Intel® Advisor provides design tools to help ensure your Fortran, C and C++ native/managed applications realize full performance potential on modern processors: Vectorization Advisor, Roofline, Threading Advisor, Offload Advisor, and Flow Graph Analyzer.
Roofline analysis visualizes actual performance against hardware-imposed performance ceilings (rooflines). It provides 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.
Learn what the Roofline is and how it works using the following resources:
Start taking advantage of the power and flexibility of the Roofline Analysis of the Intel Advisor using the following resources:
Intel Advisor provides several advance features of the Roofline to help you visualize actual performance against hardware-imposed performance ceilings, as well as determine the main limiting factor (memory bandwidth or compute capacity), thereby providing an ideal roadmap of potential optimization steps.
Start with the User Guide, which provides an overview of all Roofline analysis capabilities available in the Intel Advisor:
