I'm not sure what you mean by "if they have the permissions". I'm talking about someone who is specifically designated as "coordinator" of an account in slurm. With that designation, and no other admin level changes, I'm not aware that they can directly change
the priority of jobs associated with the account.</div>

If you're talking about additional permissions or admin levels...we're not looking into that as an option. We want to purely use the coordinator role to have them manipulate stuff.</div>

<p>If they have the permissions, you can just raise the priority of user B's jobs to be higher than whatever A's currently are. Then they will run next.</p>
<p>That will work if you are able to wait for some jobs to finish and you can 'skip the line' for the priority jobs.</p>
<p>If you need to preempt running jobs, that would take a bit more effort to set up, but is an alternative.</p>

I was asked to see if coordinators could do anything in this scenario:</div>
<div class="x_elementToProof" style="font-family:Calibri,Arial,Helvetica,sans-serif; font-size:12pt; color:rgb(0,0,0)">
<ul data-editing-info="{"orderedStyleType":1,"unorderedStyleType":1}">
<li style="list-style-type:disc">Within the account that they coordinated, User A submitted 1000s of jobs and left for the day.</li><li style="list-style-type:disc">Within the same account, User B wanted to run a few jobs really quickly. Once submitted, his jobs were of course behind User A's jobs.</li><li style="list-style-type:disc">The coordinator wanted to see the results of User B's runs.</li></ul>
<div>Reading the docs and doing some experiments, here is what I determined:</div>
<div>
<ul data-editing-info="{"orderedStyleType":1,"unorderedStyleType":1}">
<li style="list-style-type:disc">The coordinator could put a hold on all of User A's jobs in the pending queue. This won't affect any jobs User A has that aren't tied to the coordinated account.</li><li style="list-style-type:disc">With User A's jobs held, then User B's jobs would be next to run.</li><li style="list-style-type:disc">If the coordinator was particularly impatient, he could scancel User A's currently running jobs so that User B's jobs immediately started.</li><li style="list-style-type:disc">The coordinator would need to remember to release the held jobs, or put them in a uhold so that User A could release them eventually.</li></ul>
<div>It seems like the easiest way for the coordinator to elevate User B's jobs to the top of the queue would be if he could "scontrol top" those jobs. But my testing indicates that the coordinator doesn't have that permission. Is there some reason that a
coordinator can't use "scontrol top" to change the priority of jobs within the account that he coordinates?</div>
