Hi, I'm wondering why cuda-double flavor had worse precision and performance than cuda-single did.

I wouldn't worry too much about GPU issues, because they will bring an interesting speed-up only in specific cases. If your hardware is a bit outdated, MPI and OpenMP will do a pretty good job already.
