Parts of it for my application.  My desire wasn't to become a GMP
contributor, but a user.  That has changed now and I'm in "discovery
mode." :-)

Will check it out.  Some existing 128-bit and 256-bit GPU libraries have
exhibited order-of-magnitude greater performance due to the 200+ GPU
cores able to process data in parallel.
