### Creazione utenti
Affinché un programma possa essere lanciato su tutti i nodi è necessario che l'**utente** sia disponibile su ciascuno di essi, il seguente script si occupa di replicare l'utente ovunque sia necessario:
```bash
#!/bin/bash
#
# Add a SLURM user to the Steffè cluster
# A good place for this script is in:
# /usr/local/bin/cluster-users
set -e
cluster_hosts="steffe0 steffe1 steffe2 steffe3 steffe4 steffe5 steffe6 steffe7 steffe8 steffe9 steffe10 steffe11 steffe12 steffe13 steffe14 steffe15 steffe16 steffe17 steffe18 steffe19"

}
