The computer, known as Tianhe-1A, has 1.4 times the horsepower of the current top computer, which is at a national laboratory in Tennessee, as measured by the standard test used to gauge how well the systems handle mathematical calculations, said Jack Dongarra, a University of Tennessee computer scientist who maintains the official supercomputer rankings.
China's Tianhe-1A blows away the existing No. 1 machine. Tianhe-1A is not only fast, but due to its reliance on GPUs as well as CPUs, it is also "3 times more power efficient -- the difference in power consumption is enough to provide electricity to over 5000 homes for a year.
The machine was developed by China's National University of Defense Technology (NUDT), which describes itself as "under the dual supervision of the Ministry of National Defense and the Ministry of Education."
