Description Rob Sutton 2023-04-13 13:50:41 MDT

We are adding 6 nodes to our cluster and, as someone new to Slurm administration, I need assistance with the procedure for adding the new machines to the cluster. I have been unable to find the steps documented, can you please provide guidance as to the correct process to follow?

Hi,
Please take a look at the node configuration section of the slurm.conf documentation seen here:

https://slurm.schedmd.com/slurm.conf.html#OPT_NodeName 

You would need to setup the nodes in your slurm.conf as mentioned like so:

NodeName, NodeHostname, Port, CPUS, SocketsPerBoard, CoresPerSocket ThreadsPerCore, RealMemory and other parameters can all be added to each node.

I would suggest reading through the documentation and seeing what parameters you need.  The ones I mentioned are standard for node configuration but other options can be set that can be useful depending on your needs.

Please review and let me know if you have any questions.

Thanks

I would also like to add the following links that give a more detailed explanation on adding nodes in Slurm:

This will give you the needed steps to achieve this:

And here is some extra reading for more clarification:

Please let me know if anything is not clear.

Thanks

Hey Benny,

Thank you for the information! My new nodes arrived yesterday and are scheduled to be racked tomorrow. If possible, I would like to keep this bug open until I've added the nodes just in case I encounter issues or have questions?

Thanks,

Rob
