Cray is the father of supercomputers, but thanks to HP,IBMThe share of the world's top 500 supercomputers has declined significantly, but in recent years there has been a trend to regain the supremacy of supercomputers.
Seymour Cray founded its own company Cray Research Inc. in 1972, and then the company's first product, Cray-1 supercomputer, became the fastest computer at that time.Subsequent derivatives of this product include Cray-2 and Cray-3.At the same time, they also started a parallel project Cray X-MP under the leadership of Chen Shiqing, Steve Chen, until Chen left in 1987.
Cray releasedTitanThe supercomputer became the fastest system at that time until it was pulled down by Tianhe 2 in 2013.

On November 19, 2013, the 42nd Global Supercomputer 500 Ranking List was compiled by“Tianhe No.2”After winning the laurel half a year ago, it won the first prize again. The second place is still Titan, and the only new top ten is the sixth place. The "Piz Daint" from the Swiss National Supercomputing Center (CSCS) is based on Cray XC30 supercomputing system, equipped with Intel Xeon E5-2670 2.6GHzEight core processorNVIDIA Tesla K20x accelerated computing card, with a peak performance of 7.79PFlops and a maximum performance of 6.27PFlops.This is the fastest supercomputer in Europe, and also the most efficient one among the top ten. The overall power consumption is only 2.33 MW, and the energy efficiency is 2.7 GFlops/W.[1]
From the perspective of manufacturers,IBMIt is still the manufacturer with the largest number of supercomputers in the world's top 500. About 42% of supercomputers are developed and manufactured by it, followed by HP and Cray, whose shares are 31% and 6% respectively.
From the perspective of the number of supercomputers owned by the country, the United States still has the largest number of Fortune 500 supercomputers, with a total of 256 Fortune 500 supercomputers;China ranked second, with 62 supercomputers among the top 500;Then came Germany, Britain, Japan and France, which have 30, 27, 26 and 25 supercomputers respectively.
