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....
A problem with a number of available parallel programming tools proposed and implemented by researchers is that there has been little consideration of the impact of the user interface on users outside the field of computer science.
In this paper we propose and implement Banger, an extension to the Parallel...
This report describes "VIGRAM" (Visual Programming) which is a program understanding and complexity metric analysis tool for Pascal programs. VIGRAM is implemented on the Macintosh as one part of the "O.S.U." (Qregon Speedcode Universe) project. With VIGRAM, the source code of a Pascal procedure can be displayed as a visual...
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...
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...
This report presents a graphical tool for implementation of the scheduling heuristics provided by Kruatrachue. The input of scheduling is a task graph and the output is a schedule in the form of a Gantt chart. The implemented scheduling heuristics are: 1) Hu's HLF (highest level first) algorithm. 2) Yu's...
Objex is an object-oriented framework for producing C++ applications through specialization of a class library and interaction model. The problem addressed in this report is that of automatically producing C++ source code from Petri Network design descriptions of applications constructed from Objex components.
The approach is to add a code...
Several problems with user interface design and implementation have been identified: (1) user interfaces are difficult and time-consuming to design and implement; (2) most user interface management systems (UIMS) are themselves difficult to use by a programmer; (3) UIMS's have not been integrated with other tools that support structured design,...
