@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.
