China has apparently become the third country to build a petaflop supercomputer. Xinhua news agency reported on Thursday that the country has unveiled "Tianhe," a 1.206 peak petaflop machine powered by a combination of 6,144 Intel CPUs and 5,120 AMD GPUs, and it runs linpack at 563.1 teraflops. Amazingly, the price tag was a mere $88.24 million. The system is installed at the National University of Defense Technology (NUDT) in Changsha, capital of central China's Hunan Province.  Link   This is about 3 times as fast as the previous record which Microsoft helped to power.
