GPU Accelerated Computation and Real-time Rendering of Cellular Automata Model for Spatial Simulation

Because Cellular Automata (CA) is a dynamic system with inherent parallelism, many studies are focused on mapping CA to the parallel system in order to obtain high performance computing capability, such as using clusters, supercomputers and networks of computers. But the application of these systems are too expensive and difficult to use on the occasions […]

Effect of GPU Communication-Hiding for SpMV Using OpenACC

In the finite element method simulation we often deal with large sparse matrices. Sparse matrix-vector multiplication (SpMV) is of high importance for iterative solvers. During the solver stage, most of the time is in fact spent in the SpMV routine. The SpMV routine is highly memory-bound; the processor spends much time waiting for the needed […]

Graphics Processing Unit Bloom Filters: Classical and Probabilistic

Graphics Processing Units (GPUs) have been used to enhance the speed and efficiency of both data structures and algorithms alike. A common data structure used in Computer Science is the Bloom Filter, which is used in many types of applications including databases and security logging. The Bloom Filter is a lossy data structure that uses […]

Non-Local Total Generalized Variation for Optical Flow Estimation

In this paper we introduce a novel higher-order regularization term. The proposed regularizer is a non-local extension of the popular second-order Total Generalized variation, which favors piecewise affine solutions and allows to incorporate soft-segmentation cues into the regularization term. These properties make this regularizer especially appealing for optical flow estimation, where it offers accurately localized […]

GPU-SPARC: Accelerating Parallelism in Multi-GPU Real-Time Systems

GPU (General-Purpose computation on Graphics Processing Units) offers an effective computing platform to accelerate a wide class of data-parallel computing. Multi-GPU’s appear as an attractive platform to speed up the computation of data-parallel GPU. This paper aims to explore the feasibility of relaxing the task-level restriction of single GPU use in multi-GPU real-time systems.We develop […]

Accelerating Fruchterman-Reingold with OpenCL

Twilight, an interactive multi-touch graph visualization research tool jointly developed by the University of Amsterdam and SURFsara, uses the Fruchterman-Reingold algorithm (amongst others) to create meaningful layouts for graphs. The required time for this algorithm to complete scales exponentially with the size of the graphs, therefore rendering large graphs quickly becomes impractical. To combat this […]

MPI-GIS: New Parallel Overlay Algorithm and System Prototype

Polygon overlay is one of the complex operations in computational geometry. It is applied in many fields such as Geographic Information Systems (GIS), computer graphics, VLSI CAD, etc. We have two significant results to report. Our first result is the first output-sensitive CREW PRAM algorithm for simple polygons, which can perform typical set operations including […]
