Abstract

ROOT is an object-oriented framework for large-scale data analysis. PROOF, the Parallel Root Facility, is an extension of ROOT which enables interactive parallel large-scale analysis on a cluster. PROOF Lite, a dedicated version of PROOF, allows to analyse the data on a multi-core computer. In the first part of ROOT/PROOF tutorial the participants will be introduced to ROOT and tools for analysis and visualisation of the data on a desktop machine. Participants will learn how to design and use a custom event class for analysis of data stored in ROOT tree structure. This will be followed by the second part where the structure of the PROOF system and tree/selector-based analysis will be explained. Participants will run analysis tasks on multi-core desktop systems and on a dedicated PROOF cluster in practical exercises.


Prerequisites

  • Login/password provided by School organisers in your personal information sheet to connect to UI (user interface) machines. Machines will have ROOT software installed.
  • If you plan to use your laptop instead of UI you should have installed ROOT on the laptop. You can download ROOT here.
