my country’s first petaflop supercomputer is named “Tianhe-1”. "Tianhe-1" is China's first gigabit supercomputer. The supercomputer's peak performance speed can reach 1,206 teraflops of double-precision floating point numbers per second, while LINPACK's measured performance speed reaches 563.1 teraflops per second. On October 29, 2009, Tianhe-1, the first domestic gigabit supercomputer, was unveiled in Changsha, Hunan.

my country's first petaflop supercomputer isTianhe-1
On October 29, 2009, as the first domestically produced The gigabit supercomputer "Tianhe-1" was unveiled in Changsha, Hunan; the second phase system (TH-1A) was upgraded at the National Supercomputing Center in Tianjin in August 2010.The "Tianhe-1" supercomputer uses the "Dragon" chip independently developed by China. With a peak speed of 1,206 teraflops per second and Linpack's measured performance of 563.1 teraflops running speed, the supercomputer named "Tianhe-1" ranked first in the top 100 Chinese supercomputers announced on the same day. , also made China the second country in the world to independently develop a gigabit supercomputer after the United States. (One trillion equals one trillion)
The peak performance speed of this supercomputer can reach 1206 trillion double-precision floating point numbers per second, while the measured performance speed of LINPACK reaches 563.1 trillion times per second. The above two measured performance data of the computer system have been submitted to the statistical organization responsible for ranking the TOP500 international supercomputers. According to the performance test data of this supercomputer in June 2009, "Tianhe-1" "The measured performance of the supercomputer can be ranked fourth in this year's TOP500 rankings, and the peak performance of the "Tianhe-1" supercomputer can be ranked third in this year's TOP500 rankings. This speed means that if the "Tianhe-1" supercomputer is used to run calculations for one second, its running speed is equivalent to 88 years of continuous calculations by 1.3 billion people across the country. If you use Tianhe-1 to calculate for one day, it is equivalent to using a microcomputer that is currently the mainstream model to continuously run calculations for 160 years. The storage capacity of the "Tianhe-1" supercomputer is equivalent to the combined book collections of four national libraries.
After Tianhe-1 was put into use in 2010, it has made remarkable achievements in aerospace, weather forecasting, climate forecasting and marine environment simulation. China will use supercomputer technology to monitor haze weather.
On August 13, 2015, affected by the August 12 Tianjin Binhai New Area explosion, the National Supercomputing Tianjin Center building where Tianhe One is located was damaged. The normally operating Tianhe One was manually shut down to ensure safety. On August 17, 2015, after more than four days of artificial power outage, the "Tianhe-1" supercomputer at the National Supercomputing Center in Tianjin officially resumed operation after power-on testing on the afternoon of the 17th.
In January 2019, "Tianhe-1" has been operating at full capacity for five consecutive years.
On January 16, 2019, it was learned from the National Supercomputing Tianjin Center and the second session of the 17th Tianjin Municipal People’s Congress being held here that starting from 2014, the my country's first gigabit supercomputer "Tianhe-1" has been operating at full capacity for five consecutive years. There are more than 1,400 concurrent online computing tasks every day, and more than 3.35 million tasks are completed every year. It serves more than 3,000 teams and units across the country, and has brought economic benefits to enterprises totaling nearly 10 billion yuan.
