Advisor - Limit "projection" analysis only to certain files or functions

offloadgpu

Hi, I'm interested in limiting the "projection" analysis only to certain files or functions. I want to check the offload to GPU profitability for an application but I want suggestion based only on some files or loops and not on the whole codebase.

I've tried using the collection control APIs  adding

#include <ittnotify.h>
__itt_resume();
some_code(),
__itt_pause();

rebuilding the app, and firstly when I launch, started paused, the "survey" analysis "collection resumed" and "collection pause" are printed several times, meaning that the markers are working. Then it seems that the collection control APIs are not working for the "projection" analysis, since the suggested functions for offloading are the almost the same than the ones without the control APIs.  Am I doing something wrong? Is there a better way to limit the "projection" analysis only on some files? Thanks in advance

You don't need to use ITT API here. I'd recommend to use mark-up feature instead:

 

advisor --collect=projection --select=foo.cpp:34,bar.cpp:192 --enforce-offload --project-dir=./advi_results
