I am trying to use Intel oneAPI advisor beta to do a GPU offloading analysis (via analyze.py and collect.py). I have the problem that all non offloaded regions show Cannot be modelled: No Execution Count.

Furthermore I get the warning

advixe: Warning: A symbol file is not found. The call stack passing through `...../programm.out' module may be incorrect.

I've already tried the troubleshooting described here and here. Moreover I tried using a programm with larger runtime.

I compiled with the compiler flags (according to this) (notice that debugging information is turned on):

-O2 -std=c++11 -fopenmp -g -no-ipo -debug inline-debug-info

I am using Intel(R) Advisor 2021.1 beta07 (build 606302), and Intel(R) C Intel(R) 64 Compiler for applications running on Intel(R) 64, Version 2021.1 Beta Build 202006. The program uses OpenMP.

What could I do to solve this problem?

The problem occurred because the program had too large a workload / the memory of the machine was not sufficient.
