[slurm-users] pam_slurm_adopt and multiple jobs on the same worker node

[Massimo Sgaravatto via slurm-users]

Dear all

With the pam_slurm_adopt module as far as I understand you can ssh to a worker node if there is at least a job running on the node by that user. 

If there are multiple jobs, if I am not wrong you will be "mapped" to the last job started on the node. And, if you are using cgroups, you will be "confined" to the resources assigned to this "last" job.

Is it possible in some way to specify the job to be mapped, in case there are multiple jobs for that user on the same node ?

Thanks, Massimo

Instead of using pam_slurm_adopt your users can get a shell on the node
of a specific job in that job's "mapped" space by running

srun --pty --overlap --jobid JOBIDNUM bash
