If you dont set it to recommended setting, most likely the moon will leave earths orbit. change it to recommended setting and save the world from tidal catastrophe.
Yes the value recommends (nproc-4)

Then semmnu is 4192 ???
Here both node values are 4196 & 256, so which is the exact value to set on both nodes.?
