Steel maker Nippon Kokan KK is to market from next spring the parallel processing supercomputer developed jointly with Convex Computer Corp (CI No 2,300). NKK has been handling Convex sales in Japan since 1988 but according to Jiji Press it has sold only 10 units in the last two years. NKK’s managing director, Kazuo Kunioka, said the company hopes to gain between 20% and 30% of the Japanese parallel computer market. Cray Research Inc, Fujitsu Ltd and NEC Corp are already selling their parallel machines and Thinking Machines Corp and Intel Corp are expected to compete in the market.
