Trying to understand the connection between these two concepts, after reading this page: Rendezvous — PyTorch 1.9.0 documentation 4
Do we need this min/max if I already know the exact number machines under my control?
Let us say I have two dedicated machines that I want to use for training. That means I want world_size=2.  Then both min and max should be exactly 2 for the intended allocation, right?   In what kind of scenario one would want to set min/max differently to take advantage of this flexibility?
