CERN@school

Introduction

This is the wiki homepage for GridPP activity on CERN@school.

Getting Started

• Get logged on and set-up in a working area with access to the Grid.
• Make sure you've got your Grid certificate installed on your system (i.e. in .globus)
• Initialise you proxy:

voms-proxy-init --voms cernatschool.org

• Find the WMS sites that are supported by the CERN@school VO:

lcg-infosites wms

• Then ensure that the environment variable GLITE_WMS_WMPROXY_ENDPOINT points to one of these WMSs:

export GLITE_WMS_WMPROXY_ENDPOINT=https://wms02.grid.hep.ph.ic.ac.uk:7443/glite_wms_wmproxy_server

Technical Details

Local File Catalog (LFC)

This can be found by using the command:

lcg-infosites lfc --vo cernatschool.org

which returns lfc.gridpp.rl.ac.uk. See the "Data Management" section of the crash course for more information.

CERN@school on the Cloud

• Running Allpix (GEANT4) on the CERN@school VO.

Examples

These example programs are in development:

• Hello World!;
• A simple frame reader for Timepix detector frames.

The cernatschool.org Virtual Organisation (VO)

The CERN@school VO represents the CERN@school project on the Grid. CERN@school aims to bring CERN technology into the classroom to aid with the teaching of physics and to inspire the next generation of scientists and engineers. The CERN@school VO will allow students and teachers involved with the project to harness GridPP to store and analyse data from the CERN@school detectors, the LUCID experiment and the associated GEANT4 simulations.
