The primary terget of this research was the development of distributed operating system XERO with high openness. An open operating system has an ability to share communicate data with other systems regardless of the obstacles of the real world, such as differences of hardware architectures, data representations, communication protocols, and programming models. The XERO operating system has three outstanding features for high openness : high-performance program execution mechanism through "dynamic" multithreading, flexible inter-thread communication through remote procedure calls, a mechanism for managing data on the secondary storage as persistent objects, and uniform handling of inter-thread communication and persistent objects. The dynamic multithreading was implemented, and substantial performance improvement has been taken after the performance measurement and reconstruction of implementation and design. Through the investigation of theoretical backgrounds, we realized remote procedure calls in XERO with powerful expressive power, that is, any statically typed data and higher-order functions can be transferred. We are integrating the modules that we have implemented for two years, and implemented the UNIX compatibility. We are running UNIX utilities on XERO without re-compilation nor re-link. The persistent object management system provides a simple type system for persistent programming. Several technology was investigated for efficient implementation of persistent storage.

这项研究的主要推销是开发分布式操作系统Xero的开放度很高。开放操作系统具有与其他系统共享数据的能力，无论现实世界的障碍如何，例如硬件体系结构，数据表示，通信协议和编程模型的差异。 Xero操作系统具有三个出色的高度开放性功能：高性能程序执行机制，通过“动态”多线程，通过远程过程调用灵活的线程间读取通信，一种用于将次要存储的数据作为持久对象管理数据的机制，以及统一的跨性别对象的操作，并统一处理线程相互阅读的通信和持久的对象。实施了动态多线程，并在实施和设计的性能测量和重建后进行了大量的性能改进。通过对理论背景的调查，我们意识到具有强大表达能力的Xero中的远程过程调用，也就是说，可以传输任何静态键入数据和高阶功能。我们正在整合已经实施了两年的模块，并实施了UNIX兼容性。我们在Xero上运行UNIX实用程序，而无需重新编译或重新链接。持续的对象管理系统提供了一个简单的类型系统，用于持久编程。研究了几项技术以有效地实施持续存储。
