Mapped Network Drive Configuration

Running Lumerical FDTD on CIRCE
The Lumerical FDTD user guide is essential to understanding the application and making the most of it. The guide and this page should help you to get started with your simulations. Please refer to the Documentation section for a link to the guide.
- Note on CIRCE: Make sure to run your jobs from your $WORK directory!
- Note: Scripts are provided as examples only. Your SLURM executables, tools, and options may vary from the example below. For help on submitting jobs to the queue, see our SLURM User’s Guide.
Below is an example of how to run FDTD Solutions on CIRCE using your S: drive and locally-installed FDTD Solutions software.
1. From your workstation, save your project to
2. Then, log into CIRCE via SSH and change your directory to ~/nanowire, which is the same directory that appears on your S: drive:
[user@login0]$ cd ~/nanowire [user@login0 nanowire]$
3. Next, create a script for your job, and submit it to SLURM.
- The script below (for testing, name it “lumerical-test.sh”) can be copied into your job directory (the folder with your input files) and modified so that you can submit batch processes to the queue.
#!/bin/bash # #SBATCH --comment=lumerical-test #SBATCH --ntasks=8 #SBATCH --job-name=lumerical-test #SBATCH --export=FSPFILE=nanowire.fsp #SBATCH --output=output.%j.lumerical-test #SBATCH --time=01:00:00 #### SLURM 8 processor Lumerical test to run for 1 hour. module purge module add apps/fdtd/8.5.3 module add compilers/intel/2013_cluster_xe mpirun fdtd-engine-impi-lcl $FSPFILE
4. Finally, you can change to your job’s directory, and run the sbatch command to submit the job:
cd my/job/directory sbatch ./lumcerical-test.sh
- You can view the status of your job with the “squeue -u <username>” command
- Once the simulation is complete, you can open S:\nanowire\nanowire.fsp from FDTD Solutions on your workstation to view the results.
