Double-gyre ocean circulation is a typical phenomenon in the northern mid-latitude ocean basins. Its low-frequency variability significantly influences on both ocean and climate. To enhance its predictability, the finding of optimal initial perturbation which can trigger the double-gyre variation is important. CNOP method is adopted to calculate the optimal initial perturbation and this method has...
Recent development and popularity of Flash Memory requires efficient error correction technique on its eco system like gaming and mobile platforms. In this paper, we have addressed an efficient method to decode and correct errors using the parallel computing technique offered by Graphical Processing Unit (GPU). This decoder employs the inversion-less Berleykamp-Massey algorithm (iBMA), and Chein search...
Modern GPUs (Graphics Processing Units) offer very high computing power at relatively low cost. Nevertheless, designing efficient algorithms for the GPUs usually requires additional time and effort, even for experienced programmers. On the other hand, tridiagonal systems solvers are an important building block for a wide range of applications. In this paper, we present a new tuning parallel proposal...
During the past decade Graphics Processing Units (GPU) have been increasingly employed for speeding up compute intensive scientific applications. In this field, the geometric multigrid method (GMG) is one of the most efficient algorithms for solving large sparse linear systems of equations. Herein we analyze the performance of an optimized GPU based implementation of the GMG method on different state-of-the-art...
Three-dimensional geological model can describe the types of geological information, and express a variety of topological relations among geological phenomena. Kriging interpolation is an important spatial interpolation method of geological modeling, but every grid point needs to compute augmented matrix and solve equations. With the modeling scale and bore data quantity increasing rapidly, we propose...
We introduce a basket option pricing problem arisen in financial mathematics. We discretized the problem based on the alternating direction implicit (ADI) method and parallel cyclic reduction is applied to solve the set of tridiagonal matrices generated by the ADI method. To reduce the computational time of the problem, a general purpose graphics processing units (GP-GPU) environment is considered...
We present and compare implementations of an affine interior-point algorithm for real-time collision detection on a GPGPU and an FPGA. This particular interior-point algorithm is distinguished from other collision detection methods by its ability to perform detection between pairs of objects undergoing fast rotational and translational movement. This enables inter-frame collision detection, i.e. collision...
