多台PC实现分布式服务器的应用和分析

在一些特殊应用中，常会出于成本的考虑，使用多台PC作为服务器，由于PC自身性能有限，因此，在应用中会遇到一些问题，比如PC的稳定性较差，不宜扩展，主板时钟不够准确等。本文讨论了解决这些问题的方法，并利用Petri网对其性能进行了分析。

Application and Analysis of the Distributed Server Realized by Multiple PCs

In some special applications, several PCs are used as a server for economical reasons. Because the performance of a certain PC is limited, such as the imperfection of stability, the lack of expansibility and the inaccurateness of the clock on the main board, there are some problems in practice. This article discusses the method that can settle these problems, and analyses its performance by means of Petri nets.
