  • An attributed-based database structure for small computers

    Creator:
    Elton, Terry J.
    Abstract:
    Contemporary database systems are used in a variety of business applications requiring rapid retrieval of on­line data. When records contain unique information indexed by a single key, the retrieval operation can be simplified. However, when added generality and flexibil­ity is needed, inverted files and sophisticated data models result in a...

  • Probability of deadlock in a system of processes and resources for shared and exclusive access

    Creator:
    Baghgandomi, Shahla Saidi
    Abstract:
    A process-resource graph is a directed graph with m resource nodes and n process nodes. A request edge is directed from a process to a resource. An assignment edge is directed from a resource to a process. A cycle in the process-resource graph is a necessary and sufficient condition for...

  • Duality and the bounded-buffer problem

    Creator:
    James, Mark Allen
    Abstract:
    The paper, "On the Duality of Operating System Structures," by Lauer and Needham [21], claims that operating systems can be modeled as procedure-oriented or message-oriented, and that the two models are duals of each other. Duality, in this case, means that the models are logically and functionally equivalent, and have...

  • An interpreter for a very-high level language (BAGIT)

    Creator:
    Chou, Kuo-Wei
    Abstract:
    The purpose of this project is to design and imple­ment an intermediate language interpreter for a very high level language called Bagit. The Bagit compiler produces Bcode, and this in turn is interpreted by the program described in this report.

  • Design and implementation of a modelling language user interface

    Creator:
    Strickler, Braden
    Abstract:
    A user interface for a modelling language called HELM was designed and implemented on the Macintosh. HELM is a modelling language for specifying a linear programming model. The user interface is called Model Maker and it is part of the whole user interface; it contains a graphical editor for specifying...

  • 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 benchmark suite for parallel processors : part I

    Creator:
    Sun, Tieh-Jun
    Abstract:
    Advanced computer architectures are centered around the parallel computer systems. This project is focused on the experiment on two parallel computer architectures : Sequent Balance 21000 shared memory multiprocessor and Cogent XTM distributed system. A set of benchmark programs are implemented using "C" language and Dynix parallel programming library on...

  • HELM, hierarchical environment for linear modeling

    Creator:
    Brown, Carol E.
    Abstract:
    Several problems relating to linear programming modeling have been identified: (1) model formulation, validation and explanation are difficult and time consuming; (2) models must be frequently updated and debugged; (3) flexibility is needed to specify the model schema for a class of problems as a group; and (4) significant differences...

  • MacSchedule : speedup estimation in parallel program task graphs

    Creator:
    Fortner, Patrick D.
    Abstract:
    Parallel computers have generated a great deal of excitement and interest in the computer industry as well as the computer user industries. Parallel computers offer the promise of enormous gains in computing speeds by allowing multiple processors to work on different pieces of the same problem at the same time....

    Abstract:
    This research paper is limited to the User Interface of the modeling language of HELM (Hierarchical Environment for Linear Modeling). In attempt to better describe the user interface for HELM, some examples and portions of Carol Brown's report are included for ease of reading and a brief overview of the...
