SSH Access

To use the cluster you need to ask for the creation of a user account to an administrator. Once you have an account, you can connect easily using ssh.

To facilitate the ssh usage, you can copy-paste the following lines into your $HOME/.ssh/config file and replace [USER_MONOLITHE] with your Monolithe login and [USER_LIP6] with your LIP6 login:

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

ssh front.mono.lip6

It is also possible to directly connect to a specific node using the Slurm partition identifier. For instance, if you want to directly connect to the Raspberry Pi 4 you can do:

ssh rpi4.mono.lip6

Danger

It is not possible to directly connect to a node using the NFS accounts. You should always use the srun command from the frontend. For instance, the following command will always fail: 

ssh user-nfs@opi5.mono.proj.lip6.fr
