<p>Oh you will also need a IB subnet manager (opensm) running since
you have an unmanaged switch. You can start this on one of the
compute nodes. I would probably start up 2 so you have
redundancy.</p>

<div> I have recently acquired a few ConnectX-3 cards and an

<div>Thus far, I have been able to verify that the cards and

<div>Though, I was wondering if anyone knew of any guide or

it work with SLURM would also be appreciated.<br>

<div>Thanks in advance for any suggestions, I am often a user of
clusters, but it is my first time setting one up.<br>
