NEC SX-9
From Wikipedia, the free encyclopedia
The SX-9 is a supercomputer built by NEC Corporation. The SX-9 Series implements an SMP system in a compact node module and uses an enhanced version of the single chip vector processor that was introduced with the SX-6. The NEC SX-9 processors run at 3.2 GHz, with eight-way replicated vector pipes, each having two multiply units and two addition units; this results in a peak vector performance slightly greater than 100 GFLOPS. Up to 16 CPUs and 1TB of memory may be used in a single node. Each node is packaged in an air-cooled cabinet, similar in size to a standard 42U computer rack. The SX-9 series ranges from the single-node SX-9/B system with 4 CPUs to the maximum expansion stage with 512 nodes, 8,192 CPUs, and 970 TFLOPS peak performance. There is up to 4 TB/s shared memory bandwidth per node and 2 x 128 GB/s node interconnect bandwidth. The operating system is NEC's SUPER-UX Unix-like OS.
The SX-9 has the world's fastest vector CPU core. A fully equipped system with 512 nodes would be the world's fastest vector supercomputer at the time of release.
