In April 1983, NEC announced the supercomputer SX-2. The SX-2 was the first generation of vector supercomputer SX series and achieved 1.3GFLOPS (1.3 billion floating-point operations per second).
The SX-2 used ultra-high-speed LSI such as a logic element with a gate delay time of 250 ps and 1,000 gates per chip, and a memory element with an access time of 3.5 ns and 1 kbit per chip as semiconductor technology, and adopted the latest technology such as the first multi-chip LSI high-density package with water cooling system in Japan.
The vector architecture is suitable for efficient and high-speed processing of SIMD instructions that use a single instruction to describe repetitive operations written in DO loops. It has been used in a wide range of fields from the nuclear fusion and molecular science and weather forecasting, to the design of airplanes and automobiles.
