There was a problem hiding this comment.
When the amount of RAM, we want to reserve for the OS and everything else that is not a Slurm job, does not depend on the amount of cores, it does not make sense to multiply values here. Instead of
slurm_max_mem_per_node: "{{ slurm_real_memory - 8 * 512 }}"
you can just use:
slurm_max_mem_per_node: "{{ slurm_real_memory - 4096 }}"
That will fail though on a small VM, which only has 4096 GB RAM in total.
slurm_max_mem_per_node: "{{ slurm_real_memory - slurm_sockets * slurm_cores_per_socket * 512 }}"
is a more flexible setup.
