【摘要】 近年来分布式计算受到了特别关注，它给人们展示一种环境，在该环境中能方便地利用网络系统上众多计算机的闲置资源，让它们协同工作，执行以往只能由超级计算机完成的计算密集型任务。在目前和可预期的将来分布式计算都将是一个活跃的领域，有很大的发展前景。 本文旨在给用户提供一个概念简单、使用方便、与具体计算任务无关的分布式计算方案。使用该平台，计算任务自动移动到别的计算机上完成并返回需要的结果。首先文章在分析各层次、多种软件技术的情况下，提出了该平台一种简洁的完整解决方案。接着在研究面向对象的基本概念和统一建模语言(UML)的基础上，应用面向对象思想，采用UML软件建模工具对分布式计算平台进行了分析和建模，给出了多种UML图和详细文档。在随后的设计过程中，本文运用一些在实践中被证明行之有效的软件设计模式，使得设计清晰易懂，大大缩短了程序开发周期。让系统具有较高的可复用度和灵活性，便于扩展。 在对系统编码实现并测试后，详细介绍了本平台的使用方法；利用本平台提供的资源，开发了实验性的客户应用程序作为示例，并给出了实验结果和结论。实践结果表明本系统达到了预期的要求、取得了良好的效果。更多还原

【Abstract】 One flavor of distributed computing has received a lot of attention lately, and it will be a primary focus of this situation--an environment where you can harness conveniently idle resourses of hundreds, or thousands of networked systems to work together on a particularly processing-intensive problem which only can be accomplished by super computer before. At present and in the predictable future distributed computing will be an active and promising domain.The purpose of this paper is giving a distributed computing scheme which is simple in concept and can be used expediently. And exspecially it is a scheme which has no relations with the concrete task.Based on the study of traditional distributed processing technology and other software technology the paper brought forward a concise solution to build the platform. After the basic theories of OOP(Object Oriented Programming) and UML(Unified Modeling Language) are introduced, by using Object Oriented method the distributed computing platform is analyzed and designed using UML as a tool, several kinds of diagram and detailed documentation are given. This paper adopts some design pattern that has been proved to be efficacious in practice process, which makes design clear and design time shorter. Owing to those technologies the system get good reusability and agility simultaneously and it is convenient to be extended.After the system was coded and tested, the usage of the platform was introduced in detail. Finally as examples two experimental program was developed, the result and conclusion was given. According to the practice and it’s result the distributed computing platform satisfies the anticipant request and has good effectivity.更多还原
