GPGPU related topic for Master's Dissertation


In a couple of months I’m about to start my Masters Dissertation and I’m looking for some ideas. Since I have some background on GPGPU (mainly OpenCL and a little Cuda knowledge as well), I’m looking for something related with these technologies. Can you provide me some ideas?
Looking in a more practical perspective, what could be done for OpenCL/Cuda, what needs to be done? Where can I eventually provide some contribute?

Thanks in advance!
