Blue Waters is expected to be one of themost powerful supercomputers in the world.

Scientists will create breakthroughs in nearlyall fields of science using Blue Waters.

Blue Waters is a joint effort of :

The University of Illinois, its National Centerfor Supercomputing Applications

IBM, and The Great Lakes Consortium for Petascale

Computation.

It is also supported by the National

Science Foundation.

Scientists with the Blue Waters will be able to:

Predict the behavior of complex biologicalsystems.

Understand how the cosmos evolved after theBig Bang.

Design new materials at the atomic level.

Predict the behavior of hurricanes andtornadoes.

Simulate complex engineered systems like thepower distribution system, airplanes and

automobiles.
