Time cost of tutorials
Created by: liwt31
I tried to run the first tutorial example transverse field Ising model and found it took the computer (Xeon E5-2630 with enough memory) 10 min to finish the calculation in serial mode. If the tutorial example really needs 10 min time, I think it'll be nice to point it out in the tutorial because a minimal working example usually does not take so much time. If something of my compilation or computer went wrong, it'll also be helpful for me to know that the example should take less than 1 min. So, my suggestion is to add some comment on running time in the tutorial. I think it's beneficial for helping new users know about the program.
