WebIt is OK to break out of a loop nested inside an OpenMP loop. Branching out of an OpenMP loop to call an error-handler is allowed, but if this should happen, OpenMP will automatically terminate the threads that are processing the rest of the loop. Since OpenMP 3.0 it is possible to have nested parallel loops, and more generally, nested parallel ...
