Error with lumerical license activation.

aadityaaaditya Member Posts: 1

Hello,

I am a Ph.D. student at USC and want to use Lumerical FDTD for simulations. We have purchased an ANSYS Academic Lumerical Research (1 task). The High Performance Computing has installed the license manager and the software for our use on USC supercomputer cluster, but we are not able to run simulations . On submitting a job I get the following error:

Due to MODULEPATH changes, the following have been reloaded:

 1) pmix/3.1.3


a02-26.hpc.usc.edu(process 0): Error: Unable to obtain a node locked or floating license. Either activate a node locked license or enter the address for your floating license server. Please see the <a href=https://kb.lumerical.com/redirect/fwd3.html>Troubleshooting guide</a> for help resolving this issue.<p><b>Floating error: -97</b> The desired vendor daemon is down.

 Check the lmgrd log file, or try lmreread.

Feature:    FDTD_Solutions_engine

Vendor:Host:  hpc-dns

License path: 1055@hpc-dns:

Would you like to reconfigure your license settings?, Response: No

    @aaditya Please make sure the port for the ansyslmd daemon is open on the license server firewall. Starting with 2021R1 the applications must communicate through ansyslmd and lmgrd.


    You can set ansyslmd to a static port by adding it in the license file on the VENDOR line.


    For example:

    VENDOR ansyslmd PORT=1056


    From the client machine where you are trying to run Lumerical, please try to telnet to the license server on the 2 licensing ports to confirm connectivity. To test the access, you can use one of these options, please try for the lmgrd port and ansyslmd port, modify the command to replace "192.168.0.1" with the license server hostname.


    Telnet 192.168.0.1 1055


    nc -v -z -w2 192.168.0.1 1055


    (echo >/dev/tcp/192.168.0.1/1055) &>/dev/null && echo "Open 1055" || echo "Close 1055"

    Just to add, your error message indicates that you are trying to checkout a license feature that is not on your license server,

    Feature:   FDTD_Solutions_engine
    Vendor:Host: hpc-dns
    License path: 1055@hpc-dns:
    

    You will need Lumerical/FDTD version 2021 R1 to be able to checkout the license from your Ansys license server, 1055@hpc-dns. And configure Lumerical to obtain the license from Ansys (standard) LM.

    If you do not have GUI access to the cluster, set the license configuration as shown in this article. Where domain=2 for the Ansys (Standard) license server.

    Best,

    Lito
