Research in Reliable Distributed Computing Systems

人们正在研究分布式计算系统，特别是分布式数据库系统的可靠性和崩溃恢复机制。正在开发评估和比较解决办法的工具；使用这些工具和其他工具，对几个特定问题的解决方案进行分类和分类。研究重点是在新的实验网络上实现算法和实验性能测量，该网络由五台计算机组成，磁盘存储超过1gb。目标是研究可靠运行的新算法，因此所实施的系统用于推动研究。也就是说，新算法的实现和评估是为了了解它们的优势和实际局限性。这反过来又提出了算法的变化和改进，这些算法将引领新的方向。即使工作集中在系统实现上，他们也会在适当的时候继续使用模拟和分析。

Mechanisms for reliability and crash recovery in distributed computing systems are being studied, particularly in distributed database systems. Tools are being developed for evaluating and comparing the solutions; and using these and other tools, solutions for several specific problems are classified and categorized. The research emphasizes algorithm implementation and experimental performance measurement on the new experimental network consisting of five computers with over one gigabyte of disk storage. The goal is to investigate novel algorithms for reliable operation, so the systems implemented are used to drive the research. That is, new algorithms are implemented and evaluated in order to understand their strengths and practical limitations. This, in turn, suggests variations and improvements on the algorithms that will lead in new directions. Even though the efforts center on system implementation, they continue to use simulation and analysis when appropriate.
