  DUNE Computing Consortium

The DUNE Computing Consortium works to establish a global computing network that will handle the massive data streams produced by distributing these across the computing grid. Selected consortia members coordinate DUNE computing activities to new members to acquaint them with the specific and DUNE software and resources.

DUNE Computing Consortium Coordinator: Michael Kirby (Brookhave National Laboratory)

This is a short 3 hour version of the basics which follows the agenda at Indico 75882.

We will be adding/offering additional tutorials. An important recent one is:

The LArSoft tutorial at CERN, February 3-7, 2025 password on the tutorials page

Basic setup reminder

You should have gone through the setup sequence

As a reminder you need to choose between running on sl7 in a container or al9. You do NOT want to mix them.

You also need to be starting in a clean terminal session. We recommend not having a .profile or .login at all and deliberately creating setup scripts that you source whenever you start using DUNE code.

If you did the setup you made one of these in your home area.

source dune_presetup_2026_al9.sh 
# We just renamed these so you may still have dune_presetup_2025_al9.sh

Here are some example scripts that do most of the setups explained in this tutorial. You need to store these in your home area, source them every time you log in, and possibly update them as code versions evolve.

• SL7 setup

• AL9 setup RECOMMENDED

If you run into problems, check out the Common Error Messages page and the FAQ page

if that doesn’t help, use Slack to ask us about the problem - there is always a new one cropping up.

Support

You must be on the DUNE Collaboration member list and have a valid FNAL or CERN account. See the old [Indico Requirement page][indico-event-requirements] for more information. Windows users are invited to review the Windows Setup page.

You should join the DUNE Slack instance and look in #computing-training-basics for help with this tutorial

go to https://atwork.dunescience.org/tools/ scroll down to Slack and request an invite. Please do not do this if you are already in DUNE Slack.
