Research in Reliable Distributed Computing Systems

分布式计算中的可靠性和崩溃恢复机制 系统正在研究，特别是在分布式数据库中 系统. 正在开发工具，以评估和比较 解决方案;并使用这些和其他工具，解决几个 具体问题分门别类， 研究 强调算法实现和实验性能 新的实验网络上的测量，包括五个 磁盘容量超过1G的计算机。 目标是 研究可靠运行的新算法，因此系统 用于推动研究。 也就是说， 实施和评估，以了解其优势 和实际限制。 这反过来又表明了变化， 算法的改进将引领新的方向。 甚至 虽然工作重点是系统的实施，但他们继续 适当时使用模拟和分析。

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.
