Within OpenCL the GPU does the parallel thing for you. There is a blog post on that [0]. According to that you have to set "export multiple images in parallel" to 1. BTW this setting was removed sometime ago from the GUI or I can't find it anymore. Modern GPUs are ways faster than CPUs usally. Only nvidia cards/drivers have a problem on profiled denoise as discussed on IRC yesterday. In general nvidia cards seem to have a bad OpenCL performance if you look at [1]. And still my low budget passive cooled GT 640 outperforms my i7-2600 most of the times. Hope that helps a bit.
