This description is not supposed to replace the various howto's for running jobs on the Grid. It is merely a summary of what I have to do to run jobs on the grid. If people use it as their howto - go ahead.

This guide uses the jdlgen, status, ... scripts written by Alessandro de Salvo. Please have a look at this webpage written by James Catmore and setup the right environment.

Step by step to the grid:

  • Get a certificate smile
  • login to lxplus and type:
source /afs/cern.ch/project/gd/LCG-share/2.3.0/sl3/etc/profile.d/grid_env.sh
  • Get a very long certificate! If your grid token expires before the jobs are finished they will all be aborted.
grid-proxy-init -valid 100:00
gives you a proxy which last for 100 hours.
  • cd to your grid environment (as setup with James guide) and type
source setup.sh
  • create jdl job description files with the command jdlgen
jdlgen -r 9.0.4 -d 4020 -D tth120_bb --in-step evgen904 --out-step g4initial904 \
-p private -t 09-00-04-06 -e 2 --in-part 1:1 --out-part 1:5 -s castorgrid.ific.uv.es
--eta-min=-4. --eta_max=+4.
This line implies that you have ONE input file registered with the logical file name (LFN) private.004020.evgen904.tth120_bb._00001.pool.root. You want to have 5 output files with 2 events each simulated in an eta range of -4. to +4. You also need to have a template file in your templates directory with the name private.pythiaB.g4initial904.jdl.template.

I can register an input file with:

lcg-cr --vo atlas -d castorgrid.cern.ch -l <LFNofFile> -g guid:<PoolFileID> \
gsiftp://castorgrid.cern.ch/castor/cern.ch/grid/atlas/wildauer/<file>
The LFN of the file is arbitrary. As a convention it is simply the filename itself.
