Hardware Description

In April 1984, NEC announced the SX-3 Series of supercomputers, which were the fastest in the world at that time. The SX-3 Series employed state-of-the-art technology, such as ultra-LSI with 20,000 gates per chip and a delay time per gate of 70 picoseconds, and was the first Japanese-made machine to achieve a loosely coupled multiprocessor system in which up to a maximum of 4 arithmetic processors shared main memory. In this way, the system achieved the world's highest processing speed with a maximum vector operation performance of 1.37 gigaFLOPS (max.) with a single processor, and 22 gigaFLOPS (max.) with a multiprocessor.
