Hi, I'm trying to evaluate the GFLOPs of my application in a constrained area of the code, thats only on a heavy function (>2sec of execution), using "ittnotify.h".
I've followed the configure your system guide and successful built with:
g++ -g -O3 -std=gnu++0x -I/opt/intel/oneapi/vtune/2022.4.0/sdk/include -L/opt/intel/oneapi/vtune/2022.4.0/sdk/lib64 source.cpp -o source.o -pthread -littnotify -ldl
I'm trying to execute the "Performance snapshot" analysis via CLI to get the number of GFLOPs, starting by paused with:
vtune -collect performance-snapshot -start-paused -finalization-mode=full -r ./result -- ./source.o
And then attempting to resume the analysis from code. Unfortunately it seems to not be able to find the "__itt_resume();" command, since it prints "EMON collector was started in PAUSE mode and never RESUMED". This is how I'm trying to use the library:
int main(int argc, char **argv) {
... some code ...
__itt_resume();
myFunction(1,2,3);
__itt_pause();
.... other code ...
return 0;
}
Does anyone know why this is not working? Thanks in advance!
