Abstract

Calculation efficiency of results double-wave X-ray reflectometry for multilayered structures on GPU with application of platform NVIDIA CUDA is considered. For the first time effective implementation of calculations on interpretation of the data relative double-wave X-ray reflectometry on the basis of technology CUDA is offered. In this paper comparison calculation speed of mathematical model on GPU NVidia GeForce 8500 GT with speed of calculation on the basis of the CPU Intel Core 2 Duo E6400 is spent. Experiments have shown, that calculations time of parameters for multilayered structures on GPU is reduced more than 10 times in comparison with calculation on the CPU.

Keywords:

Double-wave X-ray reflectometry, multilayered structures, efficiency of calculations, the CUDA technology on GPU
