Real-time Ubuntu use cases

Industrial settings

PLCs in assembly lines must deliver and process data in real-time to ensure system integrity and continuous production.

Telco

Real-time Ubuntu brings ultra-low latency and enhanced security capabilities to telco workloads and the critical infrastructure they run on.

Healthcare robotics

From autonomous mobile robots to life-support medical equipment, healthcare systems must complete tasks within specified deadlines.

Automotive

Automotive manufacturers are increasingly reliant on real-time Linux for infotainment systems, HMIs and latency-sensitive scenarios.

What is Real-time Ubuntu?

Canonical and Intel collaborate to deliver real-time Ubuntu on 12th Gen Intel® Core™ processors with TSN and TCC Support. Explore how real-time Ubuntu benefits the IoT customers and market as a whole.

Getting started

With the PREEMPT_RT patches being fully upstreamed, the real-time kernel is freely available for everyone from the 26.04 release onwards. Simply use the command: 

sudo apt install ubuntu-realtime

Need earlier versions?

All previous releases of the real-time kernel are available via Ubuntu Pro, Canonical's enterprise security and compliance subscription. Ubuntu Pro is free for personal and small scale commercial use in up to 5 machines.

With an Ubuntu Pro subscription, launching the real-time kernel is as easy as:

pro attach
pro enable realtime-kernel

Discover Ubuntu Pro

Run Real-time Ubuntu on Intel hardware

Optimized Real-time Ubuntu is available on 12th Gen Intel® Core™ processors. Coupled with Intel® Time Coordinated Computing (Intel® TCC) and Time Sensitive Networking (IEEE TSN), the real-time kernel delivers industrial-grade performance to meet stringent latency requirements:

Intel-optimized Real-time Ubuntu is available on Intel SoCs via Ubuntu Pro: 

pro attach
pro enable realtime-kernel --variant=intel-iotg

Run Real-time Ubuntu on Raspberry Pi

Based on the upstream v6.8 kernel, the 24.04 release of Real-time Ubuntu includes optimized support for Raspberry Pi hardware. Discover the possibilities of optimized real-time compute with enhanced performance on Raspberry Pi 4 and 5: 

pro attach
pro enable realtime-kernel --variant=raspi
