---++ GANGA examples

_Note1_: There is an installed copy of _GANGA_ software on the [[http://www.grid.kfki.hu/twiki/bin/view/KFKIAFS/AfsSoftwares#GANGA][KFKI AFS]]. To activate it, follow the instructions of that homepage.

_Note2_: If your home directory is located on AFS, it is advised to source the following shell script before logging on to the Grid:
<verbatim>
## Make new .globus directory and export it:
chmod  -R  755  /tmp/$USER/globus  >&/dev/null
rm  -rf  /tmp/$USER/globus
mkdir  -p  /tmp/$USER/globus
cp  $HOME/.globus/usercert.pem  /tmp/$USER/globus/
cp  $HOME/.globus/userkey.pem  /tmp/$USER/globus/
cp  $HOME/.globus/certificates  /tmp/$USER/globus/
export  X509_USER_CER=/tmp/$USER/globus/usercert.pem
export  X509_USER_KEY=/tmp/$USER/globus/userkey.pem
export  X509_CERT_DIR=/tmp/$USER/globus/certificates
## Make new .glite directory and export it:
chmod  -R  755  /tmp/$USER/glite  >&/dev/null
rm  -rf  /tmp/$USER/glite
mkdir  -p  /tmp/$USER/glite
cp  -rd  $HOME/.glite/* /tmp/$USER/glite/
export  GLITE_USER_HOME=/tmp/$USER/glite
</verbatim> (for _bash_), or <verbatim>
## Make new .globus directory and export it:
chmod  -R  755  /tmp/$USER/globus  >&/dev/null
rm  -rf  /tmp/$USER/globus
mkdir  -p  /tmp/$USER/globus
cp  $HOME/.globus/usercert.pem  /tmp/$USER/globus/
cp  $HOME/.globus/userkey.pem  /tmp/$USER/globus/
cp  $HOME/.globus/certificates  /tmp/$USER/globus/
setenv  X509_USER_CER  /tmp/$USER/globus/usercert.pem
setenv  X509_USER_KEY  /tmp/$USER/globus/userkey.pem
setenv  X509_CERT_DIR  /tmp/$USER/globus/certificates
## Make new .glite directory and export it:
chmod  -R  755  /tmp/$USER/glite  >&/dev/null
rm  -rf  /tmp/$USER/glite
mkdir  -p  /tmp/$USER/glite
cp  -rd  $HOME/.glite/* /tmp/$USER/glite/
setenv  GLITE_USER_HOME  /tmp/$USER/glite
</verbatim> (for _tcsh_). This ensures that the necessary files are accessible even after your AFS tickets expire (as they are copied to some local directory). You could also put these inside a shell function or alias in your =.bashrc= or =.tcshrc=, like:
<verbatim>
### Function to export the grid stuff in $HOME to the /tmp/$USER:
exportlocal()
{
    # ... the above stuff comes here ...
}
</verbatim> (for _bash_), or
<verbatim>
### Alias to export the grid stuff in $HOME to the /tmp/$USER:
alias  exportlocal  \
# ... the above stuff comes here, but put ' ; \' instead of new line, and continue in next line ...
</verbatim> (for _tcsh_).

If your home is on AFS, it is also advised to move also your working directory under =/tmp/$USER=, together with all the necessary files and directories, described in the following sections. To prevent that the regular cleanup cron job deletes some of your files from =/tmp/$USER= when they are too old, run the command
<verbatim>
find  /tmp/$USER  -print  -exec touch {} \;
</verbatim> after unpacking the below tarballs into =/tmp/$USER=.

---+++ Simple job submission with traditional JDL files


---+++ Mass submission of independent jobs: parameter scan with short calculations


---+++ Mass submission of chained jobs: parameter scan with long calculations
