In this paper we present a novel technique to accelerate reconfigurable video coding with parallel architectures. We focus on the use of the Graphics Processing Unit (GPU) as our platform for parallel processing but the algorithm can be implemented on other parallel architectures. Implementation of the solution shows that execution time is reduced 16-60% depending on the decoder module implemen...

The latest advancements in computer graphics architectures, as the replacement of some fixed stages of the pipeline for programmable stages (shaders), have been enabling the development of parallel general purpose applications on massively parallel graphics architectures (Streaming Processors). For years the graphics processing unit (GPU) is being optimized for increasingly high throughput of m...

We present a parallel implementation of Schönhage’s integer GCD algorithm on distributed memory architectures. Results are generalized for the extended GCD algorithm. Experiments on sequential architectures show that Schönhage’s algorithm overcomes other GCD algorithms implemented in two well known multiple-precision packages for input sizes larger than about 50000 bytes. In the extended case t...

Networks of workstations (NOWs) are cost-effective alternatives to multiprocessor systems. Recently, NOWs have been proposed for parallel query processing. This paper explores the various architectures for using NOWs for parallel query processing. We start our discussion with two basic architectures: centralized and distributed. We identify the advantages and disadvantages associated with these...

The capabilities of switched networks for parallel and distributed computers are evolving rapidly towards networks with various forms of intelligence in support of parallel execution of programs. This paper presents a perspective on intelligent networks, including reconfiguration of the network to adapt to the needs of successive computational algorithms being performed as part of an overall pr...

New parallel architectures, such as Cell, Intel MIC, GPUs, and tiled architectures, enable high performance but are often hard to program. What is needed is a bridge between high-level programming models where programmers are most productive and modern parallel architectures. We propose that that bridge is Embedded Domain Specific Languages (EDSLs). One attractive target for EDSLs is Intel ArBB...

Experiments were conducted at NASA Ames Research Center t o define multitasking software requirements for multiple-instruction, multiple-data stream (MIMD) computer architectures. The focus was on specifying solutions for algorithms in the field of computational fluid dynamics (CFD). The program objectives were to allow researchers t o .produce useable parallel application software as soon as p...
