double's on the GTX 285

I’ve tried to move a simple test program that sums up numbers to use double numbers instead of floats. I don’t get any compile errors, but the kernel no longer seems to do anything. I also get no errors.

I assume the card doesn’t support this on my Mac, but I’m surprised I don’t get any kind of an error.

Can someone explain?

compile with -arch sm_13

That did it. It works great.
