Abstract
The strong request of more speed-up of CPU and larger-scale capacity of memory exists among scientists, engineers and others. In response to this request, the announcements of home-made supercomputers (Fujitsu in July and Hitachi in August) succeeded last year. This movement has evoked a large echo in USA. The world situation on the very high-speed scientific computers is becoming active. In Japan, scientific calculation's field enters into the age of the supercomputer in the coming autumn.
In this article, we try to survey the movement and characteristics of the supercomputers briefly.
