据美刊最近报道,克雷X-MPEA/18se计算机是克雷公司推出的另一新系统。该公司目前为用户提供三种入口水平的“se”系统,各有400万字、800万字及1600万字的存储容量,其价格分别为250万美元、290万美元与350万美元。所有的克雷X-MPEA/se计算机的时钟周期均为8.5毫微秒,较之先前这种类型的计算机的时钟周期(10毫微秒)减少了15%。此外,所有的克雷X-MPEA/se计算机都可用与克雷Y-MP系统相容的模式运行,因此备有这类计算机的用户可过渡到克雷Y-MP结构上。克雷Y-MP8主机现在已有供应,而克雷Y-MP 2及克雷Y-MP4主机将于1989年第三季度进入市场。但是,能使这三种主机发挥其最大功能的结构要到1990年的第二季度才能问世。在那之前订购了克雷Y-MP系统的用户可在相应结构能获得之时把他们的系统扩展到其最大能力。
According to a recent report from the US Journal, the Cray X-MPEA/18se computer is another new system launched by Cray. The company currently provides users with three entry-level “se” systems, each with 4 million words, 8 million words and 16 million words of storage capacity, with prices of 2.5 million USD, 2.9 million USD and 3.5 million USD respectively. All Cray X-MPEA/se computers have a clock cycle of 8.5 nanoseconds, which is a 15% reduction compared to the previous computer clock cycle (10 nanoseconds). In addition, all Cray X-MPEA/se computers can be operated in a mode compatible with Cray Y-MP systems, so users equipped with such computers can transition to Cray Y-MP structures. The Cray Y-MP8 mainframe is now available, while the Cray Y-MP 2 and Kray Y-MP4 mainframes will enter the market in the third quarter of 1989. However, the structure that enables these three types of hosts to perform their maximum functions will not be available until the second quarter of 1990. Users who had previously ordered the Cray Y-MP system could extend their system to their maximum capacity when the corresponding structure was available.
