【摘要】： 隨著中國的市場經(jīng)濟的深入發(fā)展,廣告在經(jīng)濟中發(fā)揮的作用越來越重要。對于一個公司來說,無論是他的新開發(fā)的產(chǎn)品,還是老的成熟的產(chǎn)品,都需要通過廣告來向消費者宣傳。但是廣告到底帶來了多少效果,這需要廣告公司根據(jù)收視數(shù)據(jù)來建立各種報表分析出來。對于中國這樣大的市場來說,數(shù)據(jù)計算量是驚人的。 對于開發(fā)人員來說,面對超大的數(shù)據(jù)計算量,如何在企業(yè)級的硬件條件下在指定的時間內(nèi)完成計算,是一個很大的挑戰(zhàn)。傳統(tǒng)的做法是:提高CPU主頻,服務(wù)器增加CPU,增加內(nèi)存,在一臺服務(wù)器上面運行多進程,多線程的計算任務(wù)。但是單臺服務(wù)器的資源畢竟有限,而在當(dāng)今的今超級計算機,無一例外地采用并行運算技術(shù)以達到驚人的運算能力,而非依靠單一CPU實現(xiàn)強大運算的目的,分布式運算可謂是計算機產(chǎn)業(yè)發(fā)展的必然趨勢。筆者在實際項目中嘗試了把單任務(wù)分配到多服務(wù)器上的進行分布式并行計算。突破了單臺機器的局限。 在本文,筆者結(jié)合了在實際項目中使用的基于WCF的分布式計算應(yīng)用于電視收視率的計算方案。由簡入繁,從總體設(shè)計到詳細設(shè)計,逐步地分析了如何在基于WCF的基礎(chǔ)上進行分布式并行計算。 文中首先對簡單闡述了一下電視收視率計算原理,點出了電視收視率的幾個要素,以及為什么就中國當(dāng)前的市場規(guī)模,傳統(tǒng)的單機計算方法不能滿足巨大計算量的需求,需要采用分布式計算。然后就當(dāng)前分布式計算的現(xiàn)狀做了一個總體概述;然后對本文要重點分析的基于WCF服務(wù)的分布式計算的相關(guān)技術(shù)基礎(chǔ)做了概括分析,包括:Windows服務(wù)技術(shù)概述、.NET Remoting技術(shù)概述、Web Service技術(shù)概述、以及WCF技術(shù)概述。其次對筆者利用文中討論的技術(shù)方案的一個實際的項目做了一個背景介紹以及這個系統(tǒng)對分布式計算的具體需求。再次對基于WCF的分布式計算系統(tǒng)的總統(tǒng)設(shè)計,包括主要功能及特點、系統(tǒng)設(shè)計及基本拓?fù)浣Y(jié)構(gòu)。再后論述了基于WCF的分布式計算系統(tǒng)的詳細設(shè)計:再后分析了其作為一個Service在被別的系統(tǒng)使用過程中的實際應(yīng)用效果:最后總結(jié)了WCF的分布式計算系統(tǒng)技術(shù)方案,并在總結(jié)的基礎(chǔ)上提出了該討論的方案下一步可以繼續(xù)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.
