Integrating the MVC paradigm into an object-oriented framework to accelerate GUI application development

Creator:: Wittel, Walter I., Jr.
Abstract:: Applications supporting a graphical user interface (GUI) are difficult to write. While existing tools can accelerate software development, they suffer from a number of problems that limit their helpfulness. They offer too little functionality, and support only a small part of the GUI software development task. They lack architectural models...

Compiling Dataparallel C for efficient execution on tightly coupled multiprocessors

Creator:: Seevers, Bradley K.
Abstract:: We describe a set of data flow techniques and code transformations that translate a single instruction stream, multiple data stream (SIMD) Dataparallel C program into a semantically equivalent single program, multiple data stream (SPMD) C program suitable for execution on shared memory multiprocessor computers, such as the Sequent Balance and...

Local search methods for job shop scheduling

Creator:: Qi, Yenong
Abstract:: Scheduling problem has both theoretical and practical interest. A great deal of research has been done in this field. In this paper we will use a local optimal search method to do job shop scheduling. This method will be compared with a constraint satisfaction method called Micro-boss. Other issues such...

Strengths and weaknesses of Dataparallel C

Creator:: S, Seetharamakrishnan
Abstract:: Dataparallel C is a SIMD style data-parallel programming language for MIMD computers. Dataparallel Chas been implemented on both shared memory (Sequent) and distributed memory (Intel and nCUBE) computers. Here we analyze the strengths and weaknesses of Dataparallel C by comparing the performance of compiled Dataparallel C programs with the performance...

Regression testing experiments and infrastructure

Creator:: Liu, Yi
Abstract:: Like other scientific fields, computer science is in great need of experimentation to support, improve, disprove and even establish theories. One area in which experimental results are highly desired involves regression testing, which is performed on modified software to provide confidence that the software behaves correctly and that modifications have...

Form systems

Creator:: Gibson, Katie
Abstract:: 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...

Porting and optimizing a routing library for Dataparallel C on the nCUBE 2 system

Creator:: Sivaramapuram, Krishna
Abstract:: Dataparallel C has been designed for various kinds of architectures and was developed jointly at University of New Hampshire and Oregon State University. This project dealt with porting the libraries to the nCUBE 2 system and helping a user compile his programs on nCUBE 2 directly from a Sun workstation...

HelpDez : colored-Petri-net-based hypermedia help system designer

Creator:: Keh, Huan Chao and Lewis, Ted G.
Abstract:: This paper describes HelpDez, a colored-Petri-net-based approach for the design, simulation, and construction of hypermedia help systems. The storage model, system capabilities, and user interface model of a hypermedia help system are examined. Colored Petri nets are chosen to model hypermedia help systems due to their graphical expressiveness and their...

Parallel state-space search for a first solution with consistent linear speedups

Creator:: Kale, L. V. and Saletore, Vikram A.
Abstract:: Consider the problem of exploring a large state-space for a goal state where although many such states may exist in the state-space, finding any one state satisfying the requirements is sufficient. All the methods known until now for conducting such search in parallel using multiprocessors fail to provide consistent linear...

Piece-wise scheduling of composite task graphs onto distributed memory parallel computers

Creator:: Lewis, Ted G.
Abstract:: Heuristics for static scheduling of task graphs using list scheduling techniques have continued to improve by adding real-world factors such as processor speed, network transmission speed, interconnection topology, and link contention considerations to the basic task graph model. Yet, the resulting schedules do not fully model program loops and branches,...

Design and code traceability using a PDL metrics tool

Creator:: Oman, Paul W. and Cook, Curtis R.
Abstract:: This paper describes an analysis tool that extracts complexity metrics from Program Design Language (PDL) as contained in design specification documents. The tool analyzes pseudocode and computes token-count metrics of PDL complexity on a module by module basis. We used the tool to measure consistency within and across modules and...

Actionbase system for manufacturing control

Creator:: Minoura, Toshimi, Choi, Sungwoon, and Robinson, Randall
Abstract:: A modern computerized manufacturing control system must manage production data, coordinate control actions, and provide user-friendly interfaces. An actionbase management system (ABMS) is a general software system that facilitates implementations of actionbase systems that provide these capabilities for different applications. Besides an ordinary data management facility, our ABMS includes action...

Implementing logic in Leda

Creator:: Pesch, Wolfgang
Abstract:: Leda is a newly evolving, strongly typed, compiled multi-paradigm programming language. This paper describes the integration of one of its supported paradigms, the logical (or relational) paradigm, into the language and the current implementation. It also describes implementational aspects of enumerated types and gives a variety of example programs that...

Implementing Leda : objects and classes

Creator:: Shur, Jim
Abstract:: Leda is a strongly typed, compiled, multiparadigm programming language. This paper describes various implementation concerns which arose from the experience of writing a Leda compiler as part of the Leda research team. These include aspects of run-time representation, symbol-table information, and code generation. The paper concentrates on objects and classes....

System Performance Displayer : a performance monitoring tool

Creator:: Po, Wang-ping, Lewis, Ted G., and Thakkar, Shreekant
Abstract:: As UNIX operating system's popularity increases, so arises the greater need for performance data gathering and resources management of the systems. Contrary to the expectation of UNIX users, however, there is only a limited set of tools available, and these tools are difficult to correlate data from different sources and...
