NVIDIA and AMD GPUs are are gaining traction in HPC for their performance and architectural aspects. It is very important to measure and analyze the relative power of each architecture. In this paper, we analyze the architecture of NVIDIA’s Fermi and AMD’s Evergreen processors and demonstrate the best practices and techniques to best utilize the […]

EMI engineers are struggling everyday with complex radiation problems that fails critical products to pass EMI certification and causes big loss of profit. Advances in EMI engineering are following a similar trend like Signal-Integrity engineering 10-years ago when tools nowadays became capable of providing accurate predictive simulations in a reasonable amount of time. With careful […]

The interest in immersive 3D video conference systems exists now for many years from both sides, the commercialization point of view as well as from a research perspective. Still, one of the major bottlenecks in this context is the computational complexity of the required algorithmic modules. This paper discusses this problem from a hardware point […]

The paper presents a numerical reconstruction method of digital holography based on graphic processing unit with MATLAB, which can obtain a calculation speed about 41 times faster than a CPU alone and make real-time system possible.

Modeling low current electron beams with high accuracy presents a number of novel challenges to existing simulation tools. For applications that use currents of the order of microamperes, such as electron beam lithography, nanolithography, electron microscopy and quality inspection, it is necessary to simulate ensembles of individual electrons to account correctly for the statistical effects […]

Recently, a number of cloud computing paradigms have been proposed. The new term of cloud computing is not a new concept, is a long-held dream of computing as a utility [1]. From the view of datacenters, the common understanding of the cloud computing concept is Software as a Service (SaaS), utility computing and application virtualization. […]

Recent advances in graphics computing technology has brought highly parallel processing power to personal computers. This paper reports a hardware-accelerated symmetrical condensed node TLM procedure for the NVIDIA graphics processing units. The procedure has been tested on three NVIDIA processors, from laptop graphics card to workstation graphics processors.

Multiple-precision integer operations are key components of many security applications; but unfortunately they are computationally expensive on contemporary CPUs. In this paper, we present our design and implementation of a multiple-precision integer library for GPUs which is implemented by CUDA. We report our experimental results which show that a significant speedup can be achieved by […]

In this paper, we present a simple and practical technique for real-time rendering of caustics from reflective and refractive objects. Our algorithm, conceptually similar to shadow mapping, consists of two main parts: creation of a caustic map texture, and utilization of the map to render caustics onto nonshiny surfaces. Our approach avoids performing any expensive […]

Given the depth and breadth of the field of interactive rendering, an article summarizing all the significant algorithms and hardware developments in the past few years would become a long yet shallow litany of taxonomies and terms. Instead, the author uses a selection of topics from various areas to illustrate this central theme: the influence […]

In this paper we modify a fast heuristic solver for the Linear Sum Assignment Problem (LSAP) for use on Graphical Processing Units (GPUs). The motivating scenario is an industrial application for P2P live streaming that is moderated by a central node which is periodically solving LSAP instances for assigning peers to one another. The central […]

We report on our implementation of the RHMC algorithm for the simulation of lattice QCD with two staggered flavors on Graphics Processing Units, using the NVIDIA CUDA programming language. The main feature of our code is that the GPU is not used just as an accelerator, but instead the whole Molecular Dynamics trajectory is performed […]
