supercomputer competition

In recent supercomputer competition, China's Tianhe-2 (天河二號) retains its No. 1 perch with 33.86 petaflops/s (毎秒3.4萬兆次數學運算). Even its electrical bill is staggering ( 一年一仟七百萬美元電費) . A few supercomputer applications: weather forecast (good for human beings), nuclear weapons simulations (garbage for human beings), decipherment of password (even 天河二號 will need 幾百萬兆年 to crack 256-bit encryption), simulation of molecular dynamics (good for human welfare development). It was guessed that one of the applications in 天河二號 is to develop C919 airliner.
