Hitachi announced the SR8000 supercomputer in May 1998. The SR8000 featured Hitachi’s own RISC microprocessors developed with 0.25-micron CMOS technology and a multidimensional crossbar network that delivered high performance in several transfer patterns.
By combining the powerful performance of conventional vector-based supercomputers with the inherent scalability of parallel computers, the SR8000 could be scaled by a factor of 32, from 32 gigaFLOPS to 1024 gigaFLOPS, in terms of theoretical peak performance.
Hitachi also achieved high-speed performance on par with vector processors by using an architecture known as cooperative microprocessors in a single address space (COMPAS), which simultaneously drives multiple microprocessors making up a node at high speeds.
