Hi;
The Slurm is selecting the nodes according to the weight parameter of
the nodes. I don't know any settings to change the way of the selecting
node, except the changing values of the weights. But it is not a
suitable for the randomly selecting nodes.
Fortunately, absolutely there is not any reason that I know to randomly
selecting nodes. The modern hardware is not delicate as you thought.
Nevertheless, if you want to circulate the nodes, you can change weights
of the nodes, for example, at every three months.
Regards,
Ahmet M.

Hi,
Is there a scheduling option such that, when there are multiple nodes
that are equivalent in terms of available and allocated resources,
Slurm would select randomly from among those nodes?
I've noticed that if no other jobs are running, and I submit a single
job via srun, with no parameters to specify anything other than the
defaults, the job *always* runs on the first node in slurm.conf. This
seems like it would lead to some hosts getting overused and others
getting underused. I'd like the stress on our hardware to be
reasonably evenly distributed.
Thanks,
