Migration path from OpenGL/Cg app to running on Telsa...

Hi, we have an app that uses OpenGL and Cg, and want to run it in Amazon EC2 using their Tesla hardware (http://aws.amazon.com/hpc-applications/).

Will the app run on these cards (I’ve read answer is ‘no’), so if not, what is the migration path, is there any compatibility libs, or conversion scripts people use to go to CUDA/OpenCL (or other?), or does the app simply need to be ported/rewritten by hand.

Thanks
