Obama orders effort to build first exascale computer.

The United States is now committed to building an exascale computer, some 30 times more powerful than today’s top machine. Yesterday, President Barack Obama signed an executive order creating a national strategic computing initiative, which aims to coordinate high-performance computing research and development between federal agencies. The order should make it easier for agencies to justify increasing their budget requests to Congress for supercomputing R&D.

What is an exascale computer?

Exa is a prefix for 10^18: https://en.wikipedia.org/wiki/Exa-

Exascale computing

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.[1] (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.[2] Enabling applications to fully exploit capabilities of Exascale computing systems is not straightforward.[3]

Exascale computing would be considered as a significant achievement in computer engineering, for it is believed to be the order of processing power of the human brain at neural level (functional might be lower). It is for instance the target power of the Human Brain Project.
