Hi,
I am new to this list. I have a small cluster (3 physical compute nodes, (8 cores/16 threads/64GB ram each) head node & VM-FE) with qlustar 12.0 installed. I am using it to run the Einstein Toolkit (numerical general relativity package). I would like to setup a physical front-end node for my system. My questions are:
1. Does the physical front-end node have to be net-bootable (via the head node)? 2. What qlustar software do I need on it? Is there an automated method for installing it? 3. Do I have to manually install slurm on it to submit jobs to the cluster from the physical front end node? 4. Do I need to register the physical front end node in qluman-qt?
Thanks for any help you can provide. Tony...

strictly speaking no (you can install a machine on disk and configure everything correctly manually of course, but that would be quite silly).
So best to just register the machine like any other node, configure it in QluMan essentially the same way as the VM FE and boot. That's it.

See above.

No, see above.

Yes, see above.

Roland,
Many, many thanks! I was able to setup a physical front end on an Odroid-H2 Single board computer (quad core, 2.5 GHz, 16GB). I have it registered in Qluman and even setup its own chroot/image so that I can install packages specifically for my front ends.

well done. That's exactly the right idea (setup its own chroot/image if needed). Good luck with your research,
