Jobs are submitted to the cluster via the login node (axon.rc.zi.columbia.edu) as show in the example below.
The login node is only accessible from wired connections, secure wifi or the CUIT VPN.
SSH from other Columbia hosts
While the login node is not currently accessible from the Internet, it is accessible from most parts of the Columbia so you can ssh from another host which is available on the Internet such as other HPC login nodes or Cunix.
Once logged into the cluster login node, axon.rc.zi.columbia.edu, compute jobs can be launched using the Slurm job scheduler.
To login to the cluster ssh into the login node (replace uni123 with your uni)
ssh uni123@axon.rc.zi.columbia.edu
