<p>Hi,</p>
<p><br>
</p>
<p>I am new to slurm and I'm having some issues scheduling correctly <br>
</p>
<p>my tasks. <br>
</p>
<p>I have a very small cluster(if it even could be called a cluster) with only <br>
</p>
<p>one node for the moment; the node is a dual Xeon with 14 cores/socket, <br>
</p>
<p>hyper-threaded and 256GB of memory, running CentOS 7.3.</p>
<p><br>
</p>
<p>I have a single threaded process which I would like to run <br>
</p>
<p>over a series of input files(around 370). I have found that the packed <br>
</p>
<p>jobs scenario fits with what I'm trying to achieve. So I would like to <br>
</p>
<p>run 50 instances of my process at the same time over different input files.</p>
<p><br>
</p>
<p>The moment I schedule my script I can see that there are 50 instances of <br>
</p>
<p>my process started and running but just a bit afterwards only 5 or so of them <br>
</p>
<p>I can see running - so I only get full load for the first 50 instances and not
<br>
</p>
<p>afterwards.<br>
</p>
<p><br>
</p>
<p>In the slurmctld.log I can see this type of messages:</p>
<p>"<span>[2017-11-06T11:56:39.228] job_step_signal step 1489.107 not found</span>"</p>
<p>and in my script output file I can see:</p>
<p>"<span>srun: Job step creation temporarily disabled, retrying</span>"</p>
<p><br>
</p>
<p>At this point I'm sifting through documentation and online info trying to figure
<br>
</p>
<p>out what is going on. I have attached my slurmctld log file, slurm config file, script and</p>
<p>the output I get from sinfo, stat and the likes.</p>
<p><br>
</p>
<p>Any pointers on how to attack this problem would be much appreciated.</p>
<p><br>
</p>
<p>Thank you<br>
</p>
<p><br>
