For my Summer of Code project I've been rewriting GDAL's warping core
to run on the GPU via OpenCL. It's not fully tested yet, but I here's
what I have:

Feel free to play with it and tell me how it goes. If you find any
problems, please email me a helpful bug report with sample imagery and
the command you're using. It should work with the cubic, cubicspline,
& lanzcos resampling methods. The makefile is currently set up for
Mac, I'm not sure how to do it for linux/windows, and I don't have a
machine to test that on. If you get something working, please send it
my way.
I've been able to warp some basic, small, imagery with almost
identical results to the regular warper. The only difference is around
the raster's edges, where I believe the OpenCL code does a better job.
