Abstract

Distributed programs are much more difficult to design, understand and implement than sequential or parallel ones. This is mainly due to the uncertainty created by the asynchrony inherent to distributed machines. So appropriate concepts and tools have to be devised to help the programmer of distributed applications in his task. This paper is motivated by the practical problem called distributed debugging. It presents concepts and tools that help the programmer to analyze distributed executions. Two basic problems are addressed: replay of a distributed execution (how to reproduce an equivalent execution despite of asynchrony) and the detection of a stable or unstable property of a distributed execution. Concepts and tools presented are fundamental when designing an environment for distributed program development. This paper is essentially a survey presenting a state of the art in replay mechanisms and detection of unstable properties on global states of distributed executions.<>
介绍分布式计算的分析与调试
与顺序或并行程序相比,分布式程序的设计、理解和实现要困难得多。这主要是由于分布式机器固有的异步所造成的不确定性。因此,必须设计适当的概念和工具来帮助分布式应用程序的程序员完成他的任务。本文的灵感来自于分布式调试的实际问题。它提供了帮助程序员分析分布式执行的概念和工具。解决了两个基本问题:分布式执行的重播(如何在异步的情况下重现等效的执行)和分布式执行的稳定或不稳定属性的检测。所提出的概念和工具是设计分布式程序开发环境的基础。本文本质上是对分布式执行全局状态下的重放机制和不稳定属性检测的最新研究。
