|Full list of SHARCNET supported software|
As of February 2013, SHARCNET no long holds the FDTD Solutions (also known as front end or GUI) licence. Users who need to use FDTD Solutions for their model construction and data analysis must obtain their own licences.
Thanks to the kind donation of FDTD Engine licences by Lumerical solutions, Inc., SHARCNET will continue to support the serial farming and parallel processing of FDTD simulations on SHARCNET systems.
The latest release is 8.5.3 and this is the only version supported. The licences to the older versions have expired.
Note the FDTD engines are the only components that are supported. We no longer have the licence for the frontend FDTD Solutions.
It is assumed that users prepare their simulation files on their own computers with FDTD Solutions and then carry on large scale simulations--being large number of cases or large size of problems that are not feasible on their computers--on SHARCNET systems through serial farming or parallel processing. Typically this will involve transferring simulation files to SHARCNET and copying computed results back to their local computers for analysis.
To transfer data between one's computers and SHARCNET systems, one may use the common secure file transfer client software such as SSH Secure File Transfer Client, WinSCP, putty-sftp, etc. Users are referred to the tutorials on using these tools.
Loading Lumerical and Support Library Modules
Before you can run Lumerical, you must load the Lumerical module:
module load lumerical
As well one must perform the following
module unload openmpi intel compile module load gcc/4.3.4 module load openmpi/gcc/1.4.2
Before You Go The First Time
Before you run Lumerical simulations for the first time, remove the existing configuration file in your home directory, if any:
cd ~/.config rm FDTD\ Solutions.ini
This cleans the cached or corrupted Lumerical licencing infomation for previous versions.
Using FDTD Solutions GUI CAD
As of February 2013, SHARCNET no longer has the licence to the front end GUI (CAD for Linux).
Submitting A Serial Job
One must load necessary modules before submitting a job. Loading a module sets the environment variables needed for the running executables. The environment variables set will be inherited on the compute nodes automatically
module load lumerical sqsub -q serial -r 1.5h output%J fdtd-engine-mpich2nem simulation.fsp
Submitting A Parallel Job
Starting with version 7 the lumerical module must be loaded first before submitting a job or running the CAD command for instance as follows:
module load lumerical sqsub -q mpi -r 1.5h -n num_procs -o output%J fdtd-engine-ompi-lcl parallel_simulation.fsp
For further details about Distributed simulation testing please refer to the documentation on Lumerical's web site which can be found here.
