That sounds like a neat hack, but could you please say a bit more...

How are you measuring performance?  Packets per second?  Cycles per packet?  
(cycles of the main CPU)

Most GPU cards don't have network hardware.  How are the packets getting 
to/from the internet and your code running on the GPU?

ntpd, or at least the reference implementation, is single threaded.  What are 
you doing with the other 99 cores on the GPU?

These are my opinions, not necessarily my employer's.  I hate spam.
