a r t i c l e i n f o a b s t r a c t We present a CPU–GPU system for runtime acceleration of large molecular simulations using GPU computation and memory swaps. The memory architecture of the GPU can be used both as container for simulation data stored on the graphics card and as floating-point code target, providing an effective means for the manipulation of atomistic or molecular data on the...

In this paper, we introduce a graphic processing unit (GPU)-based framework for simulating particle trajectories under both static and dynamic force fields. By exploiting the highly parallel nature of the problem and making efficient use of the available hardware, our simulator exhibits a significant speedup over its CPU-based analog. We apply our framework to a specific experimental simulation...

Effectively exploiting the resources available on modern multicore and manycore processors for tasks such as large vocabulary continuous speech recognition (LVCSR) is far from trivial. While prior works have demonstrated the effectiveness of manycore graphic processing units (GPU) for high-throughput, limited vocabulary speech recognition, they are unsuitable for recognition with large acoustic...

We present a new implementation of the numerical integration of the classical, gravitational, N -body problem based on a high order Hermite’s integration scheme with block time steps, with a direct evaluation of the particle-particle forces. The main innovation of this code (called HiGPUs) is its full parallelization, exploiting both OpenMP and MPI in the use of the multicore Central Processing...

High performance computing (HPC) presents a technology that allows solving high intensive problems in a reasonable period of time, and can offer many advantages for large applications in various fields of science and industry. Current multi-core processors, especially graphic processing units (GPUs), have quickly evolved to become efficient accelerators for data parallel computing. They can mai...

1. Abstract This work presents the implementation of a topology optimization approach based on level set method in massively parallel computer architectures, in particular on a Graphics Processing Unit (GPU). Such architectures are becoming so popular during last years for complex and tedious scientific computation. They are composed of dozens, hundreds, or even thousands of cores specially des...

Many studies, even those conducted in the field of Americas, still argue that graphic communication necessarily builds on coding units speech. However, recent years, there has been a growing awareness narrowness this concept by focusing Indigenous and pre-Columbian societies, who favore(d) non-glottographic systems over written This paper concerns development semiological multidimensional theor...

The real-time display of full-range, 2048?axial pixelx1024?lateral pixel, Fourier-domain optical-coherence tomography (FD-OCT) images is demonstrated. The required speed was achieved by using dual graphic processing units (GPUs) with many stream processors to realize highly parallel processing. We used a zero-filling technique, including a forward Fourier transform, a zero padding to increase t...

The Smith-Waterman (SW) algorithm has been widely utilized for searching biological sequence databases in bioinformatics. Recently, several works have adopted the graphic card with Graphic Processing Units (GPUs) and their associated CUDA model to enhance the performance of SW computations. However, these works mainly focused on the protein database search by using the intertask parallelization...
