I am a recent IFB user and maybe I did something wrong because I don't seem to be able to SSH back to my account asilva.
I get this message:
shell request failed on channel 0
Could you help me figure out what to do to be able to ssh again?
The source of that problem is that you are running your jobs directly on the login node. These compute jobs take all authorized ressources and block your ssh access to the login node.
I had to stop them in order to give you access again to the cluster.
The login node is a small gateway to the cluster, you must use slurm commands like "sbatch" or "srun" to execute your scripts on the compute cluster nodes. You can find an introduction of slurm commands at https://ifb-elixirfr.gitlab.io/cluster/doc/slurm_user_guide/.
