We run at about 50 PF and 1.5k nodes with about 100,000 jobs per day and
we use 25.05.4, though we tend to upgrade to latest available so we will
be upgrading to 25.11.* soon (when the .1 release comes out). If you are
interested I'm happy to share our slurm.conf.
At least from my experience the latest releases have been stable, though
you want to avoid .0 releases unless you want to be bleeding edge or
need a feature. Most of the kinks are worked out by .1, definitely by .2
of any major release. There still may be weird edge cases but in general
it is stable.

I would take a step back and ask how you intend to install and manage
this cluster.
CPU only or GPUs ?
OS ?
Interconnect fabric?
Storage ?
Power per rack? Cooling?
Monitoring?

We are currently planning to deploy a new HPC system with a total
compute capacity exceeding 100 PF. As part of our preparation, we
would like to understand which Slurm versions are considered
stable and widely used at this scale.
Could you please share your recommendations or experience regarding:
1. Which Slurm version is currently running reliably on very
large-scale clusters (>100 PF or >10k nodes)?
2. Whether there are any versions we should avoid due to known
issues at large scale.
3. Any best practices or configuration considerations for Slurm
deployments of this size.
