Intel® Advisor GPU Analysis
Intel Advisor has two features that can help you analyze the
performance of your application running on a GPU:
- Offload Modeling identifies kernels in your CPU-based code and predicts their performance when run on a GPU. It also helps you explore different GPU configurations for GPUs that do not exist yet.
- GPU Roofline Insights helps you see how your application is performing when compared to the limitations of your GPU.
Prerequisites
: To use Intel Advisor, first set up the Intel Advisor
environment variables:- On Linux*:source <install-dir>/advisor-vars.sh
- On Windows*:<install-dir>/advisor-vars.bat
The rest of this chapter covers the two features introduced above,
and a detailed recipe on using GPU Roofline Insights to analyze and
optimize memory-bound applications.
