Hi Simulationlord,
we have many possibilities to optimize your scripts in NGSolve.
First important thing is to know where are your bottle-necks which you want to optimize.
What kind of problems are you solving ?
Do you use optimal solvers for your problems ?
What kind of parallelization are you using already ?
There is no explizit support of GPUs in the finite element part, but you may use GPU solvers e.g. via the PETSc interface.
