Hello Everyone,
I have a trouble with opencl. The button in Compositing _ Cooking in not activ. I could not resolve this problem while browsing the houdini forum. I tried input in ~/houdinixxx/houdini.env variables like this:
HOUDINI_OCL_DEVICETYPE=GPU
HOUDINI_OCL_DEVICENUMBER=0
but without effect.
Can you help me, please?

GPU compositing has been removed as a feature, indefinitely. FWIW, it didn't use OpenCL, just regular OpenGL.
