<p>So the node definition is separate from the partition definition.</p>
<p>You would need to define all the GPUs as part of the node.
Partitions do not have physical characteristics, but they do have
QOS capabilities that you may be able to use. You could also use a
job_submit lua script to reject jobs that request resources you do
not want used in a particular queue.<br>
</p>
<p>Both would take some research to find the best approach, but I
think those are the two options available that may do what you are
looking for.</p>

<div>Hi Community,</div>
<div>I was checking the documentation but could find clear
information on what I am trying to do.</div>
<div>Here at the university we have a large compute node with 3
classes of GPUs. Lets say the node's hostname is
"gpuComputer", it is composed of:<br>
</div>
<ul>
<li>4x large GPUs </li>
<li>4x medium GPUs (MIG devices)<br>
</li>
<li>16x small GPUs (Mig devices)<br>
</li>
</ul>
<div>Our plan is that we want to have one partition for each
class of GPUs. <br>
</div>
<div>So if a user chooses the "small" partition, it will only
see up to 16x small GPUs, and would not interfere with other
jobs running on the "medium" or "large" partitions. <br>
</div>
<div><br>
</div>
<div>Can I create three partitions and specify the corresponding
subset of GPUs for each one? <br>
</div>
<div><br>
</div>
<div>If not, would NodeName and NodeHostname serve as an
alternative way? i.e., to specify the node three times with
different NodeName, but all using the same
Hostname=gpuComputer, and specifying the corresponding subset
of "Gres" resources for each one. Then on each partition, to
choose the corresponding NodeName. <br>
</div>
<div><br>
</div>
<div>Any feedback or advice on the best way to accomplish this
would be much appreciated.</div>
<div>best regards<br>
