I see under the "Target Accelerators" when I select the NVIDIA option the ability to select both the toolkit and CC versions. Appears 12.5 doesn't yet include the 4.2 toolkit version. I've left both of these on auto/default, assume that is fine. Also I had the CUDA toolkits installed separately and there are Windows environmental variables from those installations. I assume PVF doesn't get confused by these separate installations.

Final question: I have two GPUs installed, a Fermi (GTX 580) and a Kepler (GTX 680). I know PGI doesn't yet support the Kepler GPUs but will the compiler pick up the Fermi when it builds and then when I execute?

Correct, CUDA 4.2 will be added to the 12.6 release.

There were some problems with earlier release but 12.5 should be fine. Granted I personally only test on Linux so there may be Windows issues I'm not aware of.

Thanks Mat, seems to be starting execution with 12.5 while failing using 12.4. But there are problems with the execution that I'll have to identify and will post separately.
