Introduction

The CRAB @ FNAL tutorial is a hands-on introduction to distributed user analysis within the CMS computing model.

The goal of this tutorial is to prepare all participants to use and succeed in using the GRID for their analyses.

Schedule

Prerequisites / Requirements

All participants are advised to start early with the registration processes as the individual processes can take some time (order of days) to be processed.

Registration

To guarantee successful participation, proof of a valid GRID certificate is needed for the registration. Each user has to execute two commands on the cmsuaf/cmslpc and send the output of the second command with the registration e-mail to gutsche AT fnal.gov:

  • Execute the generation of a GRID certificate proxy with:
    voms-proxy-init -voms cms
    
  • Check the validity of the generated proxy with the following command:
    voms-proxy-info -all
    
    which should produce output similar to:
    subject   : /DC=org/DC=doegrids/OU=People/CN=Oliver Gutsche 103748/CN=proxy
    issuer    : /DC=org/DC=doegrids/OU=People/CN=Oliver Gutsche 103748
    identity  : /DC=org/DC=doegrids/OU=People/CN=Oliver Gutsche 103748
    type      : proxy
    strength  : 512 bits
    path      : /tmp/x509up_u12840
    timeleft  : 11:59:54
    VO        : cms
    subject   : /DC=org/DC=doegrids/OU=People/CN=Oliver Gutsche 103748

    attribute : /cms/Role=NULL/Capability=NULL
    attribute : /cms/uscms/Role=NULL/Capability=NULL
    timeleft  : 11:59:54
