It's probably better to do a 4 vector transpose here or invert the MMA inputs. That way you can write vectors at a time instead of scalar elements.

How come aoffset5 - 8 are not updated here? Could this be the reason it only works for multiples of 8?

Is it possible for CMAKE_SYSTEM_PROCESSOR to match both ppc64 and ppc64le?
