Once it is done, you can simply connect to the frontend by doing:

ssh front.dalek.lip6

Danger

Please change your password at your first connection to the frontend node by running the following command: 

passwd

To directly connect to a compute node, you can do (here az4-n4090-0 node):

ssh az4-n4090-0.dalek.lip6.srun

To connect to a compute node, there are three possible suffixes supported in the previous SSH configuration file. The philosophy is to encapsulate, first the connection to the Dalek frontend (with the proxy jump via the gateway if needed) and then, do the following depending on the suffix:

  • .srun: Allocates a node via SLURM srun command (in interactive mode): Reserves one CPU (= 1 CPU HW thread in SLURM) and no GPU. Here is an example of use: 
    ssh az4-n4090-0.dalek.lip6.srun
  • .srex: Allocates a node via SLURM srun command (in interactive mode) and in exclusive mode: Reserves all the available resources (= all the available CPU HW threads + all the available GPUs). Here is an example of use: 
    ssh az4-n4090-0.dalek.lip6.srex
  • .ssh: Connects to a node via SSH, this requires the node to be firstly reserved in exclusively mode via SLURM. This is convenient to open additional TTYs on a node. Here is an example of use: 
    ssh az4-n4090-0.dalek.lip6.ssh

Info

The first login to a node can take some time because the previous command will wake up the node before to allocate it to you. Generally it takes around 30 seconds and can take up to 3 minutes if the node is poweroff.

Info

The node keys have been changed in October 2025, you can safely remove the previous ones from you known_hosts file if you have connected to a node before. Otherwise, if you encounter an error connecting to a node, please check that the public key matches and contact the cluster administrator otherwise.
