My own opinion regarding this discussion is that first it should be
demonstrated that CPU consumption is an actual ZFS bottleneck (and
will continue to be in the near future) before looking at ways to
eliminate that bottleneck.
The current instantiation of GPUs in computer hardware is a poor
design and quite wasteful of resources. That is a reason why I refuse
to consider depending on GPUs in my own software. See my reasoning
here:
"http://www.graphicsmagick.org/FAQ.html#are-there-any-plans-to-use-opencl-or-cuda-to-use-a-gpu";
There is every reason to believe that Intel (and perhaps AMD) will
introduce updated CPUs which provide the arithmetic benefits of GPUs
within their native instruction sets, and with little increase in cost
and power consumption. This is in addition to the explosion in the
number of computing cores per socket.
Except for very specific computing situations, GPU add-on hardware is
a very poor architecture going forward into the future.
