In this paper, an in situ power analysis profiling over time for general purpose graphics processing units (GPGPU) is presented. Based on this method the power consumption of different modes of operations like data transfer between GPU and host CPU, basic single precision floating point arithmetic operations (addition, subtraction, multiplication) on the multiprocessor units and instructions for shared...
Simulations of light scattering from nano-structured surface areas require substantial amount of computing time. The emergence of general purpose graphics processing units (GPGPUs) as affordable PC SIMD arithmetic coprocessors brings the necessary computing power to modern desktop PCs. In this paper we examine how the computation time of the finite-difference time-domain (FDTD), a classic numerical...
Modern massively parallel graphics cards (GPGPUs) offer a promise of dramatically reducing computation times of numerically-intensive data-parallel algorithms. As cards that are easily integrated into desktop PCs, they can bring computational power previously reserved for computer clusters to the office space. High performance rates make GPGPUs a very attractive target platform for scientific simulations...
In order to characterize nanostructures and nanosurfaces in production processes, measuring methods based on light scattering gain increasing importance. Thus the simulation capability of laser light scattering on surfaces with a size of several hundred or thousand wavelenghts in diameter and light scattering models on the nanometer scale are required to validate these new measurement techniques....
