Real-time scheduling is one of the most important concepts in Linux systems programming, embedded development, robotics, industrial automation, and performance-critical applications. Understanding how the Linux scheduler makes decisions can be the difference between predictable behavior and missed deadlines.

In this course, you will gain a comprehensive understanding of Linux real-time scheduling policies, with an in-depth focus on SCHED_FIFO, SCHED_RR, and SCHED_DEADLINE. Rather than simply covering the theory, the course explains how these scheduling policies behave in real systems, how the scheduler selects tasks for execution, and how different policies impact determinism, responsiveness, and deadline guarantees.

Throughout the course, you will learn:

How SCHED_FIFO works and its priority-driven execution model

How SCHED_RR extends FIFO with time slicing and round-robin scheduling

How SCHED_DEADLINE uses the Earliest Deadline First (EDF) algorithm and bandwidth reservation

Practical examples and experiments demonstrating scheduling behavior

C/C++ applications examples to demonstrate the different scheduling policies

Common pitfalls and best practices when developing real-time Linux applications

By the end of this course, you will be able to confidently configure, analyze, and troubleshoot Linux real-time scheduling policies and understand when to use SCHED_FIFO, SCHED_RR, or SCHED_DEADLINE to meet the requirements of your application.

Whether you are a Linux developer, embedded engineer, robotics developer, systems programmer, or operating systems enthusiast, this course will provide the practical knowledge needed to work effectively with Linux real-time scheduling.

Who This Course Is For

• Embedded systems engineers and developers
• Linux system programmers
• Robotics and automation developers
• Anyone interested in low-latency and deterministic systems

Requirements

• Basic knowledge of Linux commands and shell scripting
• Some C or C++ programming experience
• A Linux development environment (e.g., Ubuntu, Debian, or similar)

Why Take This Course

Linux is everywhere, but standard Linux is not deterministic. 
By understanding how to configure and program a real-time Linux system, you’ll unlock the ability to build responsive, reliable, and time-critical software for any industry.
