No idea, but I do know that the PGI group has had a working CUDA Fortran compiler since 2013:

One could take one's Fortran code and simply recompile it with their compiler to run on the Nvidia GPU's. The compiler would perform automatic parallelization. Wild stuff.

I'm aware of that, it's the main GPU compiler I'm using currently. But I have to say, PGI only has limited resources and it would be very cool if there'd be a second player in town, especially if it's one of the big five.

Btw. I'm working on something that's geared towards pretty much exactly what you're talking about. My stretch goal is fully automatic GPU parallelization for data parallel Fortran code [1].
