前言当前世界上的大型计算机和巨型计算机的结构,一般都是由多个独立的功能部件、多个前沿寄存器、多个后援寄存器、多个模块的大内存和复杂的控制逻辑构成的。使用的元器件和印制线,网线以及焊点的数量都是惊人的。如YH—1/230主机元器件约20万片,印制线约千万条底板网线12万条焊点约200万个,由此可见,这么大的一个巨型计算机的可维性设计是何等的重要。另外,大型计算机、巨型计算机它们有速度快、精度高、功能强等多方面的优点,目前大都应用在如核物理、航天器设计、石油勘探油藏 Preface The structure of the world’s major computers and giant computers are generally composed of a number of independent features, multiple leading registers, multiple backing registers, large memory of multiple modules and complex control logic. The use of components and printed lines, network cables and the number of solder joints are amazing. Such as YH-1/230 mainframe components of about 20 million, printed lines about 10 million network cable 120000 solder joints of about 2000000, we can see that such a large computer dimensional design is how importance. In addition, large computers, supercomputers they have the advantages of speed, high precision, strong function and many other aspects, at present mostly used in such as nuclear physics, spacecraft design, oil exploration reservoir
