A handful of engineers at a lab in Poughkeepsie, N.Y., have assembled what they expect will become--at least for a while--the world's most powerful computer. The IBM Roadrunner likely will go down in history as the first computer to consistently crank out 1 petaflops--a quadrillion floating-point operations per second.
But the true significance of the IBM supercomputer--and many similar efforts gearing up around the world--might not be the milestone of cracking the petaflops barrier. The bigger impact may lie in what the creators and users of these powerful machines are learning about science and how to harness parallel computing.
Leading-edge supercomputers are making great strides in reducing cost and power consumption. But there is a growing gap between their theoretical performance and the amount of real work they can accomplish. The gap is due to the growing complexity of programming systems with many processors.
