Re: [Gegl-developer] Building opencl branch

[Victor Oliveira <victormatheus gmail com>]

For now, I've been using the gegl op tool in gimp to test gegl
operations with OpenCL.
But it shouldn't be hard to create a simple filter using the gegl API
and test performance.

If you want to enable OpenCL, just set the GEGL_USE_OPENCL env variable [1].

Also, if you build gegl with --enable-debug, you can set
GEGL_DEBUG=opencl and get some messages about what's going on [2].
Take care that these messages change execution time.
