Hi Max, I've done some test using OpenCL in the context of the Faust project (http://faust.grame.fr/). Up to now results are not really good, and I guess CUDA/OpenCL will be usable only in specific cases. I'll probably now test if directly using CUDA would give some benefit. Maybe we can share some ideas?
