Hi,
what benefit/improvement would the OpenCL integration bring to GDAL?
Additional functionality or a speedup of existing functions? Probably only
operations on images and/or rasters are supported; reprojection/warping and
filtering would be good candidates, right? What concrete operations would be
supported?
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,
