How to run SimLab scripts in batch mode on HPC? 

Foremost the user needs to understand the use of ‘-nographics’ and ‘-headless’ in SimLab. 

The ‘-nographics’ argument will hide GUI and perform all graphical operations internally. When users use ‘-nographics’ a GUI should be available in the HPC. It will not work on a headless computer. 

The ‘-headless’ argument is used to run the SimLab commands on a non-GUI computer. This functionality is available from SimLab 2023. From this version, the users can use SimLab.bat -headless –auto script to submit the jobs. 

Suppose the users are using older versions of SimLab (pre-SimLab 2023). In that case, it is recommended to use Xvfb (X virtual frame buffer) or any other similar tool as an alternative.  

Kindly use the virtual buffer in the HPC server as follows, 

  1. Install Xvfb in the HPC.
  2. Run the command “Xvfb :99 &”
  3. Run the command, export DISPLAY=:99 
  4. Finally run SimLab.bat –auto your script.
