By the way, the numbers are for simple tests and are correct, as for that
segfault in the last test, this may have been an error owned by me.
But I don't know yet, I guess I must look at my old code agai

Hi many thanks for the effort.
Sorry for the late reply. In desperation, by now I have tried to switch my code
to openmp entirely and compile it with clang... But openacc has more
parallelization levels (

Hi thanks for the fast reply. Unfortunately none of these works...
(yes, putting in the -fno-math-errno option also raises this error, even if i
put it into -offload...
even if i try -foffload= -fno-math

how do I do that? -malias this is not a compiler option that is listed.

then I can define functions in a #pragma omp target

In my view, not only the new command is important, but also things like printf,
