Description
The HITAC S-810 is a vector supercomputer developed, manufactured and marketed by Hitachi. The first models, the S-810/10 and S-810/20, were announced in August 1982, making the S-810 was the second of the first three Japanese supercomputers, following the Fujitsu VP-200, which was announced July 1982, but predating the NEC SX-2, which was announced in April 1983. The S-810 was Hitachi's first supercomputer, although the company had previously built a vector processor, the IAP. The first system shipped was a top-end S-810/20 model, which was delivered to the University of Tokyo's Large Computer Center in October 1983. The S-810 was succeeded as Hitachi's top-end supercomputer by the HITAC S-820 announced in July 1987.
