    Known results regarding consensus among processors are surveyed and related to practice. The ideas embodied in the various proofs are explained. The goal is to give practitioners some sense of the system hardware and software guarantees that are required to achieve a given level of reliability and performance. The survey focuses on two categories of failures: fail-stop failures, which occur when p... View full abstract»

    Various schemes proposed for storing more information in the bar code label are reviewed. The concept of information density is introduced. The constraints imposed by the reading technology are addressed, and various recently proposed stacked bar codes are surveyed. Certain non-bar-code solutions are discussed.<> View full abstract»

    The tool abstraction paradigm, which supports the evolution of large-scale software systems by easing design changes in the system functions, is discussed. Systems that support tool abstraction are structured as a pool of abstract data structures shared by a collection of cooperating 'toolies', where each toolie provides a piece of the overall system function. When one toolie updates the shared da... View full abstract»

    A methodology that allows users to efficiently bridge the gap between high-level language and low-level microcode when implementing intensive mathematical operations and manipulations algorithms is discussed. The use of an optimized special-purpose array processor (SPAP) architecture for numerical computation and a host microprocessor for nonnumerical computation operations is described. The advan...

    An overview of the main techniques for designing fault-tolerant software and hardware systems is provided. The important features of the building blocks (computers, memories, buses, etc.) that can support an efficient implementation of fault-tolerant open distributed systems (FTODSs) are identified. Taking into account the features of these building blocks, an organization for FTODS is proposed. A... View full abstract»
