Conquering Noise with Hardware Counters on HPC Systems

Explore a seminar on conquering noise with hardware counters in HPC systems, presented by Ahmad Tarraf from the Technical University of Darmstadt. Delve into the challenges of examining application scaling behavior and identifying performance bottlenecks in complex systems. Learn about the impact of noise on application runtime and hardware counters, and discover techniques for selecting appropriate counters for performance modeling. Gain insights from a noise analysis conducted on various hardware counters across five systems using different applications and noise patterns. Understand how counters are categorized based on their noise resilience. Benefit from Dr. Tarraf's expertise in high-performance computing, efficient file and storage systems, behavioral modeling, and machine learning. Access the presentation slides and learn about the speaker's background in mechatronics engineering, formal verification, and involvement in EuroHPC projects.
