Issues on performance and yield in defect- and fault-tolerant multiprocessors are being addressed in this research. Two different classes of multiprocessors are being considered in the research: shared-memory multiprocessors and multicomputer systems with local memory. Issues relating to metrics for capturing the most important properties of multiprocessors and algorithms for calculating the yield and performance of multiprocessors are being studied. The benefits and drawbacks of increasing the level of integration in the design of multiprocessors are being investigated. This research will result in an ability to determine the best level of integration for a given defect- and fault-tolerant multiprocessors system. Improvements in technology have reduced the defect density as well as the failure rates of all components in multiprocessing systems. However, the large increase in the number of components per system has more than offset the increase in yield and reliability of a single component. It is desirable that a given system have graceful degradation in performance in the presence of faulty components. The proposed research addresses the important issues of estimating performance and yield of multiprocessors and the benefits and drawbacks of increased level of integration. Results obtained will allow the design of more reliable and fault-tolerant multiprocessors. Support is strongly recommended.

这项研究正在解决有关缺陷和容忍缺陷多处理器的性能和产量的问题。 研究中正在考虑两种不同类别的多处理器：具有本地内存的共享内存多处理器和多机构系统。 与指标相关的问题，用于捕获多处理器的最重要属性和计算多处理器的产量和性能的算法。 正在研究提高多处理器设计集成水平的好处和缺点。 这项研究将使能够确定给定缺陷和容忍缺陷的多处理器系统的最佳集成水平。 技术的改进已降低了多处理系统中所有组件的缺陷密度和故障率。 但是，每个系统的组件数量的大幅增加远远超过了单个组件的产量和可靠性的提高。 在存在故障组件的情况下，给定的系统在性能方面具有优美的降解。 拟议的研究探讨了估计多处理器的绩效和产量的重要问题，以及整合水平提高的益处和缺点。 获得的结果将允许设计更可靠和耐断层的多处理器。 强烈建议支持。
