Recompiling is only useful if you're running your code on the Phi
itself (as Stu does) and thus can cope with the tiny amount of RAM it
has.

However, the other model being pushed is as an offload device (like
GPGPU) as you can see here:

It's the offloading use (in free or proprietary applications) that I'm
curious about.

cheers!
