Emerald: A Language for Distributed Programming

虽然分布式系统现在很常见， 分布式系统仍然是一项复杂的任务。 本研究着重于 简化分布式子系统和应用程序的编程 支持语言的分发。 一件物品的设计- 的语言，称为Emerald，和一个分布式运行时系统， Emerald，促进分布式程序的构建， 进行。 Emerald的新功能包括：（1）统一 一种对象模型，用于对私有本地对象和 和共享远程对象，（2）一个类型系统，允许多个 用户定义和编译器定义的实现，以及（3）显式的 对象位置和移动性的概念。 Emerald系统的原型是 目前在一个小型工作站局域网上运行。

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.
