collect=roofline --profile-gpu

Usage

Important

GPU profiling is applicable only to Intel® Processor Graphics.

This option may affect the performance of your application on the CPU side. Increasing the wait time between samples can decrease collection overhead.

Example

Run a Survey analysis. Enable GPU profiling and increase the GPU sampling interval to 3 ms.

advisor --collect=survey --profile-gpu --gpu-sampling-interval=3 --project-dir=./advi_results -- ./myApplication
