Reference news, June 22 Japanese media say year two supercomputer speed world "TOP500" ranking 20th, developed by the China National Center for computer engineering new supercomputer "Kamui Taihu light" won the top spot.
According to Japan's Asahi Shimbun reported on June 21, it is reported that the processor is also known as the heart of in the computer by the Chinese independently developed "pure domestic product."
Kamui Taihu light speed of 930 million times per second, was the defending champion, the United States produced Intel processors in China "Tianhe 2nd" super computer 3 times. Also falling from 4th to 5th in the ranking of Japan supercomputer "Jing" (RIKEN) 9 times.
Prior to this, China has been the introduction of United States production processor Assembly. However, the concern for military use of the United States Government restricts exports to China last year. China's independent research and development in the use of "many-core processor" (many core) this latest technology. Centre for computational science education in Kobe University professor Xiao Liu Yifu said: "many-core processor development needs with cutting-edge technology. Success came faster than expected. United States restrictions on exports probably also played a role in promoting technology development. "
Japan, Ministry of science, culture planning in 2020, "Jing" successor species "Post Beijing" is put into operation. Total funding will reach 130 billion yen ($ 8.216 billion yuan), the target speed is 100 times in Beijing, but the Japanese side did not aim at the "world's first" position, but adopted a policy of importance to energy saving and easy to use.

日媒：中国超级计算机称霸全球拜美国所赐|超级计算机_新闻资讯

参考消息网6月22日报道 日媒称，一年两度竞争超级计算机计算速度的世界“TOP500”排名已于20日发表，由中国国家并行计算机工程中心新研制的超级计算机“神威太湖之光”问鼎榜首。
据日本《朝日新闻》6月21日报道，据悉，该计算机中被称为心脏部分的处理器也是由中国自主研发的“纯国产产品”。
神威太湖之光的计算速度为每秒9.3亿亿次，是上届冠军、使用了美国英特尔公司出品处理器的中国“天河2号”超级计算机的3倍。同时也是在本次排名中从第4跌落至第5的日本超级计算机“京”（理化学研究所）的9倍。
在此之前，中国一直引进美国生产的处理器进行组装。然而，担忧进行军事利用的美国政府于去年限制了对中国的出口。中国在此次的自主研发中采用了“众核处理器”（many core）这一最新技术。神户大学计算科学教育中心特聘教授小柳义夫表示:“众核处理器的开发需具备尖端技术。成功来得比预想要快。美国限制出口的措施大概也起到了推动技术开发的作用” 。
日本方面，文部科学省正计划在2020年度，将“京”的后继机种“Post 京”投入运行。总经费将达1300亿日元（约合人民币82亿1600万元），目标计算速度虽为京的100倍，但日方并未瞄准“世界第一”的名次，而是采取了重视节能与便于使用的方针。
