  • A parallel implementation of a fluid flow simulation using smoothed particle hydrodynamics

    Creator:
    Vertanen, Keith D.
    Abstract:
    The reaction of fluid or gas flowing around an obstacle is a common engineering problem. Computer simulations are often used to measure and visualize the physical processes involved. In this report, we will discuss a parallel implementation of a simulation using the Smooth Particle Hydrodynamics (SPH) approach to fluid flow....

  • A C* development environment for the Meiko CS-2 multicomputer

    Creator:
    Zhang, Chung
    Abstract:
    With sequential computing technology reaching its speed limits, parallel processing is emerg­ing as the key to very-high-speed computation. However, developing a parallel program is by no means a simple task; neither is analyzing the performance of parallel programs. C* is a high-level data-parallel language that hides explicit message passing and...

  • STYLE reference manual : an automated program style analyzer for Pascal programmers

    Creator:
    Lake, Al and Cook, Curtis R.
    Abstract:
    Programming style plays an important role in program understanding and maintenance. Studies [Par83] have shown that as much as one- half of a maintenance programmer's time is spent in activities related to understanding the program. Program understanding is also important for testing and debugging. Programming style embellishes the readability of...

  • Serializability test by pebbling

    Creator:
    Minoura, Toshimi
    Abstract:
    An execution of a database system is considered correct if its net effect is as if transactions were executed serially, and such an execution is called serializable. In this short paper we show that the serializability test problem can be reduced to a simple pebbling problem. Our characterization is intuitive...

  • Implementation of a prototype information resources management system using ACCELL 4GL and its comparison with an INFORMIX 4GL implementation

    Creator:
    Su, Dungywe
    Abstract:
    In this report, we describe an implementation of a prototype information resources management system for the synthesis and integration project of the forest response program using a 4GL application development system ACCELL. Our system is called Prototype Virtual Data Management System (PVDMS). ACCELL is a software package that combines a...

  • Critique : a prototype style critic for FORTRAN

    Creator:
    Luh, Shan
    Abstract:
    Programming style is important for program understanding in programming tasks such as maintenance. testing, and debugging. The goal of programming style is to improve the readability of the source program without adversely affecting its performance. Critique is a FORTRAN source program style critic which analyzes the source program and outputs...

  • The structural active-object system approach to AGV system editor implementation

    Creator:
    Yan, Jimmy and Minoura, Toshimi
    Abstract:
    The Structural Active-Object System (SAOS) approach allows rapid development of various concurrent systems by structural and hierarchical object composition (SHOC). We implemented, as a SAOS program, a graphical editing and simulation program for automatic guided vehicle (AGV) systems, which carry around parts in automated factories. It is difficult to predict...

  • Parallax : an implementation of ELGDF (Extended Large Grain Data Flow)

    Creator:
    Kim, Inkyu
    Abstract:
    The major obstacle to widespread parallel programming of multiprocessors is the lack of a convenient parallel programming system. PPSE (Parallel Programming Support Environment) is a unified approach to parallel programming. Parallax is developed as a component of PPSE based on ELGDF which is a graphical language for designing parallel programs....

    Liu, Xinying
    Abstract:
    Multimedia networking is one of the most exciting developments in today's Internet. Streaming technology; which allows the player to start playing audio/video data immediately instead of waiting for the entire file to be downloaded, presents an attractive vehicle for the distribution of multimedia content over the Internet. However, transmitting real-time...
