Starting programs with a GUI on the nodes via the batch system

Running a program like Mathematica in the batch system, if the grafical user interface shall be used requires some additional steps.

• Reserve a node in the interactive mode with (replace project with your project's name and the variables according to your needs, second line is for one largesmp node)

qsub -I -A _project_ -l walltime=12:00:00,nodes=1:westmere:ppn=12 -q default -X
qsub -I -A _project_ -l walltime=12:00:00,nodes=1:ppn=32 -q largesmp -X

• Start the program
• After finishing the work with the program, exit the session you got from the batch system
• When using windows, you will need a local Xserver like Xming or login via vnc.
