Informationweek article Jack Dongarra, a computing expert at the University of Tennessee who helped design the technology used in testing systems on the Top 500 list, said he expects more 10-petaflop-plus systems next year. "Everything is moving along according to Moore's law, so things are doubling every 18 months, roughly," Dongarra told InformationWeek. Dongarra predicted computer makers in 2017 will have 100-petaflop systems, with "exascale" systems between 2018 and 2020. An exascale, or extreme-scale, computer is expected to be a thousand times faster than a petascale system. "All of these things are dependent on funding," Dongarra said in an interview. "This will happen if the funding is in place for those machines."100 petaflops is 10^17 FLoating-point OPperations/Second. I'll be sure to buy a desktop 100 petaflop Mac so I can read my email much faster than I can now. Seriously, it's incredible to think about the types of simulations they'll be able to run, including much more sophisticated weather models. However, this article said that we'll need 1 zettaflops for full weather simulation. That's 10^21 operations/second!
