Getting connected

Logging in to NeSI resources is primarily accomplished via SSH (or “secure shell”). This is a method of getting a command-line interface on our clusters, which runs a version of the Linux operating system. For more details on how to connect to our systems, please visit

Connecting to the NeSI Clusters via SSH

If that sounds too intimidating, and you would like to try a zero-client web-browser approach to using NeSI, you can log in to our JupyterHub: https://jupyter.nesi.org.nz

For an introduction to the features of Jupyter on NeSI, check out Jupyter on NeSI

Transferring Files

Small files can be moved to and from NeSI systems inside of Jupyter. SCP (Secure CoPy) is another common method. If you have a large amount of data to move, you can schedule transfers via Globus on NeSI.

Submitting Jobs

Instructions to be executed by the node(s) assigned to you when your request for resources can be met by the scheduler – can get very complicated, so it’s best to refer to the documentation for the software you want to use to get started.

Submitting your first job

We also have a more detailed guide on the batch system that we recommend new users read. It provides information about scheduling, job submission and how to write scripts to accomplish various tasks.
