The purpose of this project is to study the benefit at large parking lots having shuttle busses by providing a system that dynamically routes a shuttle. The shuttle route will be set by the placement of the travelers returning from the terminal. A parking space is assigned to the incoming...
The processor allocation in an n-dimensional hypercube multiprocessor using buddy strategy, gray code strategy, and a new strategy is implemented on Macintosh. Our implementations show that when processor relinquishment is not considered (i.e. static allocation), all these strategies are optimal in the sense that each incoming request sequence is always...
The majority of database users interact with database systems by manipulating forms. This paper discusses the fundamental mechanisms underlying forms and considers how these mechanisms affect the behavior of forms. We then review the forms supported by commercial products. None of the packages reviewed provide all of the features that...
A good code generator must effectively utilize the registers provided by the target architecture. Although a number of register allocation techniques exist, few address the issues involved in multiple register banks and no known techniques exist for effectively using register banks of the same type that are associated with multiple...
A new technique of implementing the object-oriented language Little Smalltalk is developed using tuple space communication of Linda. In this implementation, the language's abstract constructs such as object, class, and method are naturally mapped into tuple space. Since Linda's tuple space is designed to facilitate parallel processing, this implementation technique...
The Dataset Revision Control System (DRCS) is a data management tool for managing the changes made to scientific datasets. Using a new model of revisions, it stores the changes or revisions as reverse deltas. The DRCS model of revisions includes two kinds of update operations besides insert and delete operations....
The Server System/1 (SS/1) Design Editor is a graphical programming tool that provides a simple interface for object oriented parallel programming. Two difficult problems with parallel programming, partitioning, end visualization are addressed by the SS/1 Design Editor. An SS/1 program is structured using object oriented design concepts. This leads to...
Task Grapher is a tool for the study of optimal parallel program task scheduling on arbitrary interconnected parallel processors. Given a task graph, this tool can be used to produce several kinds of displays to help users to determine optimal scheduling heuristics and optimal machine topology.
Previous versions of Task...
Oregon SpeedCode Universe (OSU) is a rapid prototyping system which automates the production of applications from a description of the user interface. GraphLab is a domain-specific tool which deals with several major problems concerning OSU: (1) limited functionality, that is, lacking graphical capabilities in generated applications, (2) indirect approach to...
