Abstract

When teaching concurrency, using a process-oriented language, it is often introduced through a visual representation of programs in the form of process network diagrams. These diagrams allow the design of and abstract reasoning about programs, consisting of concurrently executing communicating processes, without needing any syntactic knowledge of the eventual implementation language. Process network di- agrams are usually drawn on paper or with general-purpose diagramming software, meaning the program must be implemented as syntactically correct program code be- fore it can be run. This paper presents POPed, an introductory parallel programming tool leveraging process network diagrams as a visual language for the creation of process-oriented programs. Using only visual layout and connection of pre-created components, the user can explore process orientation without knowledge of the un- derlying programming language, enabling a "processes first" approach to parallel pro- gramming. POPed has been targeted specifically at basic robotic control, to provide a context in which introductory parallel programming can be naturally motivated.

面向视觉过程的机器人编程

在使用面向过程的语言教授并发性时，通常通过过程网络图形式的程序的可视化表示来介绍并发性。这些图允许对程序进行设计和抽象推理，包括并发执行的通信进程，而不需要对最终实现语言有任何语法知识。过程网络图解通常画在纸上或用通用的绘图软件，这意味着程序必须被实现为语法正确的程序代码，然后才能运行。本文介绍了POPed，一个介绍性并行编程工具，利用过程网络图作为一种可视化语言来创建面向过程的程序。仅使用可视化布局和预先创建的组件的连接，用户可以在不了解底层编程语言的情况下探索进程导向，从而实现并行编程的“进程优先”方法。POPed专门针对基本的机器人控制，提供了一个可以自然地激发介绍性并行编程的环境。
