I watch the running situation use command ‘watch -n 1 nvidia-smi’，but I found that, the first card run normal, are when it run over, the second card started to run, so did 3th and 4th.But I don’t set four threads or processes. Why this happens? Does profile with cuda run all gpu cards to profiler, and only show one card’s profile result?
I am confused, thanks a lot if you can give me addvisions or give me some useful links.
May a good day!
