gpu-sampling-interval (Beta)

Specify time interval, in milliseconds, between GPU samples during Survey analysis.


is the number from 0.1 to 10 milliseconds between GPU samples.
Actions Modified
=survey --profile-gpu
=roofline --profile-gpu
This option may affect the performance of your application on the CPU side. Increasing the wait time between samples can decrease collection overhead.
Run a Survey analysis. Enable GPU profiling and increase the GPU sampling interval to 3 ms.

Product and Performance Information


Intel's compilers may or may not optimize to the same degree for non-Intel microprocessors for optimizations that are not unique to Intel microprocessors. These optimizations include SSE2, SSE3, and SSSE3 instruction sets and other optimizations. Intel does not guarantee the availability, functionality, or effectiveness of any optimization on microprocessors not manufactured by Intel. Microprocessor-dependent optimizations in this product are intended for use with Intel microprocessors. Certain optimizations not specific to Intel microarchitecture are reserved for Intel microprocessors.
