Which block/warp/thread breaks during Nsight debugging? Of the thousands of active threads, which do

[mods: sorry, I didn’t see a forum dedicated to Nsight. Can this be moved there?]

This is a basic question, but when Nsight hits a breakpoint, which actual thread is it?
It looks like the data is always from thread0 of block0?

Is there a way to probe the data in a different block/warp/thread? And more specifically, is it possible to probe into two warps that follow different branches?



All warps hit the breakpoint. However, only the selected warp is stepped when you are trying to step through code. I suggest you look at tutorial videos available on this site. They are immensely helpful.
