It looks like there are two profilers at this point, nsys and ncu. Which should I be using? What are the benefits of each? I’m on CUDA 11.4, and I don’t expect to upgrade to 12.x any time soon. If it matters, I’ll be profiling within a docker container, so I do need a way to generate profile data via the command line. I can view via GUI outside the container. I’ll be profiling on both x86-64 and aarch64 (Xavier Orin).
You would generally start with nsight systems (nsys). When you have narrowed your focus down to the behavior of a kernel or kernels, you would shift to nsight compute (ncu). here is an introductory ncu blog. here is a relatively basic nsys blog.
