Debugging and printf in kernel

[Robert_Crovella]

@boxerab

Is there printf capabilities in CUDA ?

Yes, there is in-kernel printf available.

@boxerab

More generally, what is the best way of debugging a kernel ?

I generally recommend to start with proper CUDA error checking and use of compute-sanitizer as I outlined here. More generally, this online training series covers debug in some detail, in session 12.
