The lackluster support of OpenCL is likely the biggest thing standing in the way of software transitioning from CUDA to OpenCL on OS X. Apple needs to stop just talking big about OpenCL and offer the aggressive support it needs to actually compete with CUDA. It’s a sad irony that Apple invented OpenCL only to see it better supported on competing platforms and that dealing with Apple to resolve problems is “unpleasant” because the company is so opaque. It is safe to say that the breakneck pace with which Final Cut Pro X 10.1 got its excellent dual GPU support wouldn’t have been possible if it wasn’t an Apple product with two teams in shouting distance of each other. Next time you read that some software isn’t optimized for the new Mac Pro or OpenCL on OS X, think twice before sticking the pitchfork in the developer—it might be Apple slowing it down.

I have been reading thru all the MacPro reviews and wondering where the The Foundry are with OpenCL. They where mentioned in by Apple in the WWDC keynote. But that doesn't mean they are getting help from Apple. I hear that an OpenCL version of Nuke is coming but how long and how good will it be. Having a GPU just for Nuke would be great but only if it works. In this same review a developer asks Apple to make Mac OS X versions of OpenCL comparable to the Linux and Windows versions.

The OS X version Mari is said to be pretty good, I hope it is going well with the Nuke code.
