Hi 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).
