The loop trip count should be set per task but libomptarget has no notion of tasks, so we ended up engaging the host runtime (libomp) to store per-task information. Although it involves more work, I still believe that will be a more elegant solution.


I don't see a big problems here. You can store the mapper data per task using thread id from libomp, as we do it for tripcount. We can use the same solution for mappers.
