摘要

自定义和扩展操作系统的技术对分布式计算和并行编程领域的系统架构产生了越来越大的影响。即使传统的适应方法仅限于用户级，现代的操作系统也不能没有内核支持。因此，必须重新定义微内核体系结构的概念和结构，以满足当今和未来应用程序的需求。我们提出了一种新的可定制的底层操作系统架构——Dycos内核。讨论了微内核的定制需求，并描述了内核的基本概念。Dycos是一种基于对象的方法，提供了一个操作工具箱来构建用户可定义的内核结构组合。Dycos方法已经在Solaris 2.5.1平台上进行了评估。

Dycos-a customizable kernel architecture supporting distributed operating environments

Techniques of customizing and extending operating systems (OSs) have a growing impact on system architectures in the field of distributed computing and parallel programming. Even if traditional methods of adaption have been limited to the user-level, modern OSs cannot do without kernel support. Hence concepts and structures of microkernel architectures must be redefined to meet the requirements of today's and future applications. We propose a new customizable low-level OS architecture-the Dycos kernel. We discuss customization demands on microkernels and describe the basic kernel concept. Dycos is an object-based approach providing a toolbox of operations to build user-definable compositions of kernel structures. The Dycos approach has been evaluated on a Solaris 2.5.1 platform.
