Thank you for that - I'm restricting things via limits.conf on the login
nodes at the moment, but have been considering using cgroups instead for
a while. So this is very useful :)
If we're sharing details, our setup currently is:
2x2 cluster not-quite-federations - prod and dev, each with a
cpu limit using ulimit is pretty straightforward with pam_limits and
/etc/security/limits.conf. On some of the login nodes we have a cpu limit
of 10 minutes, so heavy processes will fail.
The memory was a bit more complicated (i.e. not pretty). We wanted that a
user won't be able to use more than
That is interesting to me.
How do you use ulimit and systemd to limit user usage on the login
nodes? This sounds like something very useful.

Hello,
I have the database on a separate server (it runs the database and the
database only). The login nodes run nothing SLURM related, they simply
have the binaries installed & a SLURM config.
I've never looked into having multiple databases & using

Thank you Tina.
so if i understood correctly.Database is global to both cluster and running
on login Node?
or is the database running on one of the master Node and shared with
another master server Node?
but as far I have read that the slurm database can also be separate on both
the master and
Hi Navin,
well, I have two clusters & login nodes that allow access to both. That
do? I don't think a third would make any difference in setup.
They need to share a database. As long as the share a database, the
clusters have 'knowledge' of each other.
So if you set up one database server
Hi ,
I am looking for a stepwise guide to setup multi cluster implementation.
We wanted to set up 3 clusters and one Login Node to run the job using -M
cluster option.
can anybody have such a setup and can share some insight into how it works
and it is really a stable solution.

Navin.
