GUI Access

The CNM holds 2 GUI licenses (for running CAD), each with accompanying FDTD licenses, and 10 additional engine licenses.

There are two means to access Carbon's Lumerical licenses:

1. X11 forwarding.
2. License port forwarding.

X11 mode

Use the CAD X11 app on a Carbon login node.

CAD &

• Requires X11 forwarding under SSH.
• Disadvantage: May run slow or unstable.

Native

Run CAD natively on your desktop, but connect to the Lumerical license server on Carbon.

• Advantage: Native graphics speed.
• Caveat: needs an active network connection to a Carbon login node.

• We do not use the new-style LM: http://docs.lumerical.com/en/mode/install_fdtd_remote_access.html
• We do use the Legacy LM: http://docs.lumerical.com/en/mode/install_lumerical_license_manager.html#installation
  • Add to ~/.ssh/config:

…
Host clogin      # or similar
    LocalForward    26044 cmgmt3:26044
    …

• • In CAD, specify localhost as license server.

• • The setting is stored in ~/.config/Lumerical/FDTD\ Solutions.ini .
