In addition to the ThinLinc and OnDemand interfaces, users can also choose to run interactive jobs on compute nodes,to obtain a shell that they can interact with. This gives users the ability to type commands or use a graphical interface as if they were on a login node.
To submit an interactive job, use
sinteractive to run a login shell on allocated resources.
sinteractive accepts most of the same resource requests as sbatch, so to request a login shell in the compute queue while allocating 2 nodes and 256 total cores, you might do:
$ sinteractive -N2 -n256 -A oneofyourallocations
