This an example of how to install a Torque/PBS cluster:

- hosts: server
  roles:
  - { role: 'indigo-dc.slurm', slurm_type_of_node: 'front', slurm_server_ip: '{{ansible_default_ipv4}}', slurm_wn_nodenames: "{{ groups['wns']|map('extract', hostvars, 'ansible_hostname')|list }}" }

- hosts: wns
  roles:
  - { role: 'indigo-dc.slurm', slurm_type_of_node: 'wn', slurm_server_ip: "{{hostvars['server']['ansible_default_ipv4']}}" }
