click the download link to save the installer to your system.

Install CUDA Toolkit

Once the installer is downloaded, you can install the CUDA Toolkit by following these steps:

• Double-click the downloaded installer to launch the setup wizard.
• Review and accept the license agreement.

• Choose Express installation for default options, or Custom to select specific components.

• The installer will automatically check your system for compatibility and install the required drivers and components.

• Choose or select the install location.

• Wait for the installation to complete and click Finish.

Verify the Installation

After installation, verify the CUDA Toolkit is installed correctly:

• Open the Windows Command Prompt.
• Type in the following command.
• /> nvcc --version and press Enter key.

• If the version information is displayed, the installation is successful.

Set Up Environment Variables

In most cases, the installer sets up the environment variables automatically. If not, you can do it manually:

• Open System Properties → Environment Variables.
• Add the CUDA bin folder path (e.g., C:\Program Files\NVIDIA GPU Computing Toolkit\CUDA\v12.5\bin) to the Path variable.
