How to Get The Number of Page Faults?

Hello,
Is there any way to get the numbers of CPU page faults and GPU page faults? I looked into nvprof but don’t find one related metric/event, and I also tried nsight by
"nsys profile
–cuda-um-gpu-page-faults=true
–cuda-um-cpu-page-faults=true
my_application
", but the two options are not recognized, although they are presented in nsight’s documentation. Is there any way to get the numbers of CPU and GPU page faults separately? Also, I see \usr\bin\time can report a page fault number, is it the sum of CPU and GPU page fault numbers?

Hi,

We are checking this internally.
Will share more information with you later.

Thanks.

Hi,

The page fault profiling is a desktop feature.
It doesn’t support the Jetson devices.

Thanks.
