I don't have CUDA experience so can't comment on this specifically. On the OSG side the setReleaseContextAtEndOfFrameHint() is only useful in when you have a single graphics context and are running your application SingleThreaded. There will be other ways to integrate CUDA rather than via the main loop. You should be able to create a custom GraphicsOperation and attach this to a GraphicsWidnow or Camera draw callback to invoke the CUDA side from within a thread that has the graphics context current.
