Last night, astronomers showed a breakthrough about the center of the Milky Way Galaxy - the first photo of the supermassive black hole Sagittarius A (Sagittarius A ) in the center of the Milky Way Galaxy! The photos of the black hole in the center of the Milky way are taken and calculated. Black holes do not emit light and can only be observed indirectly, while celestial bodies in the Milky way will "block the light" and "grab the mirror".
So it took more than 300 researchers around the world five years to make a fuzzy "doughnut" with a pile of photos.
According to Lenovo's official microblog, among them, Siyuan 1 of Shanghai Jiaotong University plans to generate more than 200000 images to contribute to the final formation of the photos**
Siyuan 1 is a high-performance computing cluster built by Lenovo, with up to 600 billion operations per second, and its computing power is the first in Chinese universities.
On April 10, 2021, on the 125th anniversary of Shanghai Jiaotong University, Yang Yuanqing announced that he would donate 100 million yuan to build siyuan-1 high-performance computer for his alma mater** It took only half a year to complete Siyuan Jiaotong University in Shanghai.
On the global TOP500 high-performance computer list released in November 2021, Siyuan No. 1 ranked 132nd in computing power and 12th in China's top 100 list of high-performance computing.
