项目摘要

We designed the central modules of the XERO distributed operating system this year. We implemented the first version of the following four modules as well.1. Dynamic multithreads management The concept of dynamic multithreads management has been refined and divided into two concepts : contexts and threads. As a result of this refinement, we can manage volatile data and persistent data in a completely transparent manner. The overall design of XERO, including the description of contexts and threads, will be published in Journal of Information Processing.We designed and implemented a new multithreads mechanism, which is based on the cooperation of user and kernel level modules. We presented this result in COMPSAC '91.2. Interprocess communication with remote procedure calls We designed the higherorder remote procedure call technique for heterogeneous distributed communication. This technique enables processes running on different hardware architectures to pass statically typed data including pointers and higher-order functions.We also implemented the distributed C language, which is an application of this technique to the C language. We will present the design issues of the distributed C language in Computer Software, the journal of JSSST.3. Persistent Object Management We designed and implemented the persistent object manager that manages data on the secondary storage based on the concept of complex object. We involved the persistent caching technique in order to speed up navigational operations among complex objects. We will present the result of these studies in IEEE Transactions on Software Engineering and the Annual Convention of IPSJ.4. Integrated Access to Objects using Tuple Spaces We designed the distributed shared repository, which a distributed information management system based on the concept of tuple spaces. We implemented a prototype of this module.

我们今年设计了Xero分布式操作系统的中央模块。我们也实现了以下四个模块的第一个版本1。动态多线程管理动态多线程管理的概念已完善并分为两个概念：上下文和线程。由于这种改进，我们可以以完全透明的方式管理挥发性数据和持久数据。 Xero的总体设计，包括上下文和线程的描述，将在信息处理杂志上发布。我们设计并实施了一种新的多线程机制，该机制基于用户和内核级别模块的合作。我们在Compsac '91 .2中提出了这一结果。与远程过程调用的交流通信我们为异构分布式通信设计了高级远程过程调用技术。该技术使在不同的硬件体系结构上运行的过程能够传递静态键入数据，包括指针和高阶功能。我们还实施了分布式C语言，这是该技术对C语言的应用。我们将介绍计算机软件中分布式C语言的设计问题，即JSSST.3。持久对象管理我们设计并实施了持久的对象管理器，该对象管理器根据复杂对象的概念在辅助存储上管理数据。我们涉及持久的缓存技术，以加快复杂对象之间的导航操作。我们将在有关软件工程和IPSJ.4年度大会的IEEE交易中介绍这些研究的结果。使用元组空间，我们设计了分布式共享存储库的集成访问对象，该存储库是基于元组空间概念的分布信息管理系统。我们实现了该模块的原型。
