    Explains set theoretic estimation, which is governed by the notion of feasibility and produces solutions whose sole property is to be consistent with all information arising from the observed data and a priori knowledge. Each piece of information is associated with a set in the solution space, and the intersection of these sets, the feasibility set, represents the acceptable solutions. The practic...

  • Comments, with reply, on 'Synchronization and relativity' by G.M.R. Winkler

    The commenter asserts that the above-titled paper by G.M.R. Winkler (see ibid., vol.79, no.7, p.1029-39, July 1991) perpetuates a fairly widespread fundamental error by using a semipopular explanation for the dissemination of time in rotating frames of reference. The misconception that one must employ general relativity to describe kinematic phenomena (synchronization, Sagnac effect, etc.) in acce... View full abstract»

  • Multithreaded languages for scientific and technical computing

    Publication Year: 1993, Page(s):288 - 304

    An overview of language support for parallel technical computing is provided. The rationale for multithreaded languages, in which the programmer explicitly specifies what work is to be carried out by multiple processors and how their activities should be coordinated, is described. The discussion begins with an introduction to the general models for manipulating multiple threads and how they are in... View full abstract»

    The quality technologies developed by Bell Communications Research (Bellcore) and adopted by its owner/clients are described. At the core of the philosophy is the concept of supplier accountability for product and service quality. A brief history of quality in the former Bell System is presented. A supplier career path for today's telecommunications suppliers is shown, and the various characterist... View full abstract»

    An overview of automatic program parallelization techniques is presented. It covers dependence analysis techniques, followed by a discussion of program transformations, including straight-line code parallelization, do-loop transformations, and parallelization of recursive routines. Several experimental studies on the effectiveness of parallelizing compilers are surveyed View full abstract»

    The ParaScope parallel programming environment, developed to support scientific programming of shared-memory multiprocessors, is described. It includes a collection of tools that use global program analysis to help users develop and debug parallel programs. The focus is on ParaScope's compilation system. The compilation system extends the traditional single-procedure compiler by providing a mechan... View full abstract»

    Compilation techniques for the source-to-source translation of programs in an extended FORTRAN 77 to equivalent parallel message-passing programs are discussed. A machine-independent language extension to FORTRAN 77, Data Parallel FORTRAN (DPF), is introduced. It allows the user to write programs for distributed-memory multiprocessing systems (DMMPS) using global addresses, and to specify the dist... View full abstract»
