How to install NVIDIA CUDA on Ubuntu 20.04?

Overview

CUDA (Compute Unified Device Architecture) is a parallel computing platform and programming style created by NVIDIA to speed up computational operations.

CUDA has a number of benefits, some of which are stated below:

1. CUDA-capable GPUs have hundreds of cores that can execute thousands of computational threads simultaneously. A number of technologies, including deep learning, are dominated by the combination of NVIDIA GPUs and CUDA, which also serves as the basis for the world's fastest computers.

2. Offer a condensed set of extensions to common programming languages, like C, that make it simple to build and implement parallel algorithms. C/C++ programmers can concentrate on parallelizing algorithms with CUDA rather than spending time on their implementation.

Learn step-by-step instructions on how to install NVIDIA CUDA on Ubuntu 20.04 for GPU acceleration and improved performance on deep learning tasks.

Get Started

Step 1: Move to the directory on your server to download CUDA 12 toolkit.

cd <download_directory>

Step 2: Download cuda-ubuntu.pin file.

wget https://developer.download.nvidia.com/compute/cuda/repos/ubuntu2004/x86_64/cuda-ubuntu2004.pin

Step 3: Move the cuda-ubuntu2004.pin file.

sudo mv cuda-ubuntu2004.pin /etc/apt/preferences.d/cuda-repository-pin-600

Step 4: Download NVIDIA CUDA for Ubuntu version 20.04 using the following code:

wget https://developer.download.nvidia.com/compute/cuda/12.0.0/local_installers/cuda-repo-ubuntu2004-12-0-local_12.0.0-525.60.13-1_amd64.deb

Step 5: Install CUDA 12 kit for Ubuntu version 20.04 using the following code:

sudo dpkg -i cuda-repo-ubuntu2004-12-0-local_12.0.0-525.60.13-1_amd64.deb

Step 6: Install the necessary keys for the software package's authentication using the following code:

The apt-key tool maintains the list of number of keys that apt uses to verify packages. Reliable packages are those that have undergone these keys' authentication.

sudo cp /var/cuda-repo-ubuntu2004-12-0-local/cuda-*-keyring.gpg /usr/share/keyrings/

Step 7: Use the following command to update software packages of CUDA.

sudo apt-get update

Step 8: Install CUDA using the below command:

sudo apt-get install
