DGX OS 8 / Ubuntu 26.04

About DGX OS 8

NVIDIA DGX OS provides a custom NVIDIA BaseOS distribution based on Ubuntu with optimizations and additional software for DGX supercomputers, featuring a fully tested, stable environment for AI and machine learning workloads.

NVIDIA DGX™ systems are shipped preinstalled with DGX OS to provide a turnkey solution for running AI and analytics workloads. Initial system configuration is deferred to a setup wizard that runs after the first boot. The setup wizard offers a fast onboarding experience for DGX users.

The DGX OS installer is released as an ISO image for reimaging a DGX system. It deploys Ubuntu and the BaseOS software for DGX, which consists of drivers, additional tools, and configurations specific to the DGX platform.

You also have the option to install the BaseOS software on Ubuntu 26.04 while still benefiting from the advanced DGX features. This installation method supports more flexibility, such as custom partition schemes. Cluster deployments also benefit from this installation method by taking advantage of Ubuntu’s standardized, automated, and non-interactive installation process.
