Microseconds Matter: Benchmarking Thread Synchronization - Gautham Ponnu, The MathWorks
Tuesday May 19, 2026 3:05pm - 3:45pm CDT
208A+B (Level Two)
This talk aims to analyze the performance of most common Linux synchronization primitives under PREEMPT_RT, comparing their behavior across a range of workloads. We’ll explore how each primitive scales with thread count, handles contention, and impacts determinism. Expect graphs, latency histograms, and a few surprises. If you’re building real-time systems or tuning performance, this session will help you make smarter, faster, and safer decisions.
