【摘要】： 随着中国的市场经济的深入发展,广告在经济中发挥的作用越来越重要。对于一个公司来说,无论是他的新开发的产品,还是老的成熟的产品,都需要通过广告来向消费者宣传。但是广告到底带来了多少效果,这需要广告公司根据收视数据来建立各种报表分析出来。对于中国这样大的市场来说,数据计算量是惊人的。 对于开发人员来说,面对超大的数据计算量,如何在企业级的硬件条件下在指定的时间内完成计算,是一个很大的挑战。传统的做法是:提高CPU主频,服务器增加CPU,增加内存,在一台服务器上面运行多进程,多线程的计算任务。但是单台服务器的资源毕竟有限,而在当今的今超级计算机,无一例外地采用并行运算技术以达到惊人的运算能力,而非依靠单一CPU实现强大运算的目的,分布式运算可谓是计算机产业发展的必然趋势。笔者在实际项目中尝试了把单任务分配到多服务器上的进行分布式并行计算。突破了单台机器的局限。 在本文,笔者结合了在实际项目中使用的基于WCF的分布式计算应用于电视收视率的计算方案。由简入繁,从总体设计到详细设计,逐步地分析了如何在基于WCF的基础上进行分布式并行计算。 文中首先对简单阐述了一下电视收视率计算原理,点出了电视收视率的几个要素,以及为什么就中国当前的市场规模,传统的单机计算方法不能满足巨大计算量的需求,需要采用分布式计算。然后就当前分布式计算的现状做了一个总体概述;然后对本文要重点分析的基于WCF服务的分布式计算的相关技术基础做了概括分析,包括:Windows服务技术概述、.NET Remoting技术概述、Web Service技术概述、以及WCF技术概述。其次对笔者利用文中讨论的技术方案的一个实际的项目做了一个背景介绍以及这个系统对分布式计算的具体需求。再次对基于WCF的分布式计算系统的总统设计,包括主要功能及特点、系统设计及基本拓扑结构。再后论述了基于WCF的分布式计算系统的详细设计:再后分析了其作为一个Service在被别的系统使用过程中的实际应用效果:最后总结了WCF的分布式计算系统技术方案,并在总结的基础上提出了该讨论的方案下一步可以继续研究分析的研究方向。
[Abstract]:With the development of China's market economy, advertising plays a more and more important role in the economy. For a company, both its newly developed products and older, mature products need to be advertised to consumers. But exactly how much advertising has brought, which requires agencies based on the viewing data to build various reports to analyze. For such a large market in China, the amount of data calculation is staggering. It is a great challenge for developers how to complete the computation in the specified time under the condition of enterprise hardware in the face of the huge amount of data computation. The traditional method is to improve the main frequency of CPU, the server to increase CPU, increase memory, running on a server multi-process, multi-thread computing tasks. However, the resources of a single server are limited after all, and in today's supercomputers, parallel computing techniques are used without exception to achieve amazing computing power, rather than relying on a single CPU to achieve powerful computing purposes. Distributed computing is an inevitable trend in the development of computer industry. In the actual project, the author tries to distribute the single task to multi-server for distributed parallel computing. Break through the limitation of single machine. In this paper, the author combines the distributed computing based on WCF used in the actual project to calculate the TV ratings. From simplicity to complexity, from overall design to detailed design, this paper analyzes how to carry out distributed parallel computing on the basis of WCF step by step. First of all, this paper briefly expounds the principle of TV ratings calculation, points out several elements of TV ratings, and why, in view of the current market scale in China, the traditional single-machine calculation method can not meet the demand of huge amount of calculation. Distributed computing is needed. Then it makes a general overview of the current situation of distributed computing, and then makes a general analysis of the related technical foundation of distributed computing based on WCF services, which is the focus of this paper. This paper includes: windows service technology overview,. Net Remoting technology overview, web Service technology overview, and WCF technology overview. Secondly, the author makes a background introduction to a practical project using the technical scheme discussed in this paper and the specific requirements of the system for distributed computing. Thirdly, the president design of the distributed computing system based on WCF, including the main functions and characteristics, the system design and the basic topology. After that, the detailed design of distributed computing system based on WCF is discussed. The practical application effect of distributed computing system as a Service in other systems is analyzed. Finally, the technical scheme of distributed computing system based on WCF is summarized. On the basis of the conclusion, the future research direction of this discussion is put forward.
