@rgillen, why did you copy/paste your post from a year ago as a new thread here?
After a year, do you really have the exact same question? You didn’t provide any additional info (GPU, OpenCL driver, what you’ve tried, etc.). So it’s unclear why you think this post should generate anything useful.
Please see The Forum Posting Guidelines for tips on composing a post that is more likely to net you the information you’re looking for.
Have you tried any of the solutions in the archives for folks having exactly the same problem?
