Optimize application performance with CPU affinity

About this Learning Path

Who is this for?

This is an advanced topic for developers, performance engineers, and system administrators looking to fine-tune the performance of their workload on many-core Arm-based systems.

What will you learn?

Upon completion of this Learning Path, you will be able to:

• Pin threads to specific CPU cores using taskset and source code modifications
• Measure cache performance improvements from thread pinning using perf
• Evaluate performance trade-offs between throughput and latency consistency
• Implement CPU affinity strategies for co-located workloads

Prerequisites

Before starting, you will need the following:

• An Arm Linux system with four or more CPU cores
• Experience with multi-threaded programming in C++ and Python
• Understanding of build systems and computer architecture concepts
• Familiarity with Linux command-line tools
