In architectures of parallel computing system, which has a large number of processing nodes, communication overhead is an important metric to evaluate and minimize by improving computation speedup solutions. In this paper, we propose using Stochastic Colored Petri Net to give models of parallel computing multi-processing systems for analyzing and evaluating effectiveness of communication overhe...

In addition, data-parallel algorithm introduced convolutional neural...

Adaptive techniques can be applied to improve performance of a beamformer in a cluttered environment. The sequential implementation of an adaptive beamformer, for many sensors and over a wide band of frequencies, presents a serious computational challenge. By coupling each transducer node with a microprocessor, in-situ parallel processing applied to an adaptive beamformer on a distributed syste...

Image processing is a task of analysing the image and produces a resultant output in linear way. Image processing tasks are widely used in many applications domains, including medical imaging, industrial manufacturing, entertainment and security systems. Often the size of the image is very large, the processing time has to be very small and usually real-time constraints have to be met. The imag...

This paper ~ descr ibes the construction of syntactic structures within an incremental multi-level and parallel generation system. Incremental and parallel generation imposes special requirements upon syntactic description and processing. A head-driven grammar represented in a unification-based formalism is introduced which satisfies these demands. Furthermore the basic mechanisms for the paral...

The research activities are divided into three stages, with each stage lasting approximately one month. In the first stage ', we discussed the design trade-off for real-time SAR processing. The objectives are to maximize the processing density (MFLOPS/volume, MFLOPVweight, MFLOPS/watt), to minimize the hardware cost (MFLOPS/dollar), to minimize the software development cost, and to maximize sof...

This paper presents an implementation method and experimental results of an extensible parallel processing system for databases. We have already proposed a stream-oriented parallel processing scheme (stream-oriented ncheme) of basic operations for databases and knowledge bases. This scheme is based on the demand-driven evaluation incorporating stream processing. We have designed basic primitive...

In this thesis, I designed, implemented, and analyzed the performance of an optimized storage manager for the Wavescope project. In doing this, I implemented an importation system that converts CENSAM data into a format specific to the processing system and cleans that data from measurement errors and irregularities; designed and implemented a highly efficient bulk-data processing system that i...
