About DGX OS 6

NVIDIA DGX OS provides a customized installation of Ubuntu Linux with system-specific optimizations and configurations, additional drivers, and diagnostic and monitoring tools. It provides a stable, fully-tested, and supported OS to run AI, machine learning, and analytics applications on DGX Supercomputers.

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 users a fast on-boarding experience for using DGX systems.

The DGX OS installer is released as an ISO image to reimage a DGX system. The additional software, the NVIDIA DGX Software Stack, that is included in DGX OS is provided as packages that are available from software repositories over the internet.

You also have the option to install the NVIDIA DGX Software Stack on a regular Ubuntu 22.04 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.
