Optimizing HPC Code with Roofline Analysis

In this special guest feature, James Reinders describes why roofline estimation is a great tool for code optimization in HPC. “As a long-time teacher of optimization techniques, I can confidently say that Roofline analysis is a must-have for anyone optimizing for performance. This has not always been the case. As I will explain, today it is an important technique to draw upon when doing performance optimization.”
