Thank you, Lito.
What is the difference between:
fdtd-engine-ompi-lcl
and
fdtd-solutions
please?
(We want distributed computing instead of parallel computing, multiple processors performing one just one job.)
What is the command for running: fdtd-solutions, please?
The command for running: fdtd-engine-ompi-lcl is:
mpirun -np $SLURM_NTASKSfdtd-engine-ompi-lcltest.fsp

"fdtd-solutions" is the CAD/GUI component of FDTD. This is run/executed from your Desktop/Graphical environment which requires a GUI/graphical connection on the Linux machine. Typically on clusters, you do not have GUI access/graphical connection. You run the simulation file from the command prompt using the solver/engine component of FDTD.
cd /path_of_your_simulation_file/
module load openmpi #load your OpenMPI
mpirun /opt/lumerical/v221/bin/fdtd-engine-ompi-lcl -t 1 yoursimulationfile.fsp
