I've been intending for a while to work on either CUDA or OpenCL with GDAL & GRASS. I applied to do this for the Google Summer of Code, but wasn't accepted this past summer. I'll probably work on it someday just to make sure my thesis work gets finished within budget. However, I'm mostly interest

2009-11-18 Thread Shaun Kolomeitz
I've heard a lot about the power of NVidia CUDA and am curious about ways in which we could leverage off this to increase the performance of 1) Image Mosaics 2) Translates and 3) Image Reading/rendering (especially highly compressed images). I also see that there is pyCUDA as well. Both of which I
