<P> Erik P. DeBenedictis of Sandia National Laboratories theorizes that a zettaFLOPS (10, one sextillion FLOPS) computer is required to accomplish full weather modeling, which could cover a two - week time span accurately . Such systems might be built around 2030 . </P> <P> Many Monte Carlo simulations use the same algorithm to process a randomly generated data set; particularly, integro - differential equations describing physical transport processes, the random paths, collisions, and energy and momentum depositions of neutrons, photons, ions, electrons, etc . The next step for microprocessors may be into the third dimension; and specializing to Monte Carlo, the many layers could be identical, simplifying the design and manufacture process . </P> <P> High performance supercomputers usually require high energy, as well . However, Iceland may be a benchmark for the future with the world's first zero - emission supercomputer . Located at the Thor Data Center in Reykjavik, Iceland, this supercomputer relies on completely renewable sources for its power rather than fossil fuels . The colder climate also reduces the need for active cooling, making it one of the greenest facilities in the world . </P> <P> Many science - fiction writers have depicted supercomputers in their works, both before and after the historical construction of such computers . Much of such fiction deals with the relations of humans with the computers they build and with the possibility of conflict eventually developing between them . Some scenarios of this nature appear on the AI - takeover page . </P>

Where do we have supercomputers mention any two areas
