The Chinese have taken the super computing crown with the fastest machine on the planet.
The Tianhe-1A Supercomputer, located at National Supercomputer Center in the city of Tianjin, set a performance record of 2.507 petaflops, as measured by the LINPACK benchmark, making it the fastest system in China and in the world.
Tianhe-1A uses 7,168 Nvidia Tesla M2050 GPUs and 14,336 CPUs; it would require more than 50,000 CPUs and twice as much floor space to deliver the same performance using CPUs alone. Nvidia said.
Guangming Liu, chief of National Supercomputer Center, said, "The scientific research that is now possible with a system of this scale is almost without limits; we could not be more pleased with the results."
The Tianhe-1A supercomputer will be operated as an open access system to use for large scale scientific computations.
GPUs like the Tesla chip from Nvida are increasingly being used to build, highly parallel, multi-core super computers at considerably lower cost compared to traditional approaches. The GPU is so powerful that some experts argue that they render password protection ineffective.
