<p>Generally, you can think of federation as a way to centrally
track and manage your multiple clusters. More of a way to run
single 'sreport' and 'sacct' commands. There are added abilities
such as being able to specify the cluster to send a job to, but
for all intents and purposes, the clusters themselves are
independent.</p>
<p>It sounds like what you may want is multiple partitions in the
same cluster. You can have 2 that comprise of the sets of nodes
and a third that is comprised of all nodes. Or a single partition
with all nodes and have features that delineate what node can do
what (a node-locked license, for example). Then you can send a job
to a specific subset of nodes.</p>
<p>Quite a few other ways to design the ability you describe, but
separate clusters is not one of them.</p>

<div>Just out of interest, I wonder what the exact difference
between slurm multi-cluster and federation (apart from unique
job id, and federation limitations) is. Usually, I use the
"-Mall" option with multi-cluster. Initially, I thought the
federation will send tasks to more than on cluster at once
(e.g., I had 2 clusters, each cluster has 2 nodes, and each
node has 8 CPUs. I submitted more than 16 tasks, and though
the federation will submit 16 tasks to the first cluster, and
the additional tasks to the second cluster. But, it seems the
federation acts similarly to the multi-cluster as only one
cluster receives the tasks).</div>
