We’re putting the final touches on our new badges platform. Badge issuance remains temporarily paused, but all completions are being recorded and will be fulfilled once the platform is live. Thank you for your patience.

@partha.nakti,

Python API or Optimization (lumapi/lumopt) requires a GUI connection and will checkout a GUI license. See this KB for more info. GPU is only used when you run the simulation file (.fsp). 

Are you able to open the Lumerical FDTD CAD/IDE? 

/opt/lumerical/v232/bin/fdtd-solutions & 

How are you configuring your simulation and resources to use GPU when running the simulation?  (see KB for details) 

Which Linux distro and version are you on? 

cat /etc/*release

Which specific release of Lumerical 2023 R2 are you running? 

/opt/lumerical/v232/bin/fdtd-solutions -v 
/opt/lumerical/v232/bin/fdtd-engine -v

Looking forward to your reply.
