It seems that the computer has a much broader range of applications than reflected above--
"This level of processing power will make Roadrunner ideal for simulating complex interactions in many industries. Applications for Roadrunner will be widespread, including measurement of nuclear decay, complex weather patterns, capital market projections or astronomical calculations. Nanotechnologists and biochemists can explore intricate protein folding simulations or molecular interactions to design new drugs or cellular machines. Movie makers and information scientists will be able to create previously unexplored levels of 3D rendering, both for entertainment and potential real-time modeling of cancer, surgical or other biomedical applications. And oil and gas producers will be able to simulate underground geographies, determining the location of unexplored reserves."
Some of you have plenty of time for inane speculations, but no time to do a simple google search--and you wonder why the folk music revival died;-)
