YFSIM核库系统设计与实现

Design and Implementation of YFSIM Kernels Library System

多处理机系统是当今计算机研究和开发的热门。多处理机上软件研制的一个难题是：系统怎样才能自动产生高度并行运行代码。本文中我们提出一种模板式的核流水线设计方法，使多个处理机的指令系统，转化为虚拟的单处理机宏指令（核库）。我们用这种方法在银河仿真Ⅱ型机（ＹＨ—Ｆ２）上设计并实现ＹＦＳＩＭ核库，它包括完成各种仿真计算任务的１０００个多个核代码程序（宏指令）。ＹＦＳＩＭ编译器采用上、下有关文法面向核库进行定义，分析和制导翻译，能够自动产生多个处理机的复合指令，实现多个运算的并行处理，充分发挥了硬件传送，加载，运算等各种指令的并发操作功能和多处理机并行功能。

Multiproeessor systems are in great demand of research and development actvity for computerat present.It is a difficult problem on multiprocessor software how to produce high parallel codes auto-matically.In this paper a design method of the template kernels pipeline has been put fomard.It changcsthe multiprocessor instruction system into the macroinstruction set of a virtual single proeessor. By meansof this method YFSIM Kernels Library have been designed and implemented at the Yin He SimulationComputer II(YH F2).The Kemels Library consists of a thousand and more kemels code(macroinstruction set)to accomplish simulation computation of all kinds. YFSIM compiler can procducecompound instruction of multiproeessor kernels orientcd definition,analysis and translation,to achieveparallel processing of multi calculations,and to bring the parallel feature of multiproeessor hardware intofull play。
