General-purpose computing on graphics processing units (GPGPU) is popular computing technology to utilize in various fields. In the paper, we parallelize cryptographical hash processing of a password cracking tool, John the Ripper, by utilizing CUDA on GPGPU. We also evaluate our work to compare the processing time of hash processing parallelized by GPU with that of the John the Ripper on a dual-core...
A GPGPU-based collision detection algorithm is proposed. Firstly, the information of OBB hierarchy tree and triangles of tested objects are mapped into some data textures designed for GPGPU-based calculation, such as triangle vertex textures, bounding box size texture, tree node relationship texture, etc., then these textures are downloaded to GPU to complete the data preparation. Secondly, the whole...
In this paper, we present a comparison study about implementations of phase correlation function using GPUs, ASIC and FPGAs. The Phase Only Correlation(POC) method demonstrates high robustness and subpixel accuracy in the pattern matching and the image registration. However, there is a disadvantage in computational speed because of the calculation of 2D-FFT etc. We have proposed a novel approach to...
This paper reports on our experience with data structure design for systems having both multiple CPU cores and a programmable graphics card. We integrate our data structures into the game-like application OpenSteerDemo and compare our data structures on two pc-systems. One System has a relative fast single core CPU and slower GPU, whereas the other one uses a high-end GPU with a slower multi core...
