Batch Computing Basics for DUNE - 2025 transition edition

This tutorial will teach you the basics of DUNE batch computing.

Instructors will engage students with hands-on lessons focused in three areas:

1. The justIn batch system
2. The jobsub batch system

Mentors will answer your questions and provide technical support.

Prerequisites

1. Unix command line experience is necessary for this training. We recommend that participants to go through The Unix Shell, if new to the unix command line (also known as terminal or shell).
2. A computer set up so that you can log into a remote unix system at FNAL or CERN.
   This will include getting DUNE computing accounts at FNAL or CERN.
   See Setup to do this pre-class setup.

By the end of this workshop, participants will know how to:

• submit simple jobs using the justIn batch system
• know some simple methods for debugging batch jobs

There are additional materials provided that explain how to:

• Use the justIn system to process data
• Develop configuration files to control jobsub batch jobs

You will need to be a DUNE Collaborator (listed member), and have a valid FNAL or CERN computing account to join the tutorial. Contact your DUNE group leader for assistance.

Getting Started

First step: follow the directions in the “Setup”. Once you follow the instructions; we give you an easy exercise to make sure you are good to go.
