摘要
并行计算机系统中网络对整个系统性能影响起到了关键作用,而SPMD并行计算机系统在科学计算,特别是航空航天中比较普及,因此开发了通用SPMD并行系统结构性能评价模拟系统。该文描述的面向对象网络模拟系统是该模拟环境的一部分,采用伪汇编代码的算法程序作为输入,通过配置结构参数、与系统提供的描述不同结构的伪汇编指令函数库编译链接,达到对不同层次细节、不同侧重部件模拟研究的目的。与同类研究相比,本文的研究具有更通用的特点,能够方便地构造不同的动态和静态网络,特别是能够对可重构的多级互连网络进行性能评价研究。
Network has pivotal effect on entire system performance in parallel computer system, and SPMD parallel computer system has been used prevalently in science computing and especially in aeronautics ＆ astronautics, so performance evaluation simulation system for universal SPMD parallel architecture has been developed. The object-oriented network simulation system in this paper is one part of simulation environment above, using algorithm program of pseudoassemble code as input, configuring architecture parameters, compiling and linking with function library of pseudoassemble code provided by the system to describe different architectures so as to simulate different level and different part of the system. Compared with similar research, ours have the character of more general purpose, which can construct different static and dynamic network expediently, especially could be used to do performance evaluation research on the reconfigurable multilevel interconnected network.
