Running Art Tutorial

Tutorial Session Goal

In this Tutorial you will learn how to run the Mu2e 'art' framework executable (mu2e), both interactively and on the grid.

Session Prerequisites and Advance Preparation

• Perform the Tutorial on setting up the Mu2e Offline

Session Introduction

Art is a software framework for processing events with modular code with lots of run-time configurability. Art is controlled by scripts in a dedicated configuration language called fhicl (.fcl suffix). Art uses rootIO to store events.

This tutorial will cover how to build and run several different kinds of art jobs, and how to use the mu2e job tools to divide large projects into many separate jobs, and how to run those jobs in parallel on Fermigrid or the OSG (open science grid).

Exercises

NB: these are just suggestions, please add/remove/edit as you see fit. Link these to actual exercises

• run the mu2e executable directly from the release in the tutorial container
• create a satellite release on top of the tutorial release
• edit some configuration in your satellite to change the art behavior: debug-config, print, etc
• create a partial-checkout release of a single package from Offline
  • compile and link the package and rerun the mu2e app
• Explore the JobConfig scripts for various kinds of mu2e production jobs
• Run some simple production jobs
  • Primary Particle generation and simulation
  • Mixing
  • reconstruction
• setup and run generateFcl to prepare for grid running
• run mu2eProdSys --dryrun

Reference Materials

• art workbook
• various DocDBs that reference production, satellite release, partial checkout, etc.
