<div>It's really similar to a binary search tree. Within each account, it is Shares / Usage to calculate the Level FS. See
<a class="x_moz-txt-link-freetext" href="https://slurm.schedmd.com/SUG14/fair_tree.pdf">
https://slurm.schedmd.com/SUG14/fair_tree.pdf</a> has more details, starting at page 34 or so. It even has an "animation".<br>

I've read the manual and I re-read the other link. What they boil down to is Fair Share is calculated based on a recondite "rooted plane tree", which I do not have the background in discrete math to understand.</div>

I'm hoping someone can explain it so my little kernel can understand.<br>
