Setting up Ganga for use at Nikhef

Setup the correct environment

Only use slc5 machines if you want to use Dirac, parret is now also slc5.

Dirac needs server certificates to work. They are installed, but 2 environment variables must be set to point Dirac to where they are. This is done for you in a simple script prepared by Gerhard.

• Put the following into your login script:

source /project/bfys/lhcb/sw/setup.sh

• Remove any other sourcing of LbLogin scripts from your startup scripts and from private scripts to setup the LHCb software.
• The setup script must be sourced in your startup script if you want to run LHCb software jobs on stoomboot.

Run only the first time you ever use Ganga

Generate a default configuration file

SetupProject Ganga
ganga -g

Edit ${HOME}/.gangarc and make the following changes:

• Look for [PBS] , uncomment submit_res_pattern and change it into:

submit_res_pattern = ^(?P<id>\d*)\.allier\.nikhef\.nl

• Look for [DIRAC], change AllowedPlatforms:

AllowedPlatforms = ['slc4_ia32_gcc34', 'x86_64-slc5-gcc43-opt']

Run once for every new ganga version

Setting up the user directory

SetupProject Ganga --build-env

To start Ganga:

In a fresh shell
