In this paper, we present and analyze parallel substructuring methods based on conjugate gradient method, a iterative Krylov method, for solving sparse linear systems on GPUs. Numerical experiments performed on a set of matrices coming from the finite element analysis of large scale engineering problems, show the efficiency and robustness of substructuring methods based on iterative Krylov method...
Coons patch is important element in 3D modeling and simulation. In order to use general framework of GPU to constitute coons patches, one decompose method of the traditional coons patches was developed. The result shows that runtime of GPU based algorithm tend to increase slowly while the number of interpolation points increase.
The development of computational grid of the research institute of intelligent computer systems is described in this paper. The development of computational grid's hardware and software are presented. The performance experiments are done concerning the parallelization of artificial neural networks training implemented on the proposed grid architecture.
The video coding standard H.264 supports video compression with a higher coding efficiency than previous standards. However, this comes at the expense of an increased encoding complexity, in particular for motion estimation which becomes a very time consuming task even for today's central processing units (CPU). On the other hand, modern graphics hardware includes a powerful graphics processing unit...
The graphics processing unit (GPU) has become an integral part of today's mainstream computing systems. Over the past six years, there has been a marked increase in the performance and capabilities of GPUs. The modern GPU is not only a powerful graphics engine but also a highly parallel programmable processor featuring peak arithmetic and memory bandwidth that substantially outpaces its CPU counterpart...
