A bit of an ugly hack,

Is there no way to set or define a custom variable like at node level and
then you pass the same variable in the job request so that it will land
into those nodes only.

Somewhat tested, but should work or at least be a starting point. Given a job
number JOBID that’s already running with this license on one or more nodes:
sbatch -w $(scontrol show job JOBID | grep ' NodeList=' | cut -d= -f2) -N 1

To explain with more details.
job will be submitted based on core at any time but it will go to any
random nodes but limited to 4 Nodes only.(license having some intelligence
that it calculate the nodes and if it reached to 4 then it will not allow
any more nodes. yes it didn't depend on the no
To make sure I’m reading this correctly, you have a software license that lets
you run jobs on up to 4 nodes at once, regardless of how many CPUs you use?
That is, you could run any one of the following sets of jobs:
- four 1-node jobs,
- two 2-node jobs,
- one 1-node and one 3-node job,
- two
Thanks Micheal.
Actually one application license are based on node and we have 4 Node
license( not a fix node). we have several nodes but when job lands on any 4
random nodes it runs on those nodes only. After that it fails if it goes to
other nodes.
can we define a custom variable and set it on
Haven’t done it yet myself, but it’s on my todo list.
But I’d assume that if you use the FlexLM or RLM parts of that documentation,
that Slurm would query the remote license server periodically and hold the job
until the necessary licenses were available.

Thanks Michael,
yes i have gone through but the licenses are remote license and it will be
used by outside as well not only in slurm.
so basically i am interested to know how we can update the database
dynamically to get the exact value at that point of time.
i mean query the license server and
Have you seen https://slurm.schedmd.com/licenses.html already? If the software
is just for use inside the cluster, one Licenses= line in slurm.conf plus users
submitting with the -L flag should suffice. Should be able to set that license
value is 4 if it’s licensed per node and you can run up
Hi Team,
we have an application whose licenses is limited .it scales upto 4
nodes(~80 cores).
so if 4 nodes are full, in 5th node job used to get fail.
we want to put a restriction so that the application can't go for the
execution beyond the 4 nodes and fail it should be in queue state.
i do not
