We have our latest cluster software stack for a distributed set of clusters built on Ansible: https://github.com/CSC-IT-Center-for-Science/fgci-ansible
A recent presentation at the SLURM User Group on Ansiblizing SLURM: https://gitpitch.com/CSC-IT-Center-for-Science/ansible-role-slurm/gitpitch I see benefits also in being able to share playbooks and collaborate on improving them with other teams in our organization and the Universities, even ones working in non-HPC areas.
