<p class="MsoNormal"><span style="font-family:"Calibri Light",sans-serif">Hi all,<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-family:"Calibri Light",sans-serif"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-family:"Calibri Light",sans-serif">Wondering whether someone could help me with the following:<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-family:"Calibri Light",sans-serif"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-family:"Calibri Light",sans-serif">I am new and struggling a bit with some slurm concepts.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-family:"Calibri Light",sans-serif"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-family:"Calibri Light",sans-serif">We are running an old version: 17.02.11 soon upgrading to 18.X<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-family:"Calibri Light",sans-serif">On our slurm.conf "SelectType=select/cons_res"<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-family:"Calibri Light",sans-serif">https://slurm.schedmd.com/cpu_management.html#Step1<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-family:"Calibri Light",sans-serif"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-family:"Calibri Light",sans-serif">21x compute nodes * 32 cores = 672<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-family:"Calibri Light",sans-serif">partition=standard<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-family:"Calibri Light",sans-serif"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-family:"Calibri Light",sans-serif">User was submitting a job and requesting 168CPUs. Basically the job was getting allocated 6x nodes [5*32 + 1*8]. Which means that 5 nodes fully committed to this single job. If he submitted
4x jobs, one would go pending because each job “required” 6x nodes.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-family:"Calibri Light",sans-serif"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-family:"Calibri Light",sans-serif">Would it be possible to achieve, instead: 21x nodes providing 8x cores each, i.e., same total 168 and therefore still able to run the 4<sup>th</sup> job and maxing out the resources?
Would it mean specifying –minnodes=21?<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-family:"Calibri Light",sans-serif"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-family:"Calibri Light",sans-serif">Or it does not make any sense what I am saying?<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-family:"Calibri Light",sans-serif"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-family:"Calibri Light",sans-serif">Thanks in advance<o:p></o:p></span></p>
