Subject: [slurm-dev] Re: Why my slurm is running on only one node?
Also - are the nodes up an running wrt SLURM? What is the output of :
sinfo -N
?
(fwiw, I really like the alias sn="sinfo -Nle -o "%.20n %.15C %.8O %.7t" |
uniq" )

I think it's because hostname is so undemanding.
How many CPUs does each host have?
You may need to use ((number of cpus per host) + 1) to see action on another
node.
You can try using stress-ng to test higher loads?

I have 5 nodes include control node.
and my nodes are looking like this
Control Node : GO1
Compute Nodes : GO[1-5]
when i trying to allocate some job to multiple nodes, only one node works.

$ srun -N5 hostname
GO1
GO1

even I expected like this
$ srun -N5 hostname
