  • Parallel simplex algorithms and loop spreading

    Creator:
    Wu, Youfeng
    Abstract:
    Parallel solutions for two classes of linear programs are presented. First we parallelized the two-phase revised simplex algorithm and showed that it is possible to get linear improvement in performance. The simplex algorithm is the best known algorithm for solving linear programs, and we claim our result is the best...

  • A multiprocessor node for communication and control

    Creator:
    Atluri, Venkata Ram
    Abstract:
    This paper describes the design and implementation of "A multiprocessor node for communication and control" (MPCC). MPCC is a high speed, high performance local area network capable of performing real time control tasks. This is achieved by the concurrent operation of two 8051 microcontrollers, a dual port RAM and the...

  • Concurrent message transmission on short delay ring networks

    Creator:
    Xu, Mingcheng
    Abstract:
    Two new medium access protocols for ring type local area networks, CTR (Concurrent Token Ring) protocol and DRUID (Destination Removal withoUt Intermediate node Delay) ring protocol, are proposed, designed and analyzed. A destination partial removal technique is designed and used in these two protocols to support concurrent message transmission and...

  • A programmable system scheduler for control oriented local area networks (COLAN)

    Creator:
    Lim, Choo-chiang
    Abstract:
    The Control-Oriented Local Area Network (COLAN) is a distributed control system for a series of networked microcontrollers, which has been under development at Oregon State University since 1986. A reliable master controller, functioning both as a task scheduler and as a network controller, is required to allow users to perform...

  • Task partitioning and scheduling on arbitrary parallel processing systems

    Creator:
    El-Rewini, Hesham
    Abstract:
    Parallel programming is the major stumbling block preventing the parallel processing industry from quickly satisfying the demand for parallel computer software. This research is aimed at solving some of the problems of software development for parallel computers. ELGDF is a graphical language for designing parallel programs. The goal of ELGDF...

  • Scheduling system of affine recurrence equations by means of piecewise affine timing functions

    Creator:
    Mui, Lap K.
    Abstract:
    Many systematic methods exist for mapping algorithms to processor arrays. The algorithm is usually specified as a set of recurrence equations, and the processor arrays are synthesized by finding timing and allocation functions which transform index points in the recurrences into points in a space-time domain. The problem of scheduling...

  • Data-structure builder for VLSI/CAD software

    Creator:
    Eum, Doo-hun
    Abstract:
    Relational database systems have successfully solved many business data processing problems. The primary reason of this success is that the relational data model provides a simple, yet flexible view of data as tables. In studying VLSI/CAD data, we noticed that they are often represented in formats similar to relational tuples....

  • AOPS : an abstraction oriented programming system for literate programming

    Creator:
    Shum, Stephen M.
    Abstract:
    The practice of literate programming is not widespread because existing literate programming systems have some undesirable characteristics such as programming language and text processor dependence and lack of flexible tools for viewing and manipulation of the source file. This dissertation describes the literate programming system AOPS (Abstraction Oriented Programming System)...

  • Active object systems

    Creator:
    Choi, Sungwoon
    Abstract:
    An active object system is a transition-based object-oriented system suitable for the design of various concurrent systems. An AOS consists of a collection of interacting objects, where the behavior of each object is determined by the transition statements provided in the class of that object. A transition statement is a...

  • Cluster partitioning approaches to parallel Monte Carlo simulation on multiprocessors

    Creator:
    Ranawake, Udaya A.
    Abstract:
    We consider the parallelization of Monte Carlo algorithms for analyzing numerical models of charge transport used in semiconductor device physics. Parallel algorithms for the standard k-space Monte Carlo simulation of a three band model of bulk GaAs on hypercube multicomputers are first presented. This Monte Carlo model includes scattering due...
