What about Grid Mode?

I am guessing you have each one of these clusters in a separate partition.
How big are these clusters? You can turn off the communication by just set up
the treewidth to the number of nodes in you system.
Is there any reason you don't want to/can't use the multi cluster
functionality, and operate in traditional SLURM fashion with 1 slurmctld per
cluster?

Subject: [slurm-dev] two clusters / one scheduler
I'd like to have a single slurm instance schedule jobs onto two
physically disjoint clusters. The compute nodes of one cluster cannot
reach the compute nodes of the other cluster, but they can all see the
scheduler nodes. With slurm's hierarchical communication, when some
nodes can't reach others slurm thinks the nodes are not responding and
would eventually mark them offline. Is there any way to logically group
nodes into separate communication groups to avoid this problem?
