Konstantin,

The OpenCL integration is currently only used to accelerate the warp engine
(gdalwarp, etc).  There are some other areas of GDAL that could potentially
use OpenCL facilities too but no further work has been done.

I will note that for the expensive resamplers Seth has seen very substantial
speedups.  The preliminary plan for Seth's project is documented at:

   http://trac.osgeo.org/gdal/wiki/OpenCLIntegration

We really need to rework that to include "findings and current status".

Best regards,
