Bash script to send one GuineaPig++ onto the Grid

Before doing anything on the Grid be sure you have a valid proxy …

grid-proxy-init

To send Job onto the Grid you must give some Grid parameters:

• your virtual organisation (VO), ilc by default
• the LCG_CATALOG_TYPE, defined as lfc if you are under ilc vo
• the LFC_HOST, defined as grid-lfc.desy.de if you are under ilc vo
• YOU MUST HAVE A VALID FOLDER ON A STORAGE ELEMENT (SE), there will be no default
  value !!!
  you can create a folder on a SE like this:
   

  lfc-mkdir /grid/ilc/TOTO

Ask the Grid User Support @ your lab. if you don’t know the anwser …

(or wget http://flc.web.lal.in2p3.fr/mdi/BBSIM/GPontoGrid/gp_grid_cfg.sh

also available here: http://dadoun.net/Informatique/Download/gp_grid_cfg.sh).

Change the file access control list: chmod +x gp_grid_cfg.sh.

Execute it on your User (grid) Interface (UI): ./gp_grid_cfg.sh .

It will create a launch_gp_grid.sh file with all the configuration variables you gave.

Now you can submit a GuineaPig++ job onto the grid, 3 arguments is needed:

• the acc.dat

(if the previous link don’t work try this one
the acc.dat you may need also this
file (.template) file to run
correctly the bash script)

• accelerator
• parameter_set

With the acc.dat from above try like this:

./launch_gp_grid.sh acc.dat ILC LC-GENERAL

Here a typical echo from a LAL User Interface:

lx3/dadoun % ./launch_gp_grid.sh acc.dat ILC LC-GENERAL

Selected Virtual Organisation name (from --vo option): ilc
