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 to 4 jobs simultaneously, or 4*NCPUS if it’s licensed per CPU, or 1 if it’s a single license good for one run from 1-4 nodes.
There are also options to query a FlexLM or RLM server for license management. -- Mike Renfro, PhD / HPC Systems Administrator, Information Technology Services 931 372-3601 / Tennessee Tech University > On May 5, 2020, at 7:54 AM, navin srivastava <navin.alt...@gmail.com> wrote: > > 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 want to keep a separate partition to achieve this config.is there a > way to achieve this scenario using some dynamic resource which can call the > license variable on the fly and if it is reached it should keep the job in > queue. > > Regards > Navin. > > >
