Hecto-scale computing (102)[edit]

  • 2.2×102 Upper end of serialized human through put. This is roughly expressed by the lower limit of accurate event placement on small scales of time (The swing of a conductors arm, the reaction time to lights on a drag strip etc.)[1]
  • 2×102 IBM 602 1946 computer.

Kilo-scale computing (103)[edit]

Mega-scale computing (106)[edit]

Giga-scale computing (109)[edit]

Tera-scale computing (1012)[edit]

Petascale computing (1015)[edit]

Main article: Petascale computing
  • 1.026×1015 IBM Roadrunner 2009 Supercomputer
  • 8.1×1015 Fastest computer system as of 2012 is the Folding@home distributed computing system
  • 20×1015 IBM Sequoia Circa 2011
  • 36.8×1015 Estimated computational power required to simulate a human brain in real time.[4]

Exascale computing (1018)[edit]

Main article: Exascale computing
  • 1×1018 It is estimated that the need for exascale computing will become pressing around 2018[5]

Zetta-scale computing (1021)[edit]

  • 1×1021 Accurate global weather estimation on the scale of approximately 2 weeks.[6] Assuming Moore's law remains constant, such systems may be feasible around 2030.

A zettascale computer system could generate more single floating point data in one second than was stored by any digital means on Earth in first quarter 2011.

Yotta-scale computing (1024)[edit]

  • 1×1024
