Submission + - NCSA Launches Blue Waters Supercomputer (chicagotribune.com)

Beorytis writes: The National Center for Supercomputing Applications at the University of Illinois at Urbana-Champaign has set Thursday March 28 as the official launch of its 1 petaflop sustained performance Blue Waters supercomputer. Previous drama surrounding Blue Waters involved IBM's departure from the project which was taken on by Cray for $188 million. Thursday's date is ceremonial as the system is already operational for several projects.

Submission + - A New and Improved Moore's Law (technologyreview.com)

Beorytis writes: "MIT Technology review reports on a recent paper by Stanford professor Dr. Jon Koomey that claims to show that the energy efficiency of computing doubles every 1.5 years. Note that efficiency is considered in terms of a fixed computing load, a point soon to be lost on the mainstream press.

Also interesting is a graph in this related blog post that really highlights the meaning of the "fixed computing load" assumption by plotting computations per kWh vs. time. An early hobbyist computer, the Altair 8800 sits right near the Cray-1 supercomputer of the same era.

Warning: you'll have to get past the usual misstatement of Moore's Law (saying it relates to processing power rather than transistor density)."
