Description
The Cray SV1 is a vector processor supercomputer from the Cray Research division of Silicon Graphics introduced in 1998. The SV1 has since been succeeded by the Cray X1 and X1E vector supercomputers. Like its predecessor, the Cray J90, the SV1 used CMOS processors, which lowered the cost of the system, and allowed the computer to be air-cooled. The SV1 was backwards compatible with J90 and Y-MP software, and ran the same UNIX-derived UNICOS operating system. The SV1 used Cray floating point representation, not the IEEE 754 floating point format used on the Cray T3E and some Cray T90 systems.
