On your desktop or laptop, do the following: Reminder: Licensing for all Lumerical applications running on Carbon itself (i.e., as started on a login node or by a batch job) are pre-configured, so none of the following applies there. When inside CNM or using VPN as a CNM staff member or postdoc The specific configuration steps depend on the network location of your computer, as follows:
Your Lumerical suite must be configured to use those license servers.Your computer must be able to reach the Carbon license server, at least while you run any of the Lumerical applications.To use the #Native Lumerical applications on your computer, as opposed to running on Carbon over a graphical connection, the following conditions must be met: Transfer any updated *.fsp files back from Carbon to your machine, if so desired, for analysis there.Ĭonfiguring license access when not running on Carbon directly.Await job completion, either by inspection, or by receiving a job completion mail.Copy and adapt one of the Carbon Lumerical job templates for your model.Transfer the file to Carbon (if you did the above steps on your machine).For a parameter sweep: define your parameter grid, i.e., the variables, search intervals, and number of variable steps.Running a sweep on Carbon allows you to process the grid points of your parameter mesh in parallel over the CPUs on one compute node or even on several compute nodes. Select this means when the compute task runs for a longer time, or you have many compute tasks, in particular when you run a "parameter sweep". Select this means when you expect the compute task to complete relatively quickly – say, up to an hour or so, or however long you can tolerate to dedicate CPU on your machine. Ways to run Lumerical compute engine applicationsįor the compute engine, there are two distinct ways to run: Disadvantage: Limited desktop environment, Copy&Paste support depends on VNC viewer client.Advantage: uses compression and hence can be faster than X11.Run "fdtd-solutions" on Carbon in a VNC virtual desktop, and view this virtual desktop on your machine. Advantage: Runs with its own windows, has basic Copy&Paste support.Requires an X11 server application on your desktop machine.
Run "fdtd-solutions" as an X11 application on a Carbon login node, and have its windows appear on your screen. In the application, configure license access as shown below.
