  I want to run the the ansys example of optimizing a 2d grating coupler on a linux cluster.
  https://optics.ansys.com/hc/en-us/articles/360042800573-Inverse-Design-of-Grating-Coupler-2D-
  But I can't find any good guidance as to how you execute the python script. It would be nice if someone could guide me to where I can find some info on running optimization scripts on a cluster.

  Hi Nicholei,
  The optimization or API scripts are part of our CAD/GUI environment and are run from the Lumerical CAD/GUI and will take up a GUI license to run.
  >>> Lumerical product components and licensing overview – Ansys Optics
  This will require a GUI connection on the cluster to open the CAD and run the scripts.
  >>> Lumerical job scheduler integration configuration (Slurm, Torque, LSF, SGE) – Ansys Optics
  >>> Job scheduler submission scripts (SGE, Slurm, Torque) – Ansys Optics
  Consult with your IT/cluster admins to run the Lumerical CAD/GUI on your cluster for running Lumerical optimzations/scripts.
  Check out our Knowledge Base (KB) for more information on running Lumerical on HPC or on premise clusters.
