[slurm-users] federation vs multi-cluster

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).
