ECP23 Tutorial Video
The Roofline performance model offers an insightful and intuitive method for extracting the key execution characteristics of HPC applications and comparing them against the performance bounds of modern CPUs and GPUs. Its ability to abstract the complexity of memory hierarchies and identify the most profitable optimization techniques have made Roofline-based analysis increasingly popular in the HPC community. The tutorial will introduce the fundamental aspects behind different Roofline modeling principles as well as providing several practical use case scenarios that highlight their efficacy for application optimization on CPUs and GPUs.
