CUDA-GDB is a debugger NVIDIA built by extending GDB, letting you debug host code and CUDA kernel code running on the GPU together. You can set breakpoints inside kernels, switch between threads, blocks, and warps, and inspect device memory and registers. It is used from the command line on Linux and underlies the Nsight family of graphical debuggers.
