This is the second part of CUDA-GPU tuning series where I’ll explain how to install CUDA Toolkit 10.1 on Ubuntu 18.04 LTS.

In the first part I’ve described how to properly install nVidia drivers on Ubuntu 18.04 LTS

Detailed instructions can be found on any of these two pages:

https://www.josip-pojatina.com/en/how-to-install-nvidia-driver-on-ubuntu-18-04-lts/

or

https://www.performatune.com/en/how-to-install-nvidia-driver-on-ubuntu-18-04-lts/

 

Although you can find more info about CUDA Toolkit installation at the following page:

https://docs.nvidia.com/cuda/cuda-installation-guide-linux/

there are a few important steps that are not mentioned there.

For that reason I want to further clarify installation process.

#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.

#Post-installation Actions
#Mandatory Actions
#Environment Setup
The PATH variable needs to include /usr/local/cuda-10.1/bin and /usr/local/cuda-10.1/NsightCompute-<tool-version>. <tool-version> refers to the version of Nsight Compute that ships with the CUDA toolkit, e.g. 2019.1.

To add this path to the PATH variable:

$ export PATH=/usr/local/cuda-10.1/bin:/usr/local/cuda-10.1/NsightCompute-2019.1${PATH:+:${PATH}}
