    Kernel having nested loop vs loop calling kernel multiple times

    niravshah00

      Hi,

       

      I have three nested loops .

      Now the question is to have the nested loop in the kernel  so that each thread has the nested loop or to have the nested loop on host code and launching the kernel multiple time

      Which would yield better performance?

      FYI : its 3 nested FOR  loops and i have an option of putting them in the kernel or host code.
