Hi gdal-devs, 
I have a question, if there is some way to use gdalwarp in a clustering system 
(e.g., Sparks) or with GPU to speed up the process? My task involves 
re-projection and re-sampling of hundreds of high-resolution images. Any ideas 
to make use of Sparks or GPU is welcomed. Thank you. 
Simon
