<div class="PlainText">Hello,<br>
<br>
Our cluster is very rarely fully utilized, often only a handful of jobs <br>
are running.<br>
This has the effect that the first couple nodes get used a whole lot <br>
more frequently than the ones further near the end of the list.<br>
<br>
This is primarily a problem because of the SSDs in the nodes. They <br>
already show a significant difference in their wear level between the <br>
first couple and all the remaining nodes.<br>
<br>
Is there some way to nicely assign jobs to nodes such that all nodes get <br>
roughly equal amounts of jobs/work?<br>
I looked through possible options to the SelectType, but nothing looks <br>
like it does anything like that.<br>
