Mathematica is a computational software program used in many scientific, engineering, mathmatical and computing fields.

Starting Mathematica on COSMOS

Mathematica is gui based and likely to consume significant resources such as CPU time and/or memory. Resource intensive Mathematica sessions must not be started on the login nodes. We recommend starting Mathematica as an on-demand application using the graphical application launcher.
You get a gui similar to:

Mathematica in the GfxLauncher

  • Adjust the walltime to your needs. The session will be terminated once the requested time has elapsed. Do not request excessive amounts of time, if you do not manually terminate the sesssion and the session keeps running, your project gets charged for the full time.
  • Due to licensing issues, do not utilise more than 4 tasks, which is the default setting.
  • Choose the relevant project
  • Press start. The Mathematica gui will start once resources are available. This might take a moment or two.


LUNARC does not have a Mathematica license. To use Mathematica on COSMOS, you have to bring your own license. Assuming your license is held on a MathLM or equivalent license server the Mathematica gui can be utilised to connect to the license server. On launch you get the following screen:

Mathematica Product Activation Window

Select: Other ways to activate

Mathematica Activation Method

Select: Activate through a Wolfram network license server

Enter the address of your license server into the next window and press activate. You have to obtain the address of your license server from the manager of your Mathematica license. LUNARC does not know this.
