Top-down Performance Analysis

Presented by

Florent Lebeau, Solutions Architect, Arm

About this talk

For Linux server and HPC applications, Top-Down performance analysis is a popular and effective optimization methodology. By categorizing subsets of CPU hardware events the approach highlights which portion of the CPU pipeline is starving, guiding the programmer towards relevant bottlenecks in a robust hierarchical manner. The latest version of our profiler in Arm Forge introduces configurable CPU metrics based on hardware events. In this webinar, Florent Lebeau, Solutions Architect from Arm, will demonstrate: • Basic and advanced usage of this feature for issue identification • How top-down performance analysis is applied to optimize using Arm Forge.
