CUDA toolkit is an extension of the Graphics Processing Unit parallel computing architecture developed by NVIDIA. It also enhances the performance of the computer by using the power of the GPU. Programmers can use it through popular programming languages.

Here at Ibmi Media, as part of our Server Management Services, we regularly help our Customers to perform related NVIDIA queries.

In this context, we shall look into how to install CUDA on Ubuntu 20.04.

Steps to Install CUDA toolkit from the Ubuntu repository ?

1. Update system packages

To do this, run the below command:

$ sudo apt update

2. Install CUDA toolkit 

Now we start installing the CUDA toolkit by apt command:

$ sudo apt install nvidia-cuda-toolkit

How to Add CUDA to system PATH ?

Now that we have successfully installed CUDA on your Linux system, we must add CUDA to PATH, so that the shell knows where CUDA is located. Let's open the .profile file by vim command:

$ sudo vim ~/.profile

Then add the following lines to the end of the file and save:

# set PATH for cuda 10.1 installation
if [ -d "/usr/local/cuda-10.1/bin/" ]; then
export PATH=/usr/local/cuda-10.1/bin${PATH:+:${PATH}}
export LD_LIBRARY_PATH=/usr/local/cuda-10.1/lib64${LD_LIBRARY_PATH:+:${LD_LIBRARY_PATH}}
fi

After saving this file, reboot the system with the below command:

$ sudo reboot

How to Check your CUDA version ?

To do this, simply execute the below command:

$ nvcc --version
