Supercomputer Tianher-1A
Its name is Tianhe-1A, is located in Tianjin (China) and can execute 2.507 petaflops, that is equivalent to 2.507.000.000.000.000.000 floating point operations per second. Is, therefore, the computer that execute more operations with decimals per second, this doesn't implies that is the more fast in the world, as others say, but is the more fast making this kind of operations.
