I think that's the expected behavior in OpenACC. Basically, unless pointers have explicit data clauses with subarray arguments, the compiler is supposed to treat those pointers as "scalars" and not remap the contents of the pointer. Chung-Lin, maybe this issue with allocatable data along with a different void will persuade the OpenACC technical committee update the implicit data mapping behavior of pointers.

So, please first get this working with firstprivate on > allocatables and only then start to play with reductions. I agree something like that would be better. Is OpenMP supposed to implicitly map the allocated data on the accelerator too? Cesar
