Also found my answer for the weight value here
https://slurm.schedmd.com/priority_multifactor.html#fairshare
IMPORTANT: The weight values should be high enough to get a good set of
significant digits since all the factors are floating point numbers from 0.0 to
1.0. For example, one job could
Fix the issue with TRESBillingWeights,
It seems like I will need to set PartitionName for it to work

Thanks Luke.. Will go through the 2 commands (will try to digest them)
Wondering if you're able to advise on

slurm.conf but slurm fail to start

Hi,
I'm very new to Slurm and try to understand basic concepts. One of them
is the "Multifactor Priority Plugin". For this I submitted some jobs and
looked at sshare output. To my surprise I don't get any numbers for
"RawUsage", regardless what I do RawUsage stays 0 (same in "scontrol

I have updated the "pestat" tool for printing Slurm nodes status with 1
line per node including job info. The download page is

Sajesh,
For those other users that may have run into this. I found a reason why srun
cannot run interactive jobs, and it may not necessarily be related to

If one straces the slurmd one may see (see arg 3 for gid)
chown("/dev/pts/1", 1326, 7) = -1 EPERM (Operation not permitted)
I just checked my cluster and my spool dir is
SlurmdSpoolDir=/var/spool/slurm
(i.e. without the d at the end)
It doesn't really matter, as long as the directory exists and has the
correct permissions on all nodes

I think I've worked out a problem
I see in your slurm.conf you have this
SlurmdSpoolDir=/var/spool/slurm/d
It should be
SlurmdSpoolDir=/var/spool/slurmd
You'll need to restart slurmd on all the nodes after you make that change
I would also double check the permissions on that directory on
It looks like your ctl isn't contacting the slurmdbd properly. The control
host, control port etc are all blank.
The first thing I would do is change the ClusterName in your slurm.conf
from upper case TUC to lower case tuc. You'll then need to restart your
ctld. Then recheck sacctmgr show cluster
sinfo -N -o "%N %T %C %m %P %a"

It looks like your attachment of sinfo -R didn't come through
It also looks like your dbd isn't set up correctly
Can you also show the output of
sacctmgr list cluster
and
scontrol show config | grep ClusterName
