[slurm-users] GPU-node not waking up after power-save

[Ümit Seren]

We use power saving with our GPU nodes and they power up fine. They take a bit longer to boot but that’s it.
What do you mean with not waking up ?
The power on script is not called ?

Subject: [slurm-users] GPU-node not waking up after power-save
Hi,

We use Slurm's power saving mechanism to switch of idle nodes.  However,
we don't currently use it for our GPU nodes.  This is because in the
past these nodes failed to wake up again when jobs were submitted to the
GPU partition.  Before we look at the issue due to the current energy
situation, I was wondering whether this a problem others have (had).

So does power-saving work in general for GPU nodes and, if so, are there
any extra steps one needs to take in order to set things up properly?

Cheers,

Loris
