You say that you modified the file in a different way. It may be worth
checking file permissions as for some security functions files can be
ignored if they don't have the required permissions.
That said, that would show in the journal/ logs.

We use Active Directory and NFSv4 and I think that we have some instructions
for setting it up on CentOS 7. It was quite involved and does require that
the directory service returns UID and GID information, so have populated the
RFC2307 fields in AD. This is required for munge to work.

I think you do need a common authentication system between the submitting
node and the cluster, but that may just be what I'm used to.

We create the temporary directories using SLURM_JOB_ID, and that works
fine with Job Arrays so far as I can see. Don't you have a problem
if a user has multiple jobs on the same node?

If this is a single host machine I suggest checking the /etc/hosts file to make
sure that ‘mannose’ is listed as you expect. It is generally advised to use
FQDNs for host names; the fact that the message “connection to
host:mannose:6819: Connection refused” used a short name may mean that in a
that cannot be exclusive such as IO to storage.
We have used the --spread-jobs option with some success but I think it
spreads the jobs of a single sbatch file rather than cause a new job to
scale horizontally.
I'm sure others know better.

To process the epilog a Bash process must be created so perhaps look at
.bashrc.
Try timing running the epilog yourself on a compute node. I presume it is
owned by an account local to the compute nodes, not a directory service
account?

We build with CSI hardened nodes and /tmp is marked to block execution. It
causes occasional frustration but it would be important to be able to
redirect to a file system that allowed execution.

I can't immediately check what I do with Slurm but in several systemd files
I create sub folders of /var/run and set their ownership the same as the

I use CentOS (for now!).
I can post an actual service startup file in daylight if useful.

I think there would be no reason why a slurm node will care about traffic on
multiple interfaces as long as your configuration is set to listen on them,
e.g. no firewalld rules in the way restricting traffic to the private network.

I encountered the same problem, and as with munge I created a .te file that
can be built to create a policy to add to the compute nodes to fix this:

That is interesting as I run with SElinux enforcing.

I use the

So, is there a config to tune, an option to use in "sbatch" to achieve the same
result, or should I rather launch 20 jobs per node and have each job split in

For some services that display of 0.0.0.0 does include IPv6, although it is

I will admit that I have not used sbcast but from reading the man pages I think
that it does not do what you hope.
The sbcast command will indeed run on the first allocated node, so the source

What Marcus reports is quite correct. It can be confusing, and Slurm uses
'CPU' I think as a non-specific term to mean 'the smallest assignable
compute object'. With SMT enabled that is the thread, and with it
disabled it is the core.
We were told by the company that installed the cluster at m
There are differences for X11 between Slurm versions so it may help to know

Here is an example of a modified system service file which uses ExecStartPre to
create the directory under /var/run on the fly. This is for slurmctld. As

That will depend where the rest of the cluster is. If they were in the VPN

they might. But if they are elsewhere in your home network, they will not.

Agreed, I have just been setting up Lmod on a national compute cluster

In my last role we moved from SGE to Slurm.
However we did this by using VMs for all the control, login, slurmDBD and

where it needed compute nodes. We then removed compute nodes in groups from
SGE, reinstalled w

(pkglib_LTLIBRARIES)
pkglib_LTLIBRARIES = accounting_storage_slurmdbd.la
So I think that the problem is that the definition of pkglib_LTLIBRARIES is
commented out in the accounting_storage_mysql Makefile, hence nothing to
build.
Is that intended? Is it a consequence of something in my environment?

I built a cluster with Login Node, slurmctld, slurmdbd and MariaDb all on
VMs, and the compute nodes all physical. Works fine. Having a VM as login
node has the added benefit that anyone who tries to run an application
there interactively soon finds that it will not run in small RAM, and in
