How did you compile the code? GCC and Clang both target baseline 
x64, to use features like AVX2 you have to enable them, that of 
course means that not all CPUs will be able to run the code, 
though it will run faster on those that do.

I'd say this should include ARM as well, but there's one D 
compiler that doesn't support it so...
