Roofline Resources for Intel® Advisor Users

Published: 07/13/2020  

Last Updated: 03/31/2021

Intel® Advisor provides design tools to help ensure your C/C++, Fortran, Data Parallel C++, OpenMP*, and OpenCL™ native/managed applications realize full performance potential on modern processors: Vectorization and Code Insights, CPU Roofline / Memory Insights, Threading, Offload Modeling, GPU Roofline Insights, and Flow Graph Analyzer.

Intel Advisor is available for download as a standalone installation and as part of Intel® oneAPI Base Toolkit.

CPU Roofline / Memory Insights and GPU Roofline Insights features visualize actual performance against hardware-imposed performance ceilings (rooflines). They provide insights into where the bottlenecks are, which loops are worth optimizing for performance, what are the likely causes of bottlenecks and what should be the next optimization steps.
