Introduction to Real-Time Linux: Unleashing Deterministic Computing

In 22.04, Canonical announced a beta version of the Ubuntu kernel with the PREEMPT_RT patchset integrated. The new real-time kernel serves extreme latency-dependent use cases and provides deterministic response times to service events. By meeting stringent preemption specifications, real-time is suitable across a broad range of verticals, from telco applications to dedicated devices in industrial automation and robotics.

But does a real-time kernel necessarily result in optimized performance? And what would be the consequences of missing a deadline? If you are a Linux kernel enthusiast or just getting started with real-time systems and want to learn more about PREEMPT_RT, this webinar is for you.

This webinar will provide a broad overview of the target use cases and real-time applications. Starting with the building blocks, we will learn:

- What is a real-time system?
- What are the use cases of real-time across market segments?
- What is the role of the PREEMPT_RT patchset?
- How would one know if a low-latency kernel is acceptable over PREEMPT_RT?

Real-time computing plays a crucial role in industries such as aerospace, automotive, industrial automation, robotics, and telecommunications. It demands precise and deterministic timing to meet stringent deadlines and ensure timely responses. That's where Real-Time Linux shines.
