We have an exciting announcement about badges coming in May 2025. Until then, we will temporarily stop issuing new badges for course completions and certifications. However, all completions will be recorded and fulfilled after May 2025.

@Vighnesh Natarajan, 

I am sorry to hear that you are having issues running Lumerical simulations on your cluster. To debug/troubleshoot the issue: 

  • What is the operating system and version running on the cluster? 
  • Which Lumerical product/solver are you running? FDTD, MODE, CHARGE, HEAT, or INTERCONNECT?  
  • How are you running the simulation job? Are you using a job scheduler submission script and running this from the Terminal on the cluster head/login node? 
  • What is the job scheduler on your cluster - if you are using one? 
  • Please paste the execution line on the submission script or the command you run on the cluster, if you are not submitting to a job scheduler.
    (e.g. running FDTD with bundled MPICH2)
/install_path/lumerical/v222/mpich2/nemesis/bin/mpiexec -n 32 /install_path/lumerical/v222/bin/fdtd-engine-mpich2nem -t 1 /path_to/simulationfile.fsp
