摘要

通过分布式通信服务的进步，新层次的软件组合成为可能。我们关注的是巨模块的组成，巨模块是自主操作和维护的大型分布式组件或计算服务器。巨型模块的构成带来了各种各样的挑战。巨型模块不一定都可以通过相同的发布协议(如CORBA、DCOM、RMI和DCE)访问。它们的并发性和可能较长的服务执行持续时间要求异步调用和收集结果。在组合大模块时，会出现新的优化需求和机会。为了应对这些挑战，我们定义了一种称为CHAIMS的纯组合语言，目前正在开发支持该语言的体系结构。在本文中，我们描述了CHAIMS，以及它是如何应对组成大模块的挑战的。

A language and system for composing autonomous, heterogeneous and distributed megamodules

New levels of software composition become possible through advances in distributed communication services. We focus on the composition of megamodules, which are large distributed components or computation servers that are autonomously operated and maintained. The composition of megamodules offers various challenges. Megamodules are not necessarily all accessible by the same distribution protocol (such as CORBA, DCOM, RMI and DCE). Their concurrent nature and potentially long duration of service execution necessitates asynchronous invocation and collection of results. Novel needs and opportunities for optimization arise when composing megamodules. In order to meet these challenges, we have defined a purely compositional language called CHAIMS, and are now developing the architecture supporting this language. In this paper we describe CHAIMS and how it meets the challenges of composing megamodules.
