Yes, that concept of rank tripped me up. The "count of user associations that start at root" you mean? Do you mean all associations across all accounts or just the account being examined? Then you say "final fairshare factor similar to (rank-- / user_assoc_count)".
Wouldn't that equal 1? I'm clearly not understanding something fundamental.<br>

The basic idea is to set rank equal to the count of user associations then start at root:<br>
* Calculate Level Fairshare for the subtree's children<br>
* Sort children of the subtree<br>
* Visit the children in descending order:<br>
- If user, assign a final fairshare factor similar to (rank-- / user_assoc_count)<br>
- If account, descend to account<br>

I'm not talking about the Level Fair Share. That's easy to compute. I'm talking about Fair Share -- what sshare prints out on the rightmost side.</div>

<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_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>
