THE PROGRAMMABLE NETWORK PROTOTYPING SYSTEM

COMPUTER 1989年第5期22卷 67-76页

The programmable network prototyping system (PNPS) uses a collection of reusable hardware modules that implement generic communications functions such as transmission, reception, signal propagation, and pattern matching. These modules are interconnected and configured to emulate a variety of communication networks whose behavior can be monitored under different load conditions. The user specifies a network as a set of interacting components using available software tools. These tools are accessible within a prototyping environment that includes a control system for configuring the hardware modules and interconnecting them according to the component specifications. Previously designed components are stored in a library and can be used to specify new networks. Although PNPS is designed to provide a prototyping environment for communication networks, some of the basic ideas can be useful in other contexts

Comparing Block-Based programming Models for Two-Armed Robots

Modern industrial robots can work alongside human workers and coordinate with other robots. This means they can perform complex tasks, but doing so requires complex programming. Therefore, robots are typically programmed by experts, but there are not enough to meet the growing demand for robots. To reduce the need for experts, researchers have tried to make robot programming accessible to factory workers without programming experience. However, none of that previous work supports coordinating multiple robot arms that work on the same task. In this paper we present four block-based programming language designs that enable end-users to program two-armed robots. We analyze the benefits and trade-offs of each design on expressiveness and user cognition, and evaluate the designs based on a survey of 273 professional participants of whom 110 had no previous programming experience. We further present an interactive experiment based on a prototype implementation of the design we deem best. This experiment confirmed that novices can successfully use our prototype to complete realistic robotics tasks. This work contributes to making coordinated programming of robots accessible to end-users. It further explores how visual programming elements can make traditionally challenging programming tasks more beginner-friendly.

IFS - A TOOL TO BUILD APPLICATION SYSTEMS

引用

IEEE SOFTWARE 1990年第4期7卷 29-36页

作者： VO, KP AT and T Bell Laboratories Inc. USA

The interpretive frame system (IFS), a tool for building application systems, is presented. IFS separates high-level design and user-interface programming from domain-specific programming. It offers a language suitable for implementing systems of interconnected tasks, simplifies the construction of sophisticated but easy-to-use user interfaces, and increases tool reuse in system construction. A system built with IFs is called a frame system, and it consists of four layers-the user interface, system structure, computational functions, and data architecture-which are described. The IFS language and programming environment are also described. A programming example is given. Reuse and prototyping are discussed.

PERSPECTIVES ON ARTIFICIAL-INTELLIGENCE programming

引用

SCIENCE 1986年第4741期231卷 951-957页

Programs are judged not only by whether they faithfully carry out the intended processing but also by whether they are understandable and easily changed. programming systems for artificial intelligence applications use specialized languages, environments, and knowledge-based tools to reduce the complexity of the programming task. Language styles based on procedures, objects, logic, rules, and constraints reflect different models for organizing programs and facilitate program evolution and understandability. To make programming easier, multiple styles can be integrated as sublanguages in a programming environment. programming environments provide tools that analyze programs and create informative displays of their structure. Programs can be modified by direct interaction with these displays. These tools and languages are helping computer scientists to regain a sense of control over systems that have become increasingly complex.

VISTA - A USER INTERFACE FOR A DISTRIBUTED OBJECT-ORIENTED SOFTWARE ENGINEERING ENVIRONMENT

引用

SOFTWARE ENGINEERING JOURNAL 1992年第1期7卷 25-34页

作者： RODDEN, T SAWYER, P SOMMERVILLE, I UNIV LANCASTER DEPT COMPLANCASTER LA1 4YRENGLAND

This paper describes a prototype user interface for a distributed software engineering environment, where the components of the environment are autonomous agents with some inherent decision-making capabilities. Agents may be distributed across a local- or wide-area network. Two forms of interaction are supported;namely, direct manipulation and message passing. Synchronous interaction is supported via the direct manipulation of system objects. Asynchronous interaction is managed by a central server agent, distributing electronic mail messages to the appropriate human or automated agents. The functionality of the system is illustrated by examples drawn from the domain of software development.

Language and library support for practical PRAM programming

引用

PARALLEL COMPUTING 1999年第2期25卷 105-135页

作者： Kessler, CW Träff, JL Univ Trier FB Informat 4 D-54286 Trier Germany Tech Univ Munich Lehrstuhl Effiziente Algorithmen D-80290 Munich Germany

We investigate the well-known Parallel Random Access Machine (PRAM) model of parallel computation as a practical parallel pl programming model. The two components of this project are a general-purpose PRAM programming language, called Fork95, and a library, called PAD, of fundamental, efficiently implemented parallel algorithms and data structures. We outline the main features of Fork95 as they apply to the implementation of PAD, and describe the implementation of library procedures for prefix-sums and sorting. The Fork95 compiler generates code for the SB-PRAM, a hardware emulation of the PRAM, which is currently being completed at the University of Saarbrucken. Both language and library can immediately be used with this machine. The project is, however, of independent interest. The programming environment can help the algorithm designer to evaluate the practicality of new parallel algorithms, and can furthermore be used as a tool for teaching and communication of parallel algorithms.

The ParaScope parallel programming environment, developed to support scientific programming of shared-memory multiprocessors, includes a collection of tools that use global program analysis to help users develop and debug parallel programs. This paper focuses on ParaScope's compilation system, its parallel program editor, and its parallel debugging system. The compilation system extends the traditional single-procedure compiler by providing a mechanism for managing the compilation of complete programs. Thus, ParaScope can support both traditional single-procedure optimization and optimization across procedure boundaries. The ParaScope editor brings both compiler analysis and user expertise to bear on program parallelization. It assists the knowledgeable user by displaying and managing analysis and by providing a variety of interactive program transformations that are effective in exposing parallelism. The debugging system detects and reports timing-dependent errors, called data races, in execution of parallel programs. The system combines static analysis, program instrumentation, and run-time reporting to provide a mechanical system for isolating errors in parallel program executions. Finally, we describe a new project to extend ParaScope to support programming in Fortran D, a machine-independent parallel programming language intended for use with both distributed-memory and shared-memory parallel computers.

A description is given of MicroScope, a knowledge-based environment with tools that directly help programmers understand and modify complex programs. MicroScope is a collection of tools that share a common knowledge base and user interface and that run in a programming environment with many other tools. The features it provides are examined, namely, incremental support, annotations, constraints, dynamic analysis, history and program slices, and location of bugs. The knowledge base is described. The current MicroScope prototype is presented, and the lessons learned from it are discussed.
