微内核操作系统设计方法及其设计实例的比较

The Design of Microkernels and A Comparison of Three Implementations

超级计算机技术发展的趋势是大规模并行计算机,这种计算机的每个结点上运行的操作系统和一般计算机上的操作系统有极大区别。微内核操作系统提供了并行计算机所需的功能和性能,是并行操作系统的发展方向。本文讨论微内核操作系统的基本设计方法,并介绍几个典型实例:Amoeba,Mach,Chorus。

The future of supercomputing lies in massively parallel computers. There is great difference between the operating system that runs oa the nodes of these machines and those that run on the current computers. Microkernels provide the kind of functionality and performance required. We discuss in this paper three popular microkernels, Amoeba,Mach.and Chorus, to show what they can do. They are compared and contrasted in the areas of process management,memory management,and communication.
