Does that mean that we can never have OpenMP + joblib? I though using OpenMP on supported platforms would be possible in the future. Would it be possible to enable OpenMP but then die if someone attempted to do joblib parallelism, e.g. let the user choose what they want?
Or do you think that would be to complicated?
