CRAB @ FNAL Tutorial 27. June 2007


The CRAB @ FNAL tutorial is a hands-on introduction to distributed user analysis within the CMS computing model. The user will learn about the CMS computing model and the user GRID analysis tool CRAB. All information will be presented in the form of talks and hands-on exercises. The goal of this tutorial is to prepare all participants to use and succeed in using the GRID for their analyses.


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.


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

  • 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
    issuer    : /C=CH/O=CERN/OU=GRID/CN=host/
    attribute : /cms/Role=NULL/Capability=NULL
    attribute : /cms/uscms/Role=NULL/Capability=NULL
    timeleft  : 11:59:54
    Include the output in your registration e-mail. If one of the above steps fails, please follow and complete all described steps
