Nectar异构型多计算机系统的结构分析

ANALYSIS OF NECTAR HETEROGENEOUS MULTICOMPUTERS SYSTEM

Ｎｅｃｔａｒ系统是ＣａｒｎｅｇｉｅＭｅｌｌｏｎ大学于１９８８年研制成功的一个典型的异构型多计算机系统。本文通过分析Ｎｅｃｔａｒ系统的结构，详述了在设计多计算机系统时所面临的一些问题和解决办法。此外，以Ｎｅｃｔａｒ系统为例讨论了如何通过对软硬件的优化来减少网络通讯的开销，提高网络通讯效率。

Nectar is a heterogeneous multicomputers system developed by Carnegie Mellon University in 1988.The structure of Nectar is illustrated in this paper,and the methods to minimize the network communication overhead,including software optimizations and hardware optimizations are discussed.
