Applications of nonlinear equations in several computing problems 非线性方程组在几类计算问题中的应用
The computed problem was the same as the experimental problem of cheng xu and k eaton in 1997 计算对象与1997年chengxuandkeaton研究的实验模型相同。
Defects of some classical methods appear in pratice . and they become more distinct in large scale computing problem . we try to seek deformations of classical methods 一些经典的方法经过严格的实践检验,显露出了若干缺陷,而这些缺陷在计算量非常大的实际问题中碰到的非线性方程的求解时,显得尤为突出
As applications grow in size, together with the development of computing technology, parallel computing gets more and more necessary and has become the only way to solve many large-scale scientific computing problems 随着应用的深入和计算技术的发展,并行计算在数值计算领域里扮演着越来越为重要的角色,成为了解决很多大规模科学计算问题的唯一途径。
Rather than needing to understand the intricacies of the data and compute problems in detail, we have found that making a single high-level decision and directing the underlying technologies to act in a given way provides much of the functionality we need 我们并不需要详细了解数据和计算问题的错综复杂之处,而是找到制定单个高级决策并引导底层技术按照给定的方式提供我们所需要的功能。
Corba is the best way to solve distributed computing problems . as the corba is rapidly developed and the corba object can not be managed in our country yet, this paper refers to the theory of the corba technology, it also designs and builds the concept model of the management system . the dynamical management of the corba objects is accomplished according to this model, and it solves some problems of controlling 本文主要针对我国目前corba技术迅猛发展而对corba对象的管理仍是空白的现状介绍了corba技术的有关原理、设计并建立了corba对象管理的系统概念模型,在此模型基础上实现了动态地对corba对象的有效管理,解决了一些corba对象的监视和控制方面的难题。
Our objectives are to ( 1 ) clarify the nature of vos and grid computing for those unfamiliar with the area; ( 2 ) contribute to the emergence of grid computing as a discipline by establishing a standard vocabulary and defining an overall architectural framework; and ( 3 ) define clearly how grid technologies relate to other technologies, explaining both why emerging technologies do not yet solve the grid computing problem and how these technologies can benefit from grid technologies 作者的目标有三个:一是给非该领域的人介绍vo和网格的概念,二是为发展中的网格技术引入标准的专用术语和体系结构,三是介绍网格和其它技术的关系,解释为何其现在还没有解决网格计算的问题介绍这些技术将如何从网格技术中受益。
Npupar can guarantee the correctness of iteratively field computing problems . but due to the existence of mass complex structure in sequential program and the diversity of the programming style, conservative analysis is generally adopted in npupar, which leads to low parallel efficiency 它对于迭代求解的场计算问题能够保证正确性,但由于串行程序中大量复杂结构的存在,以及程序员书写程序的不规范性,该系统多采用保守的分析方法,结果生成大量的冗余通信,导致并行效率低下。
With these backgrounds, the object being investigated in this article is composite metallic and dielectric structure which is composed by piecewise homogeneous, linear and isotropic medium, the problem being investigated is the complex scattering and radiation problem, the intention being investigated is modeling and fast computing the electromagnetic characteristic of electric large complex structures with uniform method, the final objective is developing general fast electromagnetic computing software to solve the realize electromagnetic computing problems in engineering 本文就是围绕这一背景展开的,研究对象是由分块连续、线性、各向同性媒质组成的“金属与介质混合结构”,研究问题是复杂的散射和辐射问题,研究目标是以统一的方法对电大尺寸复杂结构作电磁建模与快速计算,最终目的是开发通用的电磁计算程序,来解决一些工程中的复杂电磁计算问题。
The thesis mainly resolved the database security issue, the ldap ’ s accessing mechanism and the problem of how jndi ( java naming and directory interface ) connects to the ldap server, etc . the thesis tested the performance of the computing pool with the power system flow parallel computing problem, and compared the performance of the computing with and without the computing pool management 论文在设计过程中主要解决了涉及到的数据库安全性问题、ldap的访问机制问题以及jndi(javanaminganddirectoryinterface)如何连接ldap服务器的问题等。论文在计算池中运行电力系统潮流并行计算来测试计算池的性能,并与未经过计算池管理的潮流并行计算进行了比较。
