supercomputers, which was developed, manufactured and marketed by Hitachi. Announced in April 1992, the family succeeded the HITAC S-820. The S-3000 family comprised the low-end and mid-range S-3600 models and the high-end S-3800 models. Unlike Hitachi's previous generations of supercomputers, the S-3000 family was marketed outside Japan. The S-3600 was an improved version of the S-820 implemented in more modern semiconductor technology. The S-3800 was a new design, differing significantly from the previous generations. It was a ''parallel vector processor'' and supported one to four vector processors. In 1994, the S-3000 family was complemented by an MPP machine that used superscalar microprocessors, the SR2001. Hitachi eventually discontinued development of vector supercomputers in favor of this approach. The S-3000 family was replaced in 2000 by the SR8000, making it the last vector supercomputer from Hitachi. The CPU architecture of HITACHI S-3800 Series was based on

IBM System/370 The IBM System/370 (S/370) is a model range of IBM mainframe computers announced on June 30, 1970, as the successors to the System/360 family. The series mostly maintains backward compatibility with the S/360, allowing an easy migration path ...

, and compatible with Hitachi's mainframe systems. It supported two operating systems: OSF/1 Unix and Hitachi's own VOS3 (a fork of IBM MVS).
