[slurm-users] Rolling reboot with at most N machines down simultaneously?

[Corentin Mercier]

Hello, 

I think you could use SLURM's power saving mecanism to shut down all your nodes simultaneously. 
Then doing srun -N<nb_nodes> -C <your_node_group> true (or any other small work) will wake up N nodes simultaneously. 
You can even do srun while your nodes are powering down, SLURM will reboot them as soon as they're powered down. 

I hope it will be helpful ! 

Regards,
