摘要

在过去的几十年里,人们对并行计算的认知价值出现了很大的波动。有时,并行计算被乐观地视为解决我们所有计算限制的方法。分析了传统验证方法的划分。最后得出结论:软件验证的综合方法是最相关、最有用和最有生产力的方法。本文指出,计算机系统软件的形式化验证方法的实施是对传统的测试和调试方法的补充,可以提高程序的正常运行时间和安全性。计算机系统软件形式验证方法可以保证系统模型对被验证属性的检验。如今,这些方法正朝着减少形式验证总成本、支持现代编程概念和最小化从系统模型到其实现过渡中的“手工”工作的方向积极发展。它们的主要特点是能够使用数学模型查找错误,而不依赖于现有的软件实现。这是非常方便和经济的。有几种特定的技术用于正式模型分析,如演绎分析,模型和一致性检查。每一种验证方法都是在特定情况下使用的,这取决于目标。软件验证的综合方法被认为是最实际、最有用和最有效的方法,因为它们以某种方式试图结合不同验证方法的优点,从而消除它们的缺点。目前,这些方法的开发及其在工业软件开发实践中的实现已经取得了重大进展。

Analysis of existing parallel programs verification technologies
The past few decades have seen large fluctuations in the perceived value of parallel computing. At times, parallel computation has optimistically been viewed as the solution to all of our computational limitations. The conventional division of verification methods is analyzed. It is concluded that synthetic methods of software verification can be considered as the most relevant, most useful and productive ones. It is noted that the implementation of the methods of formal verification of software of computer systems, which supplement the traditional methods of testing and debugging, and make it possible to improve the uptime and security of programs, is relevant. Methods of computer systems software formal verification can guarantee the check that verified properties are performed by system model. Nowadays, these methods are actively being developed in the direction of reducing the formal verification total cost, support of modern programming concepts and minimization of "manual" work in the transition from the system model to its implementation. Their main feature is an ability to search for errors using mathematical model, without recourse to existing realization of software. It is very convenient and economical. There are several specific techniques used for formal models analysis, such as deductive analysis, model and consistence check. Every verification method is been used in particular cases, depending on the goal. Synthetic methods of software verification are considered the most actual, useful and efficient, as they somehow try to combine the advantages of different verification approaches, getting rid of their drawbacks. Currently, there has been made significant progress in the development of such methods and their implementation in the practice of industrial software development.
