What do you use the debug the CUDA Program

Accelerated Computing CUDA CUDA Programming and Performance

Just want to know what kinds of tools you are using to debug the CUDA Program.

I tried to use Nsight to debug my CUDA Program on a single GPU Platform but it failed. I got the reason that the GPU is only for display or only for GDB, that means I cannot debug the CUDA program with Nsight using a single GPU platform.

So, do you turn off the X server and use the command line to debug the CUDA Program or you debug the CUDA Program remotely?

cuda-memcheck still works, and I use lots of printf when I suspect problems in some parts of the code.
