My research team is planning to run a large number of simulations( 1000s) to generate data for a possible machine learning project. We have created a square slab of material and etched a cut into it. In the simulations, we want to change the shape, size, and location of the cut and compute the reflectance of the material. We have access to Argonne National Lab and can use a large number of nodes to run many simulations at once.
I have created a python script that can create the simulation input file and another which can extract the data once the simulation is finished. I wonder if we can automate the process of submitting all the jobs at once.
Also, is using varFDTD going to be more useful here if the structure can be made into 2D?
Answer to these questions will be very helpful.
AnikeyaJuly 8, 2021 at 7:15 pmGuilin SunAnsys EmployeeHi, Anikeya Lumerical has the capacity of distributed and concurrent parallel simulations. Since you want to simulate many different files in a larger cluster, you have 2 options:
1: create all the files, and add them in the job quque. related script commands are
addjob - Script command
runjobs - Script command
clearjobs - Script command
Before you run them concurrently, please set to use all the nodes.

July 9, 2021 at 5:23 pmaadityaSubscriberThanks, gsun. I will take a look at these. Is it possible to run over 1000 simulations from different input files at the same time on 1000 or more nodes?
July 9, 2021 at 5:29 pmGuilin SunAnsys EmployeeAs long as you have enough license, or cloud license, it should be ok. Please refer Cluster Licensing ÔÇô Lumerical Support or contact us by email if you have premium support.
July 9, 2021 at 5:53 pmaadityaSubscriberWe have a floating license . ANSYS Academic Lumerical Research (1 task)
July 9, 2021 at 7:15 pmLito YapAnsys EmployeeFor ANSYS academic or teaching licenses, support is provided here in the forum.
To add, 1 solve/engine license can run 1 simulation job up to a maximum of 32 cores. So to run 1000 simulation files at the same time (concurrent) using 32 cores each, you will need 1000 solve/engine licenses. See this article in our KB for more information.
