Thank you David! Let me try it.
Thinking about our case, I'll try to dump the debug info to somewhere like
syslog. Anyway, the idea should be useful to improve our system monitoring.
Much appreciated.
Best,

We have several users submitting single GPU jobs to our cluster. We expected
the jobs to fill each node and fully utilize the available GPU's but we instead
find that only 2 out of the 4 gpu's in each node gets allocated.
If we request 2 GPU's in the job and start two jobs, both jobs will
Short of getting on the system and kicking the tires myself, I’m fresh out of
ideas. Does “sinfo -R” offer any hints?

Hi,
I have some trouble understanding the "Oversubscribe" setting completely. What
I would like is to oversubscribe nodes to increase overall throughput.
- Is there a way to oversubscribe by a certain fraction, e.g. +20% or +50%?
- Is there a way to stop if a node reaches 100% "Load"?
Is there
Thanks, all for your replies. I think I can figure out something that makes
sense from here...

Weird. “slurmd -Dvvv” ought to report a whole lot of data; I can’t guess how to
interpret it not reporting anything but the “log file” and “munge” messages.
When you have it running attached to your window, is there any chance that
sinfo or scontrol suggest that the node is actually all right?
Spare capacity is critical. At our scale, the few dozen cores that were
typically left idle in our GPU nodes handles the vast majority of interactive
work.

That's pretty slick. We just have a test, gpu_test, and remotedesktop
partition set up for those purposes.
What the real trick is making sure you have sufficient spare capacity
that you can deliberately idle for these purposes. If we were a smaller
shop with less hardware I wouldn't be able
That’s close to what we’re doing, but without dedicated nodes. We have three
back-end partitions (interactive, any-interactive, and gpu-interactive), but
the users typically don’t have to consider that, due to our job_submit.lua
plugin.
All three partitions have a default of 2 hours, 1 core, 2
Is the time on that node too far out-of-sync w.r.t. the slurmctld server?

If you omitted the “-D” that I suggested, then the daemon would have detached
and logged nothing on the screen. In this case, you can still go to the slurmd
log (use “scontrol show config | grep -I log” if you’re not sure where the logs
are stored).

I tried by executing the debug mode but there also it is not writing
anything.
i waited for about 5-10 minutes
deda1x1452:/etc/sysconfig # /usr/sbin/slurmd -v -v
No output on terminal.
The OS is SLES12-SP4 . All firewall services are disabled.
The recent change is the local hostname earlier

Hi: please mention the below output.
cat /etc/redhat-release
OR
cat /etc/lsb_release
Also, please let us know the detailed log reports that is probably
available at /var/log/slurm/slurmctld.log

Hi Navin,
try running slurmd in the foregrund with increased verbosity:
slurmd -D -v (add as many v as you deem necessary)
Hopefully it'll tell you more about why it times out.
Best,

Navin,
As you can see, systemd provides very little service-specific information. For
slurm, you really need to go to the slurm logs to find out what happened.
Hint: A quick way to identify problems like this with slurmd and slurmctld is
to run them with the “-Dvvv” option, causing them to log

Hi,
is there a way to make interactive logins where users will use almost no
resources "always succeed"?
In most of these interactive sessions, users will have mostly idle shells
running and do some batch job submissions. Is there a way to allocate "infinite
virtual cpus" on each node that
