<div><br>
</div>
<div>If the master is set to not be an exec node, the worker nodes can be a different type. The situation you describe, (small master instance, large compute instances) is my current set up.</div>
<div><br>
</div>
<div>I believe things are different when the master is set as an exec host. </div>
<div><br>
</div>
<div>Cheers,</div>

<div dir="ltr">Hi,
<div><br>
</div>
<div>I have been doing some testing with starcluster and I see that by default every machine is the same type of instance and that the sge_master is also an sge_exec node.</div>
<div><br>
</div>
<div>I have read in the documentation that the sge plugin allows to configure the master node to not being an exec node. </div>
<div><br>
</div>
<div>The ideal setup for me would be to have the master node being a small instance just running the sge_master and not running jobs and the compute nodes being bigger instances in terms of hardware resources.</div>
<div><br>
</div>
<div>is this setup currently possible in starcluster? or is mandatory that every machine is the same kind of instance?</div>
<div><br>
</div>
<div>thanks for your help.</div>
<div><br>
</div>
<div>Pablo.</div>
