一种面向应用的开放式并行操作系统的设计原理

Design Principle of an Application Oriented Parallel Operation System

设计了一个能降低系统自举时间，避免系统调用瓶颈、容错、动态可变以及面向应用的开放式并行操作系统．系统范围的消息传递是低延迟高效率的．把并行操作系统设计成一族程序模块，并行应用是这个族不可缺少的组成部分。

Forthcoming massively parallel computer systems are distributed memory architectures.They consist of several hundreds to thousands of autonomous processing nodes interconnected by a high speed network.A major challenge in operating system design for massively parallel architecture is to design a structure that reduce system bootstrap time,avoid bottleneck in serving system call,promote fault tolerance,is dynamically alterable,and application oriented.In addition to that ,system wide message passing is demanded to be of very low latency and very high efficiency.State of art ope rating system design must obey the maxim not to punish an application by unneeded system function.This requires to design a parallel operating system as a family of program modules,with parallel application being an integral part of that family,and motivates object orientation to achieve an efficient implementation.
