<div>Hi David,</div>

<div>What does:</div>
<div><br>
</div>
<div>scontrol show node orange01</div>
<div>scontrol show node orange02</div>
<div><br>
</div>
<div dir="ltr">show? Just to see if there's a default node weight hanging around, and if your weight changes have been picked up.<br>

<p style="margin-top:0px;margin-bottom:0px">I'm experimenting with node weights and I'm very puzzled by what I see. Looking at the documentation I gathered that jobs will be allocated to the nodes with the lowest weight which satisfies their requirements. I
have 3 nodes in a partition and I have defined the nodes like so..</p>

<p style="margin-top:0px;margin-bottom:0px"></p>
<div>NodeName=orange01 Procs=48 Sockets=8 CoresPerSocket=6 ThreadsPerCore=1 RealMemory=1018990 State=UNKNOWN Weight=50</div>
<div>NodeName=orange[02-03] Procs=48 Sockets=8 CoresPerSocket=6 ThreadsPerCore=1 RealMemory=1018990 State=UNKNOWN</div>
<br>
<p></p>
<p style="margin-top:0px;margin-bottom:0px">So, given that the default weight is 1 I would expect jobs to be allocated to orange02 and orange03 first. I find, however that my test job is always allocated to orange01 with the higher weight. Have I overlooked
something? I would appreciate your advice, please.</p>
