Performance Enhancement of XML Parsing Using Regression and Parallelism

The Extensible Markup Language(XML)files,widely used for storing and exchanging information on the web require efficient parsing mechanisms to improve the performance of the applications.With the existing Document Object Model(DOM)based parsing,the performance degrades due to sequential processing and large memory requirements,thereby requiring an efficient XML parser to mitigate these issues.In this paper,we propose a Parallel XML Tree Generator(PXTG)algorithm for accelerating the parsing of XML files and a Regression-based XML Parsing Framework(RXPF)that analyzes and predicts performance through profiling,regression,and code generation for efficient parsing.The PXTG algorithm is based on dividing the XML file into n parts and producing n trees in parallel.The profiling phase of the RXPF framework produces a dataset by measuring the performance of various parsing models including StAX,SAX,DOM,JDOM,and PXTG on different cores by using multiple file sizes.The regression phase produces the prediction model,based on which the final code for efficient parsing of XML files is produced through the code generation phase.The RXPF framework has shown a significant improvement in performance varying from 9.54%to 32.34%over other existing models used for parsing XML files.

A Study of Parallelism in English Speeches

Every public speaker prepares his or her public speech meticulously.Witty remarks emerge in an endless stream,and demonstrate the rhetoric beauty of English to a great extent.Almost every speaker employs parallelism in his or her public speeches.The present paper is intended to study the concept,the classification and the significance of parallelism in English.

从功能和认知的视角看Parallelism

从功能解释语言现象是人类认知和交际的普通模式。普通模式的建立是作为对语言进行功能解释的前提 ,也是人类认知世界和传递信息的哲学抽象。我们可以从功能和认知的视角 。

论Parallelism的形式及功能

本文从形式及功能两个方面对英语ｐａｒａｌｌｅｌｉｓｍ进行了较为深入的探讨，并将其定义为：将同一词语并列重复，或将结构相同或相似、语义相关（相同、相似、互补或相反）、语气一致的词、词组、分句、句子或段落并列使用的一种修辞手段，同时指出，Ｐａｒａｌｌｅｌｉｓｍ不仅具有突出语义、增强韵律的功能，而且具有很强的语篇功能。

英语Parallelism修辞格

英语Parallelism译成汉语时分别为“对偶”、“排比”或“排偶” ,因为它在文中起的修辞作用不同 ,有时它相当于对偶的修辞方法 ,有时它又相当排比修辞方法。它的格式除在句法结构上相对外 ,有时也在音律、韵律、语法。

功能对等理论指导下Parallelism的翻译——以The Road Less Traveled为例

Parallelism在英语中具有修辞和语法双重功能。在英汉翻译对比研究中,学术界关注较多的是它与中文排比的构成差异及修辞功用,对它的语法功能研究较少。实践证明,英汉排比结构的对等转译不仅有助于保留源文本的语言特色和功能,还可以帮助译文读者更好地把握原文结构,明了行文思路。Parallelism的修辞功能和语法功能同等重要,都应引起译界的足够重视。本文在功能对等理论的指导下,以美国作家M·斯科特·派克的心理学著作——The Road Less Traveled中的排比句的翻译为例,探讨如何通过直译法、转译法、分句法、逆序法、增词法和减词法来提高原文读者和译文读者反应的相似性,实现功能对等目的。

Parallelism之分类、特征、功能及应用

一般来说,写文章都离不开修辞(Figure ofspeech),Parallelism(平行结构,又称排比结构)是英语修辞上的一种写作技巧,即用类似的语法形式来表达类似的概念。具体地说,平行结构要求:当—个句子的某些部分并列使用或由关联词连接时,句子的这些部分必保持相同的语法结构。

Frequency-domain elastic full-waveform multiscale inversion method based on dual-level parallelism

The complexity of an elastic wavefield increases the nonlinearity of inversion, To some extent, multiscale inversion decreases the nonlinearity of inversion and prevents it from falling into local extremes. A multiscale strategy based on the simultaneous use of frequency groups and layer stripping method based on damped wave field improves the stability of inversion. A dual-level parallel algorithm is then used to decrease the computational cost and improve practicability. The seismic wave modeling of a single frequency and inversion in a frequency group are computed in parallel by multiple nodes based on multifrontal massively parallel sparse direct solver and MPI. Numerical tests using an overthrust model show that the proposed inversion algorithm can effectively improve the stability and accuracy of inversion by selecting the appropriate inversion frequency and damping factor in low- frequency seismic data.

In this paper, the first boundary problem of quasilinear parabolic system of second order is studied by the finite difference method with intrinsic parallelism. for the problem, the stability of the difference schemes with intrinsic parallelism are justified in the sense of the continuous dependence of the discrete vector solution of the difference schemes on the discrete data of the original problem, without assuming the existence of the smooth solutions for the origillal problem.

Towards efficient deep neural network training by FPGA-based batch-level parallelism

Training deep neural networks(DNNs)requires a significant amount of time and resources to obtain acceptable results,which severely limits its deployment in resource-limited platforms.This paper proposes DarkFPGA,a novel customizable framework to efficiently accelerate the entire DNN training on a single FPGA platform.First,we explore batch-level parallelism to enable efficient FPGA-based DNN training.Second,we devise a novel hardware architecture optimised by a batch-oriented data pattern and tiling techniques to effectively exploit parallelism.Moreover,an analytical model is developed to determine the optimal design parameters for the DarkFPGA accelerator with respect to a specific network specification and FPGA resource constraints.Our results show that the accelerator is able to perform about 10 times faster than CPU training and about a third of the energy consumption than GPU training using 8-bit integers for training VGG-like networks on the CIFAR dataset for the Maxeler MAX5 platform.
