== Access and user environment ==
'''idefix''' can be accessed via:
{{{
ssh -X replace_by_your_idefix_username@idefix.muk.uni-hannover.de  or
ssh -X replace_by_your_idefix_username@130.75.105.239
}}}

Create an ssh key on your local PC, and copy it to idefix using the command:\\\\
{{{
ssh-copy-id -i replace_by_your_local_path_to/.ssh/id_dsa.pub replace_by_your_idefix_username@130.75.105.239
}}}

In your $HOME directory, add lines
{{{
export LD_LIBRARY_PATH=/opt/netcdf4_hdf5parallel/4411c_443f/intel/lib:$LD_LIBRARY_PATH
ulimit -s unlimited
}}}
to file {{{.myprofile}}} (create if it doesn't exist).

== Installation of PALM ==
To download and install the latest PALM version, follow the first steps of the [https://palm.muk.uni-hannover.de/trac/wiki/doc/install/advanced#Packageinstallation advanced installation procedure] as described on the PALM website. The [https://palm.muk.uni-hannover.de/trac/wiki/doc/install/automatic automatic installer] will be available soon. Following steps also need to be carried out and are slightly different to those described on the PALM website. With the automatic installer, the following steps will be carried out automatically. The [https://palm.muk.uni-hannover.de/trac/wiki/doc/app/mrungui mrungui] does not run on idefix at the moment.

(1) To use the PALM scripts, the {{{PATH}}}-variable has to be extended and the environment variable {{{PALM_BIN}}} has to be set in the respective profile of the users default shell (e.g. {{{.myprofile}}}:
{{{
  export PATH=$HOME/palm/current_version/trunk/SCRIPTS:$PATH
  export PALM_BIN=$HOME/palm/current_version/trunk/SCRIPTS
}}}
You may have to login again in order to activate these settings.\\\\

(2) Copy '''idefix'''-specific mbuild/mrun configuration file (available from r2202) to your working directory:
{{{
cp $HOME/palm/current_version/trunk/SCRIPTS/.mrun.config.idefix $HOME/palm/current_version/.mrun.config
}}}
Besides many other things, this file contains typical installation parameters like compiler name, compiler options, etc. In this file, enter your '''idefix''' user name at locations ''<replace_by_your_IDEFIX_username>''.\\\\
'''Warning: When editing the configuration file, please NEVER use the TAB key. Otherwise, very confusing errors may occur when mrun is executing.'''\\\\

(3) Compilation of utilities and source code:
After modifying the configuration file, the respective executables are generated by executing
{{{
  mbuild -u -h lcidefix
}}}
Pre-compile the PALM code by
{{{
  mbuild -h lcidefix
}}}

(4) Installation verification: Follow the steps of the [https://palm.muk.uni-hannover.de/trac/wiki/doc/install/advanced#Installationverification verification procedure] as described on the PALM website.
