The SX-6 is a NEC SX supercomputer built by NEC Corporation that debuted in 2001; the SX-6 was sold under license by Cray Inc. in the U.S. Each SX-6 single-node system contains up to eight vector processors, which share up to 64 GB of computer memory.
The vector unit performs add/shift, multiply, divide and logical operations.
The scalar unit can decode, issue and complete four instructions per clock cycle.
