Summary

Researchers at Rice University are investigating whether the use of “inexact computing” can make supercomputers more energy efficient. They are seeking to optimize calculation speeds and decrease the power input needed to yield high-quality solutions.

Extended Discussion Questions

  • If inexact computing is successful in optimizing the energy use of supercomputers, what potential impacts might it have on everyday devices that you use?
  • What are some of the advantages of the traditional high-precision computing approach?
  • The inexact computing approach sacrifices precision for increased efficiency when finding solutions. What level of precision would you be willing to sacrifice? Consider problems such as time keeping on aircraft or GPS positioning for driverless cars.
