Dispersive Möbius Transform Finite-Element Time-Domain Method on Graphics Processing Units

Accelerating the Hough Transform with CUDA on Graphics Processing Units

Circle detection has been widely applied in image processing applications. Hough transform, the most popular method of shape detection, normally takes a long time to achieve reasonable results, especially for large images. Such performance makes it almost impossible to conduct real-time image processing with sequential algorithms on community computers. Recently, NVIDIA developed CUDA programmi...

Cofactorization on Graphics Processing Units

We show how the cofactorization step, a compute-intensive part of the relation collection phase of the number field sieve (NFS), can be farmed out to a graphics processing unit. Our implementation on a GTX 580 GPU, which is integrated with a state-of-the-art NFS implementation, can serve as a cryptanalytic co-processor for several Intel i7-3770K quad-core CPUs simultaneously. This allows those ...

Graphics processing unit–accelerated finite-difference time-domain method for characterization of photonic crystal fibers

In the work, we have presented the technique based on the graphics processing unit accelerated finite-difference time-domain (FDTD) method for characterization of a single-mode photonic crystal fiber (PCF) with an arbitrary refractive index profile. In contrast to other numerical methods, the FDTD allows studying the mode propagation along the fiber. Particularly, we have focused attention on t...

Real-Time SAR Simulation on Graphics Processing Units

SAR simulators usually apply the ray-tracing approach. Ray-tracing, which is also used for virtual image generation, is based on accurate physical models, but is unfortunately rather computational time intensive. Because of this, real-time applications, like interactive visualisation, in general use the rasterization method. Rasterization is less complex to calculate and is therefore faster. Th...
