The number of registered users of China's fastest supercomputer has crossed 300, the authorities said.
Companies from the US, Canada, Singapore and Sweden are among the users, according to a press release issued Tuesday by the National Supercomputing Center in the northern city of Tianjin.
It provides outsourcing services for complex work like mine surveying, bio-informatics, large-data animation design, nuclear fusion energy research and also marine environmental engineering, Xinhua reported.
With a processing speed of 2.57 quadrillion operations per second, Tianhe-1A was ranked fastest in the world in November 2010, but was surpassed by the Japan-developed K Computer last June, according to the Top500 list of the world's most powerful computers.
Tianhe-1A cost $72.3 million to develop.
