An anonymous reader writes: ZDNet is reporting IBM claims that the Blue Gene/P will continuously operate at more than 1 petaflop — It is actually capable of 3 quadrillion operations a second, or 3 petaflops. IBM claims that at 1 petaflop, Blue Gene/P is performing more operations than a 1.5-mile-high stack of laptops!
