Abstract

The Deep Underground Neutrino Experiment (DUNE) will be the world’s foremost neutrino detector when it begins taking data in the mid-2020s. Two prototype detectors, collectively known as ProtoDUNE, have begun taking data at CERN and have accumulated over 3 PB of raw and reconstructed data since September 2018. Particle interaction within liquid argon time projection chambers are challenging to reconstruct, and the collaboration has set up a dedicated Production Processing group to perform centralized reconstruction of the large ProtoDUNE datasets as well as to generate large-scale Monte Carlo simulation. Part of the production infrastructure includes workflow management software and monitoring tools that are necessary to efficiently submit and monitor the large and diverse set of jobs needed to meet the experiment’s goals. We will give a brief overview of DUNE and ProtoDUNE, describe the various types of jobs within the Production Processing group’s purview, and discuss the software and workflow management strategies are currently in place to meet existing demand. We will conclude with a description of our requirements in a workflow management software solution and our planned evaluation process.

Highlights

  • Introduction to DUNEThe Deep Underground Neutrino Experiment is an international mega-science project that aims to probe the nature of the universe through a variety of methods such as studying neutrino oscillations, searching for proton decay, and collecting a large neutrino flux from a core-collapse supernova in our galaxy

  • In addition to the main detectors two prototype detectors are currently operational at CERN: ProtoDUNE Single-Phase (SP) and ProtoDUNE Dual-Phase (DP)

  • Within the overall Computing Consortium, the Production Group is currently responsible for running central reconstruction on ProtoDUNE raw data, large-scale Monte Carlo (MC) generation for all detectors, and works with the data management group to curate datasets

Summary

Introduction to DUNE

The Deep Underground Neutrino Experiment is an international mega-science project that aims to probe the nature of the universe through a variety of methods such as studying neutrino oscillations, searching for proton decay, and collecting a large neutrino flux from a core-collapse supernova in our galaxy. In addition to the main detectors two prototype detectors are currently operational at CERN: ProtoDUNE Single-Phase (SP) and ProtoDUNE Dual-Phase (DP). These detectors utilize the same technology and design (at approximately 5% scale) intended for the Far Detector modules and serve as technology demonstrators for the larger project. The ProtoDUNE-SP detector took approximately six weeks of data with beam on a staggered schedule from September to November 2018. Another beam run is planned for 2022 with both the SP and DP detectors.
