Hello,
I'm setting Slurm in a number of machines and (at least for the moment)
we don't plan to let users submit across machines, so the initial plan
was to install Slurm+slurmdbd+mysql in every machine.
But in order to get stats for all the machines and to simplify things a
bit, I'm planning now to have only on mysql server running in a separate
machine and to collect all job data there.
What would make more sense?
+ 1) to install only one slurmdbd+mysql and configure all slurmctlds to
communicate with the single slurmdbd, or
+ 2) to have a slurmdbd in every machine and only one mysql to which all
slurmdbds connect?
Right now I have 2) working, but I wonder if there are pros/cons that I
have not considered yet for option 1)
Maybe you want to use Slurm federated clusters with a single database,
see https://slurm.schedmd.com/federation.html
There is a presentation at https://slurm.schedmd.com/SC17/FederationSC17.pdf
I hoe this helps.
