nvidia-persistenced is something that gets installed by the nvidia driver. Setting it to start at boot time helps with slurmd being able to find the GPUs when it tries to start. This is just one web page that has some information about it.

Hi there all,

We have Dell server with 2 x Nvidia H100 and running slurm on it. After restart server if we do not write nvidia-smi command slurm fails. When we run nvidia-smi && systemctl restart slurmd && systemctl restart slurmctld , slurm queue begins. Do you have any idea about this error and what can we do for this issue?

It sounds to me perhaps as though your systemd units are starting in the wrong order, or don’t have appropriate dependencies set in them?
