Cray's supercomputer at the Department of Energy's Oak Ridge National Laboratory (ORNL) upgraded (doubled) its performance to 119 teraflops - putting it number 2 on the world's Top 500 list of supercomputers:

Japan steps it up a notch in the supercomputing race:

http://www.top500.org/lists/2011/06/press-release
| Quote: | A Japanese supercomputer capable of performing more than 8 quadrillion calculations per second (petaflop/s) is the new number one system in the world, putting Japan back in the top spot for the first time since the Earth Simulator was dethroned in November 2004, according to the latest edition of the TOP500 List of the world’s top supercomputers. The system, called the K Computer, is at the RIKEN Advanced Institute for Computational Science (AICS) in Kobe.
The 37th edition of the closely watched list was released Monday, June 20, at the 2011 International Supercomputing Conference in Hamburg. The ranking of all systems is based on how fast they run Linpack, a benchmark application developed to solve a dense system of linear equations.
For the first time, all of the top 10 systems achieved petaflop/s performance – and those are also the only petaflop/s systems on the list. The U.S. is tops in petaflop/s with five systems performing at that level; Japan and China have two each, and France has one. |

Cray ups the ante with its new XK6 system. Note that a 50-petaflop supercomputer would possess more computing power than the top 500 supercomputers combined.
http://www.eweek.com/c/a/IT-Infrastructure/Crays-XK6-Hybrid-Supercomputer-Will-Combine-AMD-Nvidia-Chips-719730/
| Quote: | HPC organizations are increasingly turning to systems that include GPU technologies as a way of ramping up performance and parallel-processing capabilities while keeping down power and space costs. AMD is rolling out chips under its Fusion banner, in which the graphics, compute and interconnect capabilities are integrated onto the same die. A growing number of systems vendors, including IBM and Appro, are offering hybrid servers to HPC organizations that run both x86 chips and Nvidia’s Tesla 20-Series GPUs.
For developers, Cray’s new system will include a unified x86/GPU programming environment that will include tools, libraries, compilers and third-party software, according to the company.
The system is expected to be available in the second half of 2011, and organizations will be able to configure it in a single cabinet with tens of compute nodes, or a multiple-cabinet system with tends of thousands of compute nodes, with up to 50 petaflops (or 50 quadrillion floating point operations per second) of performance.
Cray already has a customer for the XK6 system—the Swiss National Supercomputing Center, which is upgrading its Cray XE6m system, nicknamed “Piz Palu,” to a multi-cabinet XK6 supercomputer. The center’s systems support a wide range of work by the Swiss research community in such areas as weather forecasting, chemistry, physics, genetics, experimental medicine, astronomy and computer sciences. |

IBM's "Watson" won....but it also missed a question every 5th-grader knows, Toronto is NOT in the US. See "Chinese Room Argument" in "Robot in Every Home" thread.
As computers get more and more "clever" we forget the vast background that is taken for granted in every human communication. Gravity and Time are basic. More obvious in questions of "Capitalism."
