Tianhe-I
Tianhe-I, Tianhe-1, or TH-1 ((中国語:天河一号), ; ''Sky River Number One'') is a supercomputer capable of an Rmax (maximum range) of 2.5 petaFLOPS. Located at the National Supercomputing Center in Tianjin, China, it was the fastest computer in the world from October 2010 to June 2011 and is one of the few Petascale supercomputers in the world.
In October 2010, an upgraded version of the machine (Tianhe-1A) overtook ORNL's Jaguar to become the world's fastest supercomputer, with a peak computing rate of 2.507 petaFLOPS. In June 2011 the Tianhe-1A was overtaken by the K computer as the world's fastest supercomputer, which was also subsequently superseded.
Both the original Tianhe-1 and Tianhe-1A use a Linux-based operating system.
On 12 August 2015, the 186,368-core Tianhe-1, felt the impact of the powerful Tianjin explosions and went offline for some time. Xinhua reports that "the office building of Chinese supercomputer Tianhe-1, one of the world's fastest supercomputers, suffered damage." Sources at Tianhe-1 told Xinhua the computer is not damaged, but they have shut down some of its operations as a precaution. Operation resumed on 17 August 2015.
