Multicomputers and multiprocessors, first introduced in the mid 1980s, employ large numbers of microprocessors working in parallel to achieve high performance at low cost. These parallel machines represent an exciting new generation in supercomputing, but their usefulness is currently limited by inadequate programming languages and environments. This problem is being...
There are lots of mailing systems available for Apple Macintosh computers. But when this research was started, there were no Voice Mail System for the Macintosh. However, a similar system was available for the NeXT machine. So the main goal of this research was to develop a Voice Mail System...
The information processing industry is one of the fastest growing, and most dynamic industries on the scientific as well as business scene, today. Progress in designing and applying computing systems has out raced progress in evaluating their performance. In order to circumvent this trend, there should be a simultaneous development...
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...
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...
This is an attempt to deal with interface problems of interacting modules in a large simulation system.
In simulation, scientists require routine substitution of modules for comparison of alternative models. These changes have propagating side affects and from a programmer's point of view are essentially system redesigns.
This paper presents...
The task of designing and building the user interface portion of a Macintosh application is radically different than the same task on a more conventional computer with a conventional operating system. Just the fact that it is radically different makes it very time consuming to learn how to program this...
