Nvprof and OpenMP does not work

I can’t seem to get nvprof to return any openmp statistics. I just get

Warning: No profile data collected.

This is with openmp 4.5 directives for gpu off loading as well as with simple older openmp directives for cpu threads. I’m using pgcc 20.7-0 and nvprof 10.2.89

nvprof successfully profiles pure cuda code and python linked to cuda

Am I missing a something? I’d expect ‘nvprof program.e’ to return something.
thanks
