Adaptive Sequential Posterior Simulators for Massively Parallel Computing Environments
free download
ABSTRACT Massively parallel desktop computing capabilities now well within the reach of individual academics modify the environment for posterior simulation in fundamental and potentially quite advantageous ways. But to fully exploit these benefits algorithms that
MiniGhost: a miniapp for exploring boundary exchange strategies using stencil computations in scientific parallel computing
free download
ABSTRACT A broad range of scientific computation involves the use of difference stencils. In a parallel computing environment, this computation is typically implemented by decomposing the spacial domain, inducing a halo exchange of process-owned boundary data. This
Massively-Parallel Computing on Cog ex Machina
free download
ABSTRACT Cog ex Machina is a software framework for building massively-parallel applications on commodity, multicore hardware. Complex models may be expressed in a simple,Abstract programming model, while hiding the complexities (threads, locks,
Re-Optimizing data-parallel computing
free download
Abstract Performant execution of data-parallel jobs needs good execution plans. Certain properties of the code, the data, and the interaction between them are crucial to generate these plans. Yet, these properties are difcult to estimate due to the highly distributed
Point to point processing of digital images using parallel computing
free download
ABSTRACT This paper presents an approach the point to point processing of digital images using parallel computing, particularly for grayscale, brightening, darkening, thresholding and contrast change. The point to point technique applies a transformation to each pixel on
The Assessment of Bandwidth Requirements for Meteorological Code VARSHA on a Parallel Computing System
free download
ABSTRACT Complex scientific problems like weather forecasting, computational fluid and combustion dynamics, computational drug design etc. essentially require large scale computational resources in order to obtain solution to the equations governing them.
Parallel Computing System for Image Intelligent Processing
free download
ABSTRACT In this paper, a parallel computing system for image intelligent processing is described. This parallel computing system includes two main parts: A parallel computer and a set of software tools. The parallel computer is constructed by a host processor, a SII\/ID
The boat hull model: adapting the roofline model to enable performance prediction forparallel computing
free download
Abstract Multi-core and many-core were already major trends for the past six years, and are expected to continue for the next decades. With these trends of parallel computing, it becomes increasingly difficult to decide on which architecture to run a given application. In
PC-based real-time video watermark embedding system independent of platform for parallel computing
free download
An improved system is described for embedding watermarks into video frames in real time using software running on an ordinary personal computer and that is independent of the parallel-computing platform. It uses standard video I/O and is separate from the encoding
Parallel and Distributed Computing and Systems
free download
Purpose Exploring parallelism and concurrency is an efficient way of sharing interconnected processing and data resources to speed up time critical computation, lower costs of design and production, increase profit, create a better business environment, and improve
Computing A Matrix Transpose of Multithreading for Queueing Parallel in Matlab Programming
free download
ABSTRACT This paper describes a A matrix operation (vector and transpose) can be performed in queueing parallel model by using multithreading software are showing. Multithreading is useful in reducing the latency by switching among a set of threads in
Vortex particle method and parallel computing
free download
In this paper, it was presented numerical results related to three dimensional simulation of motion of a vortex ring. For the simulation it was chosen the Vortex In Cell method. The method was shortly described in the paper. The numerical results were obtained on the
Towards user transparent parallel multimedia computing on GPU-clusters
