In 1950, Alan Turing, the father of computer science, proposed a test for machine intelligence: Ask a human and a computer a question, and see if another person could discern the digital answer from the biological one. Now IBM engineers have devised a tougher task for Watson, their latest supercomputer: Jeopardy.
IBM's latest supercomputer crunches numbers at enormous speeds--and will soon be put to use for nuclear warfare

IBM has broken its own record of computer processing speed by pushing its newest supercomputer past the petaflop barrier. The Roadrunner, a massive machine occupying 6,000 square feet of space, this week achieved a peak of 1.026 petaflops, or just over one million billion calculations per second. Just ten years ago, the fastest supercomputer in the world would have taken 20 years to finish a problem the Roadrunner is capable of finishing in a week.
Enormous supernova explosions, gamma-ray bursts from distant galaxies, the violent birth of stars, and the incredible consequences of collisions between galaxies or black holes: These are some of the most extreme and mysterious events in the universe, yet our largest telescopes and satellites glimpse only their dim afterglow.
Thats why astronomers use the worlds largest supercomputers to transform theories and formulas into animated 3-D simulations of explosions, collapses and collisions.
