Hi,
Can you please help me understand how the passwordless ssh works on SLURM?
I was under the assumption that jobs/tasks are ultimately submitted by the
"slurm" linux user and not by the linux user who wants to run jobs. Is this
not correct? So is it not sufficient for only the "slurm" linux use
Hi Durai,
I can only try to explain how I understand this: The "slurm" user runs
only the slurmctld and slurmdbd central server daemons. On the compute
nodes, the slurmd daemon runs as the root user so that it can start user
tasks on behalf of normal users.
The "slurm" user should *not* hav

All,
Has anyone successfully implemented the DNS SRV records for configs?
I am curious about where to put the SRV record (what domain/name) as we
have more than one cluster in the same domain.
Maybe that would not be supported. Cannot tell from the documentation at

I'll admit that I didn't know about this until I came to LANL, but
there's actually a much better alternative than having to create user
key pairs
Hi,
I am encountering a weird issue, and I'm not sure where it is coming from.
I have setup a slurm-based cluster using AWS ParallelCluster. I have tweaked
the slurm configuration to enable X forwarding by setting PrologFlags=X11. The
ParallelCluster portion is relevant, as basically every ti
Sounds like a race condition where slurmd is starting before the node is
truly ready.
You can try adding dependencies for slurmd so it will not start until
some other needed service is running.
The benefits of systemd :)

Hi Michael,
Thanks very much, this is really cool! I need to look into the
HostbasedAuthentication for intra-cluster MPI tasks spawned by SSH (not
using srun).
Presumably external access still needs to use SSH authorized keys?
Best regards,

Could you kindly elaborate on this statement? Is host-based security

Host-based security is not considered as safe as user-based security, so
should only be used in special cases.

Thanks, I tried that command but it looks to show the requested number of GPUs
instead of the GPU index. I tried ` sacct -j -l` too. However, it

It DOES NOT seem to include any GPU index, I meant. Sorry.
Best.
