NEC Supercomputer SX System

The SX system is a high-speed, large-scale supercomputer for scientific and engineering computations. It features a peak performance of 1.3 gigaflops; a 6 nanosecond machine cycle time; 16 vector arithmetic pipelines; distributed function architecture with a control processor and an arithmetic processor; 256 million byte main memory; and 2 billion byte semiconductor extended memory. With these features, the SX system can support extremely large scientific applications.

This paper outlines LSI and packaging, vector and scalar architecture, and software for the SX system.
