====== Mathematica ======

===== Description =====

Mathematica is a universal interactive computer algebra application system with advanced graphical user interface.

===== Lizence =====
On the HPC ressources at GWDG there are four network licences available for Mathematica.

===== Login =====

The dialog server and frontend nodes of the HPC ressources at GWDG can be reached directly only inside the GoeNet network.
Login to gwdu101 (or alternatively to gwdu102) via:

''ssh -Y gwdu101''

For the connection from Microsoft clients use an appropriate software like X-Win32. 

If your connection to gwdu101 is refused you might not have the permission to use the HPC ressourcen. You can request this permission by a short email to [[mailto:hpc@gwdg.de]].

If you want to use the service from outside GoeNet, first login to login.gwdg.de and then proceed as above.

===== Command =====

First prepare the necessary environment with:

''module load mathematica''

The use of Mathematica then will be scheduled by the batch system in the interactive queue onto a free ressource. Therefore the following command  to the batch system is necessary:

''bsub -ISs -XF -q int /bin/bash''

after a short time period you will get a Shell prompt and you can call Mathematica in the command line version with the command:

''math''

or in the X11 window version with the command:

''mathematica''

The current version is printed as the first line of the output.
