Sorry, I meant one to three orders of magnitude. The most expensive computer I know of is the Japanese K computer at ~ 1.25 billion and 10 something Petaflops.

Sorry, I meant one to three orders of magnitude. The most expensive computer I know of is the Japanese K computer at ~ 1.25 billion and 10 something Petaflops. This was mostly politically motivated (Japanese chips) and too costly for what it does IMO. A typical new supercomputer in the Top 500 today is in the order of 100 million.
