基于CMP的高密度计算机多目标设计方法

面向高端应用的高效能计算机一般具有高性能、高集成度、高热密度、高复杂性的特点，其研制是一项复杂的系统工程。每一环节，存在功能、性能、可靠性等相互制约但需同时兼顾的多个目标。在实践中这些方面的权衡设计如何以有序的方式展开，是一个亟待解决的关键问题。提出了可靠性与功能、性能权衡的设计方法，并应用到一款基于国产多核处理器的16路高密度计算机的自主研制中，软件仿真分析和系统实测验证了该权衡设计方法的有效性。

Multi-objective design methodology for CMP-based high-density computers

A high-end application-oriented high productivity computer generally features high-performance,high integration,high heat density and high complexity.As a complex system engineering,its design flow involves several stages,and at each stage there are several targets,such as functionality,performance,reliability,which are mutual restraint but should be taken into account simultaneously.In practice,it is a key issue to arrange the collaborative design on these aspects in an orderly manner.A co-design methodology is presented and is applied to the design of a 16-way high density computer based on domestic Godson 3A central processing unit,and the effectiveness of which is verified through software simulation and real test.
