abstract: |
In this dissertation, a Poisson solver is improved with three parts: the efficient
integrated Green's function; the discrete cosine transform of the efficient integrated
Green's function values; the implicitly zero-padded fast Fourier transform for charge
density. In addition, the high performance computing technology is utilized for the
further improvement of efficiency, such as: OpenMP API, OpenMP+CUDA, MPI, and MPI+OpenMP
parallelizations. The examples and simulation results are matched with the results
of the commonly used Poisson solver to demonstrate the accuracy performance.
