面向流场计算的专用超级计算机体系结构研究

 本文在对流体力学等一类大型计算问题的并行计算模型进行分析的基础上,提出了一种可以实现大规模并行处理的专用超级计算机体系结构方案。该系统由一台宿主机和一个多计算机阵列组成一台个人超级计算机。利用专用性,减小复杂性,提高并行性是系统的主要特色。系统采用二维超环结构作为计算机结点之间的互连结构,反映了计算中数据交换的局部性特点,具有好的通信性能。每个计算机结点本身又采用流水线向量处理结构,从而将高层次的多机并行与低层次的向量处理相结合,实现了大规模的并行计算。本文讨论了系统的软、硬件结构并研究和评价了通信性能。

ARCHITECTURAL STUDY OF A SPECIAL-PURPOSE SUPERCOMPUTER FOR FLUID FIELD COMPUTATION

After a dcsor;p;.:on of the parallel computation model for the class of large-scale commuting problems in the field of fluid dynamics?a specialized supercomputer architecture "which realizes massive parallelism is proposed in 'his paper. The architecture proposed is a personal supercomputer consisting oi a host system and an array oi computing nodes.The architecture achieves reduced complexity, increased parallelism by taking advantage of the special purpose feature of the system. The interconnection topology reflects the locality property of data exchanges (luring computation, Knch computer node itself has a pipelined vector processor containing two independent pipelines. Thus the system combines the parallelism between computing nodes at a higher level with the vector processing capability at a lower level to increase computing power significantly. The special purpose feature and the existence of the host reduce the software complexity. The issues in hardware, software and programming are discussed and the communication performance is studied and evaluated in the paper.
