SX-8

The SX-8 is a vector supercomputer with a peak processing performance of 65 TFLOPS. The single-node model (includes up to eight CPUs) achieves a peak vector performance of 128 GFLOPS, while the multi-node model reaches a peak performance of 65 TFLOPS when configured with 512 nodes. In addition, a 262 TB/s high peak data-transfer rate between CPU(s) and memory is realized. The vector processor is integrated into a single chip by applying CMOS technology with 90-nm copper interconnects and LSI design technology. Pipelines of the vector unit (the central portion of a vector processor) operate at a 2 GHz clock frequency. The basic software, “SUPER-UX,” maintains upward compatibility with the existing SX series and achieves scalability expansion due to I/O processing and MPI.
