While distributed systems are now commonplace, the programming of distributed systems is still a complex task. This research focuses on simplifying the programming of distributed subsystems and applications by supporting distribution in the language. The design of an object- based language, called Emerald, and a distributed run-time system for Emerald, that facilitate the construction of distributed programs will be undertaken. The novel features of Emerald include: (1) a uniform object model that is used for programming both private local objects and shared remote objects, (2) a type system that permits multiple user-defined and compiler-defined implementations, and (3) an explicit notion of object location and mobility. A prototype Emerald system is currently operating on a small local area network of workstations.

虽然分布式系统现在很常见，但分布式系统的编程仍然是一项复杂的任务。本研究致力于通过支持语言中的分布式来简化分布式子系统和应用程序的编程。将设计一种基于对象的语言，称为Emerald，并为Emerald设计一个分布式运行时系统，以促进分布式程序的构建。Emerald的新特性包括：(1)用于编程私有本地对象和共享远程对象的统一对象模型；(2)允许多个用户定义和编译器定义的实现的类型系统；以及(3)对象位置和移动性的明确概念。一个原型Emerald系统目前在一个小型的工作站局域网上运行。
