Correct.

In order to execute code on the GPU instead of the CPU, you actually need to
have code that the GPU understands and that is written in a way the such that

And sadly, there is no magic wand that takes existing code and just makes it
work there.  Just how you can't just execute your (x86) Windows binaries on
your (old PPC) Mac etc pp.

Can you quote what they state, please?
