The Ibm Deep Blue Supercomputer That Defeated World Chess Champion

Creating the first World Championclass chess computer belongs among the oldest challenges in computer science. When World Chess Champion Garry Kasparov resigned the last game of a six-game match against IBM’s Deep Blue supercomputer on 11 May 1997, his loss marked achievement of this goal. The quest for a “chess machine” dates back to 1769 when the Turk—with a human player hidden inside—debuted...

Protein Folding and the IBM BlueGene Supercomputer

Understanding how proteins fold is an important step in uncovering the mysteries of protein function. To date, the computational resources needed to simulate even the shortest and simplest protein folds have been astronomical. Simulation of larger and more complex folds has been prohibitively expensive. In 1999, IBM announced the start of an effort to build a supercomputer, the BlueGene, to be ...

Massively parallel electrical-conductivity imaging of hydrocarbons using the IBM Blue Gene/L supercomputer

Large-scale controlled-source electromagnetic (CSEM) threedimensional (3D) geophysical imaging is now receiving considerable attention for electrical-conductivity mapping of potential offshore oil and gas reservoirs. To cope with the typically large computational requirements of the 3D CSEM imaging problem, our strategies exploit computational parallelism and optimized finite-difference meshing...

Simulation of High-Resolution Magnetic Resonance Images on the IBM Blue Gene/L Supercomputer Using SIMRI

Medical imaging system simulators are tools that provide a means to evaluate system architecture and create artificial image sets that are appropriate for specific applications. We have modified SIMRI, a Bloch equation-based magnetic resonance image simulator, in order to successfully generate high-resolution 3D MR images of the Montreal brain phantom using Blue Gene/L systems. Results show tha...
