适用于分布式程序设计的图示化模型

A Visual Model for Distributed Programming

ＶＭＤＰ（ｖｉｓｕａｌｍｏｄｅｆｏｒｄｉｓｔｒｉｂｕｔｅｄｐｒｏｇｒａｍｍｉｎｇ）模型是一个基于图标的面向分布式程序设计的图示化模型．它用图标表示分布式系统中的对象及其控制，例如，用车辆、路口和红绿灯等图标分别表示进程、资源和进程控制，从而使分布式系统中进程之间的同步、异步、互斥、共享等协调关系变得十分直观和易于理解．ＶＭＤＰ模型可以广泛应用到分布式系统模型、网络程序设计、并行程序设计和分布式程序设计等领域．

VMDP is a visual model for distributed programming based on icons, which is used to illuminate the objects and the controls in a distributed system. With VMDP, a process is represented by a vehicle, a resource by a crossroad, and the coordination among processes by the traffic light. The coordination relations among processes and controls such as synchronization and mutual exclusion are understandable and readable in VMDP. VMDP devotes itself to building distributed system model, network programming, and parallel/distributed programming as well.
