IBM has built
the world's
fastest supercomputer, a machine that can operate at one
petaflop, which is 1,000 trillion floating point operations per
second.
This is twice as fast as
IBM Blue Gene,
the world's previous fastest computer.
Called "Roadrunner", the new supercomputer has been built for
the US Department of Energy's National Nuclear Security
Administration.
It will mainly be used for US nuclear weapons simulations, but
it will also be used for research in areas such as energy,
astronomy, human genome science and climate change.
The computer runs on Red Hat Linux and uses a mixture of
processors.
