Axon is a Beowulf style cluster where a scheduler, in this case Slurm, is used to submit compute tasks, called jobs, to one or more nodes in the cluster. Jobs are submitted to the cluster via the login node (axon.rc.zi.columbia.edu) as show in the example below.
| Warning | ||
|---|---|---|

The login node is for preparation of compute jobs, please don't run any cpu intensive tasks on the login node. Compute intensive preparation can be done via Slurm interactive jobs on the compute nodes. |

The login node is only accessible from wired connections inside the Columbia Morningside campus, secure wifi or the CUIT VPN at this time. 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. |
