制造CRAY-1巨型机的克雷公司于1979年10月宣布一种S系列。这个系列有12种型号,第一台机器计划于1980年四季度交货。S系列机采用具有标量和向量处理能力的流水线结构。CPU与CRAY-1机的相同,字长64位,机器周期12.5ns。软件与CRAY-1机相容,用CRAY COS操作系统,并有汇编程序和FORTRAN编译程序。如果CRAY-1机的用户再加装这个系列的机器就可以作为现有系统串联的CPU,加强计算能力。与CRAY-1机相比,S系列机主要是存贮容量大(包括外存)和输入/输出处理能力强。
Cray, maker of the CRAY-1 supercomputer, announced a S-Series in October 1979. This series has 12 models, the first machine scheduled for delivery in the fourth quarter of 1980. S Series machines use a pipeline structure with scalar and vector processing capabilities. CPU and CRAY-1 machine the same word length 64, machine cycle 12.5ns. The software is compatible with the CRAY-1, with the CRAY COS operating system, with assembler and FORTRAN compiler. If CRAY-1 machine users to re-install this series of machines can be used as the existing system in series CPU, to strengthen the computing power. Compared with the CRAY-1 machine, S series machine mainly storage capacity (including memory) and input / output processing capability.
