JLab Farm Quick Start

If you will be running eic-shell on the JLab farm systems, some pointers for getting started on the JLab farm are included below.

Connecting to an iFarm node

---

Before connecting to an iFarm node, you must first connect to the login node via -

BASH

ssh USER@login.jlab.org

Where you should replace USER with your username. You will be prompted to enter your password. For the login node this is your PIN + two-factor token. Do not insert a space between the PIN and token. Once on the login node, you can then connect to an interactive node via -

BASH

ssh USER@ifarm9

You will again be prompted for your password, this time, it’s your CUE password.

Other iFarm nodes can be specified if desired. Additionally, you can also just use -

BASH

ssh -J USER@login.jlab.org USER@ifarm9

to do both steps at once.

See this Service Now documentation for further pointers and assistance.

For running larger/longer simulation/reconstruction jobs, you may find the scripts in the snippets repository useful.
