    A tutorial on dependability and performance-related dependability models for multiprocessors is presented. Multiprocessors are classified as having shared-memory or distributed-memory architectures, and some fundamental dependability modeling concepts. Reliability models based on four types of reliability evaluation techniques (terminal, multiterminal, task-based, and network reliability) are exam... View full abstract»

    A system architecture called the recovery metaprogram (RMP) is proposed. It separates the application from the recovery software, giving programmers a single environment that lets them use the most appropriate fault-tolerance scheme. To simplify the presentation of the RMP approach, it is assumed that the fault model is limited to faults originating in the application software, and that the hardwa... View full abstract»

    Existing fault-tolerant clock synchronization algorithms are compared and contrasted. These include the following: software synchronization algorithms, such as convergence-averaging, convergence-nonaveraging, and consistency algorithms, as well as probabilistic synchronization; hardware synchronization algorithms; and hybrid synchronization. The worst-case clock skews guaranteed by representative ... View full abstract»

  • Built-in self-testing of random-access memories

    Publication Year: 1990, Page(s):45 - 56

    Built-in self-test (BIST) methods are examined, including the fault models and the test algorithms on which the BIST implementations are based. The notion of generic test architectures suitable for implementing a wide variety of test algorithms is introduced. A taxonomy for test architectures is provided and used to categorize BIST implementations, and important implementations are surveyed. It is... View full abstract»

    A set of situations that are susceptible to network disasters is identified. Several examples of actual breakdowns are presented. Although they occurred in different types of networks, they have grant similarities. Several examples of potential breakdowns that can result from very subtle design failures are also given. The discussion supports the belief that distributed programs in general can hav... View full abstract»

    Significant findings from the 1988-9 Taulbee report, which is based on a December 1989 survey of the Forsythe list of computing departments, are summarized. The survey focuses on the production and employment of PhDs who graduated in 1988-89 and the faculty of PhD-granting computing departments during the 1989-90 academic year. Among the findings is an 8% increase in PhDs granted. Of the 625 new P... View full abstract»
