If Altera's example also fails on your device, the problem is somewhere else. The design readme says that it only works with Quartus/AOC v16.1 and a compatible BSP. From what I remember, you are using older versions and that is probably why it doesn't work for you.

You should take this fact into consideration that if your kernel is very short, the overhead of going back to the host after kernel execution finishes, and relaunching it, might be higher than the kernel execution itself.
