从国外引进的CDC CYBEK172计算机系统,自1977年中旬在我国现场安装验收之后,截至1978年底已连续加电开机13个月。处理了几万公里的石油地震勘探资料。现将设备的运行情况做一概要介绍,供有关方面参考。一、交机率统计交机率计算公式: P=(T-t/T(%) T——总开机时间 t=t_d+t_(PM)+t_(EM)为由下列原因引起的计算机系统运行中断的时间。 t_d——操作系统被破坏而中断计算机工作的时间。按平均统计计算,取t_d=n×0.5小时。 n——系统破坏的次数
The CDC CYBEK172 computer system introduced from abroad has been powered on continuously for 13 months as of the end of 1978 after it was installed and checked in our country in mid-1977. Handled tens of thousands of kilometers of oil seismic exploration data. Now the operation of the equipment to make an overview of the information for the parties concerned. First, the intersection of delivery and the intersection of rate and the intersection of statistics and the intersection of turn over rate and calculation formula: P = (Tt / T (%) T - The total turn on time t = t_d + t_ (PM) + t EME It is the intersection of computer and the intersection of system and operation interrupted time . T_d-- operating system is broken and interrupt the computer work time. According to the average statistical calculation, take t_d = n × 0.5 hours. N - the number of system damage
