Asking Google... wikipedia: Exascale computing refers to computing systems capable of at least one exaFLOPS, or a billion billion calculations per second. Such capacity represents a thousandfold increase over the first petascale computer that came into operation in 2008. (One exaflops is a thousand petaflops or a quintillion, 1018 , floating point operations per second.) At a supercomputing conference in 2009, Computerworld projected exascale implementation by 2018. deutschlandfunk.de, 18 July 2015 Stromverbrauch würde eine Milliarde kosten Heutige Supercomputer können mehrere Billiarden Rechenoperationen gleichzeitig ausführen. Das scheint gigantisch, Forscher denken aber schon über den nächsten Schritt nach, den Exa-Flops-Rechner: der könnte eine Trillion Rechenoperationen in der Sekunde ausführen – wenn da nicht der Stromverbrauch wäre. zdnet.de, 30 July 2015 US-Präsident ordnet Entwicklung von Exascale-Supercomputer an Philipp Neumann Exascale Computing and Big Data 3 / 29 Terminology Energy Consumption Exascale and Big Data Fault Tolerance Molecular Dynamics What is Exascale?
