指導教授 : 許文翰

摘要


本論文在交錯網格上發展三維時域有限差分法(FDTD),以求解馬克斯威爾方程。 本文的方法是執行於資料相依度不高的網格上,非常適合進行平行計算。 平行計算的平台使用多核心中央處理器(CPU)和最近發展迅速的圖形處理器(GPU)。 為了達到速度提升的目的,本文所提出的資料結構屬於共享記憶體的方法,它能有效的減少對於資料於存取時的延遲,而得以顯著地提升計算效能。

An explicit finite-difference scheme for solving the three-dimensional Maxwell's equations using CPU/GPU platform is presented in time domain. Computational performance will be assessed based on the results obtained from the calculation in Nvidia Tesla K20(GPU) and in I7-4820K CPU. This thesis develop a method that get good speedup by using shared memory. Final we simulate a photonic crystals waveguide converter problem to prove this program correctness.
